This does not have anything to do with wether S. pileata needs to be split from S. bouvreuil. In: Plumage variability and taxonomy of the Capped Seedeater Sporophila bouvreuil (Aves: Passeriformes: Emberizidae). Zootaxa 2781: 49–62), the authors state “the nominate subspecies originally described as Loxia bouvreuil Muller 1776 is based on “Bouvreuil de l’isle de Bourbon” (plate attributed to Daubenton and Daubenton 1765-66)…” I do not think this is correct.




On Zoonomen is :

and
http://www.zoonomen.net/cit/RI/SP/Loxi/loxi00041a.jpg .

Both were on planche 204 but one was figure 1 and one was figure 2 looking at Richmond’s notes.
Here is Prof. Statius Müller’s Orig. Descr. Of both

Bullfinch the Isle of Bourbon. Pl Enl. 204. Fig. 1.
Idem, bullfinch Cape of Good Hope. Fig. 2.
Mr. Montbeillard thought these two birds were male and female of the same species. This is not right. Hist. Nat. Ois. iv. p. 387 (1778).
Bouvreuil de l'isle de Bourbon, Daubent. PI. Eni. v. pi. 204. fig. 1.
.
Loxia bourbonensis, P. L. S. МШ1. Syst. Nat., Anhang, p. 154 (1776);
Bouvreuil de Cap de Bonne-Espérance , Loxia Bouvreuil is in the synonymy of the Black-headed Canary, (Alario alario?) Serinus alario?

Here is Martinet, Daubenton planche 204 :
http://www.biodiversitylibrary.org/item/109383#page/15/mode/1up .

There are many examples of where ornithologists mixed up where birds were from LeVaillaint is famous for this. (isle de Bourbon = Reunion Isle)The bird in figure 1 looks like the capped seedeater. But it is not named Loxia bouvreuil by Statius Muller he named that bird Loxia bourbonensis. That is not a good name for a bird from South America.

There is a dissertation by Erika Machado Costa Lima which I am sure explains this but my Portuguese is very bad. It is on www. teses.usp.br

Well, this is a little bit messy.

P.L.S. Müller did not give full citations, but rather referred most of his new species simply to "Buffon", which means the "Planches enluminées". The first author known to me who tried to identify Müller's birds was Cassin (1864). Here the mistake was made, as he assigned Loxia bourbonnensis to pl.204, fig.1 and L. bouvreuil to fig.2. Müller's description of L. bourbonnensis, however, reads: "ferruginous, with black head and wings, whose belly is white", whereas L. bouvreuil is described as "wholly ferruginous, and has only black crest, wings and tail".

[This link may work better].

When compared with the plate it is obvious that L. bourbonnensis is based on fig.2 (which was from Cape of Good Hope according to Buffon) and L. bouvreuil on fig.1 (from Ile de Bourbon) instead. So it seems Müller had already mixed up the localities, which partly excuses Cassin's lapsus.

To sum up:

Loxia bouvreuil, description taken from Pl.enlum.204, fig.1 (not 2, as incorrectly given by Cassin), original type locality: Ile de Bourbon (not Cape of Good Hope, as incorrectly given by Müller) (needless to say that Ile de Bourbon is itself incorrect).

Loxia bourbonnensis, description taken from Pl.enlum.204, fig.2 (not 1), original type locality: Cape of Good Hope (not Ile de Bourbon). This is a synonym of Crithagra (=Serinus; =Alario) alario.

It seems that Machado & Silveira (in Zootaxa) had it right.

Since it might not be transparent, races associated to bouvreuil (crypta, saturata) appear to have been subsumed in this treatment within bouvreuil (monotypic).

That is kind of what the abstract says:
ABSTRACT.—An analysis of the morphology, vocalization, habitat preference and distribution revealed that the southern yellow-billed population ascribed to the Plumbeous Seedeater (Sporophila plumbea) is actually an undescribed species. This new species is here characterized. Individuals of this new species are distinguishable from other members of Sporophila, particularly S. plumbea, by a combination of diagnostic characters: (1) the adult male has a robust, bright yellow bill with an arched culmen, distinguishing it from S. plumbea and other gray seedeaters; (2) the adult male is larger and heavier than S. plumbea; (3) the adult plumage of males is bluish gray (not plumbeous gray, as in S. plumbea); (4) vocalizations include song that is structurally similar to that of S. plumbea but with clear (whistled) introductory syllables and unique call notes. The new seedeater is segregated from other gray seedeaters in its breeding habitat and breeding distribution. It is endemic to Brazil, where it breeds in upland shrub-grasslands associated with Araucaria in southern Brazil and migrates northward to the Cerrado to winter.

Can someone with access to the original Auk paper please provide details of the person commemorated by Sporophila beltoni.
With appreciation and thanks in advance.
