The signature is dated April 1860 (at the foot of [p.103]). That should in principle indicate the time of printing.
(Printed is still not equal to published, though; publication requires the distribution of the printed item.)

According Priority!:

SI copy include p. 103 in a second state

sig 19 pp. 279-286; CRW* reported that pp. 103-286 made up issues 4/9 [and so p. 103 must have occured in two states] and that theres pages bear the date 'June 1861'!

But a next question. Berlepsch wrote here about Uranomitra quadricolor (Vieill.)

...same as the bird which we used to call U. cyanocephala. in his description of Trochilus quadricolor....
Click to expand...

Which would fit to William Jardine here or the plate here.

So Vieillot may have described Trochilus quadricolor in 1822. Lessons description seems from 1830 here.

So why no priority to Vieillot?
 
I am a little bit confused about the status of Amazilia viridifrons rowleyi in OD is written:

Appears intermediate between A. v. viridifrons and A. (v?) wagneri but closer to the former from which it differs in more extensively vinaceous-cinnamon flanks and axillars....

So is it a synonym, a valid subspecies of either Amazilia viridifrons or Amazilia wagneri, a separate species or a hybrid?

Was this issue ever properly analysed?

HBW Alive (here) says:
... Birds from C Oaxaca have been awarded race rowleyi, but probably represent intergradation with wagneri in zone of supposed secondary contact. Two subspecies recognized.

If of any help?

I have not read this:
https://onlinelibrary.wiley.com/doi/full/10.1111/jav.01536 . It might address rowleyi?

No. It is only about the relationship/gene flow Amazilia viridifrons, Amazilia villadai and Amazilia violiceps and the question it to spilt Amazilia villadai as a seperate species or lump Amazilia violiceps including A. villadai into Amazilia viridifrons.

But if we read here Amazilia viridifrons rowleyi is equal to Amazilia wagneri.

Calothorax

Yuyini Licona-Vera, Juan Francisco Ornelas, Susan Wethington, Kelly B Bryan; Pleistocene range expansions promote divergence with gene flow between migratory and sedentary populations of Calothorax hummingbirds, Biological Journal of the Linnean Society, , bly084, https://doi.org/10.1093/biolinnean/bly084

Abstract:

We investigated the influence of postglacial population expansion on the genetic structure of reproductively isolated populations that come into secondary contact and produce hybrid zones. We tested migratory behaviour to explain geographical patterns of genetic diversity and phylogeographical structure in migratory and sedentary populations of hummingbirds in the Chihuahuan Desert. We assessed genetic structure, demographic expansion and introgression in Calothorax hummingbirds using mitochondrial DNA (mtDNA) and nuclear microsatellites and used ecological niche modelling to predict where migratory and sedentary populations resided during Pleistocene climate events. Bayesian analysis yielded three clusters. However, only two clusters matched mtDNA haplogroups, one parental in the south (C. pulcher) and a cluster with two admixed taxa (sedentary and migratory C. lucifer) that cannot be attributed to any pure parental population. Demographic expansion, gene flow and admixture in the C. lucifer range, postglacial northern expansion predicted by ecological niche modelling, and approximate Bayesian computation strongly supported a scenario of divergence with gene flow: a Pleistocene basal split separating C. pulcher; and the other two clades are derived from a second split (migratory and sedentary C. lucifer). Population genetic admixture was higher in localities with lower inferred stability of habitat suitability. The genetic differentiation of Calothorax may be explained by the combined effects of the following factors: (1) gene flow and recent postglacial northern expansion from southern sedentary populations; (2) increased genetic admixture with lower stability of habitat suitability; and (3) the evolution of long-distance seasonal migration during glacial–interglacial cycles, suggesting a role for diversification through the divergence of migratory subpopulations that become sedentary.
 
If HBW key is correct than Trochilus Adolphei Lesson, 1843 OD here is a synonym to Phaethornis ruber nigricinctus Lawrence, 1858 OD here. I am wondering why Lessons name has no priority?

Phaethornis adolphi Gould, 1857 OD here can't be the reason as the plate an text are part of delivery 14 from Gould from the year 1857 or here as Pygmornis Adolphi. Therfore Lesson would have priority. What do I miss?


I think I found the answer myselfe ashere is written:

Lesson's entire diagnosis is very brief, being quite at variance with the detailed descriptions he customarily provided. No mention is made, for instance, of the facial pattern or of the rufous uropygial patch, both of which are conspicuous features of these birds. The paper in which the account appears is, in fact, a mere
summary of the species which the author planned for a supplementary fourth volume of his "Histoire naturelle" of the hummingbirds-a volume that was never published although 100 plates were said to have been prepared for it. "Trochilus Adolphei" was to be figured on plate 24. If this "manuscript" plate is still in existence, it might be possible to determine precisely to which form the name properly applies. There is enough uncertainty at present to make me unwilling to supplant the name nigricinctus, whose application is unquestionable, by adolphei, which is still in doubt.

Would be interesting if this plates and/or the specimen still exist.

Somewhere in the back of my head is a thought that Prince Weid bought these plates of Rene Lesson to New Harmony but they ended up being given to Philadelphia Academy of Natural Sciences by William MacLure. ????

Could be as here is written:

While in Europe he purchased the copper-plate illustrations of some important works both to Science and Art, with the intention of having them republished at home in a cheaper form, in order to render them accessible to all classes of learners.

But does not clearly telling me that this are unpublished plates.

Or here is written:

M. Lesson possède de nombreux manuscrits écrits dans la silence, une histoire des Méduses avec plus de 200 figures coloriées, un tome 4e d'Oiseaux mouches et un volume d'illustration avec devélins de M. Prêtre. Il s'est livré à une sérieuse de monumens de la Saintone, une des provinces les plus riches, les moins connues de la France; il se priver des choses les plus nécessaire pour se former une bibliotèque qui est fort riche en livres d'ornithologie, et pour solder ses secrétaires et ses peintres.

Oreotrochilus cyanolaemus sp. nov.

Francisco Sornoza-Molina, Juan F. Freile, Jonas Nilsson, Niels Krabbe, and Elisa Bonaccorso (2018) A striking, critically endangered, new species of hillstar (Trochilidae: Oreotrochilus) from the southwestern Andes of Ecuador. The Auk: October 2018, Vol. 135, No. 4, pp. 1146-1171.

Abstract:

We describe a new species of the genus Oreotrochilus from the southwestern Andes of Ecuador. The new species is most similar in adult male plumage to O. stolzmanni and O. chimborazo. However, male and female show unique combinations of plumage characters that are likely to act as social signals. Phylogenetic analyses based on mitochondrial DNA indicate that this new taxon is closely related to O. stolzmanni and O. melanogaster, whereas genetic distances and preliminary comparisons of vocalizations suggest a sister relationship with O. stolzmanni. The geographic distribution of the new species seems to be restricted to cordillera Chilla-Tioloma-Fierro Urcu, in the southwestern highlands of Ecuador, an area historically poorly explored by ornithologists. Thus, based on its restricted distribution, apparently low population size, and lack of protection of its habitat, we evaluate it as critically endangered.

Proposal (808) to SACC:

Species limits in Oreotrochilus

A. Elevate Oreotrochilus estella stolzmanni to species rank

B. Recognize newly described Oreotrochilus cyanolaemus
