But isn't that Its junior to Ince?
I think the correct OS is Tine (adj. tiny), with Teene (teeny) a subsequent spelling, presumably later emended into Teense (teensy), then Ince (incy), and finally Its (itsy)...
[OD]; [type specimen]; thanks to Mark Brown.Melanonyx segetum anadyrensis Buturlin, 1908. (OD in Наша охота ["Nascha Okhota"], "Our hunting", again a hunting magazine; not seen by me.)
Based on a male shot on 11 July 1902, in coll. Menzbir.
Type locality given by Buturlin & Dement'ev 1935 as "Post Novo-Mariniskiy"; in Anadyr, but I'm not clear where exactly.
This is, again, a pink-and-black-billed bird (see Buturlin 1934).
Twitter summary by Ottenburghs on this paper:Ottenburghs, J., Honka, J., Müskens, G.J.D.M. & Ellegren, H. Recent introgression between Taiga Bean Goose and Tundra Bean Goose results in a largely homogeneous landscape of genetic differentiation. Heredity (2020). https://doi.org/10.1038/s41437-020-0322-z
Several studies have uncovered a highly heterogeneous landscape of genetic differentiation across the genomes of closely related species. Specifically, genetic differentiation is often concentrated in particular genomic regions (“islands of differentiation”) that might contain barrier loci contributing to reproductive isolation, whereas the rest of the genome is homogenized by introgression. Alternatively, linked selection can produce differentiation islands in allopatry without introgression. We explored the influence of introgression on the landscape of genetic differentiation in two hybridizing goose taxa: the Taiga Bean Goose (Anser fabalis) and the Tundra Bean Goose (A. serrirostris). We re-sequenced the whole genomes of 18 individuals (9 of each taxon) and, using a combination of population genomic summary statistics and demographic modeling, we reconstructed the evolutionary history of these birds. Next, we quantified the impact of introgression on the build-up and maintenance of genetic differentiation. We found evidence for a scenario of allopatric divergence (about 2.5 million years ago) followed by recent secondary contact (about 60,000 years ago). Subsequent introgression events led to high levels of gene flow, mainly from the Tundra Bean Goose into the Taiga Bean Goose. This scenario resulted in a largely undifferentiated genomic landscape (genome-wide FST = 0.033) with a few notable differentiation peaks that were scattered across chromosomes. The summary statistics indicated that some peaks might contain barrier loci while others arose in allopatry through linked selection. Finally, based on the low genetic differentiation, considerable morphological variation and incomplete reproductive isolation, we argue that the Taiga and the Tundra Bean Goose should be treated as subspecies.
According to Ruokonen and Aarvak (2011), the sister taxa johanseni and middendorffii were basal to both
Ottenburghs et al. (2016) does not include Middendorf's Bean-Goose and does not match up well with Ruokonen and Aarvak (2011)
However, the morphology of the eastern Bean Goose taxa (A. s. serrirostris and A. f. middendorfii) will need to be assessed to obtain a complete picture of morphological variation within the Bean Goose complex

Thanks Mark.Here is it online:
It is a report of a meeting where Mr. Bartlett approves Gould's name Anser serrirostris. But from where? MS?
Interestingly, this description did not make it at all into the PZS covering the same meeting: https://www.biodiversitylibrary.org/page/30680680.ZOOLOGICAL.--March 23rd.--Professor Owen Vice President in the chair. The papers read were:-- [...] 4. 'On a new species of Goose from China, collected by the late Lieut. Ince at Shanghai,' by John Gould, Esq., F.R.S. This goose resembles the Grey Lag Goose, Anser ferus, in the form of the bill, but the upper and under mandibles, together with their terminal points, are black, and there is a light coloured space or bar between the nostrils and the end of the bill. In the general colour of the plumage the bird has a strong resemblance to the Bean Goose, Anser segetum; it differs, however, from this last in size, and by its thick and powerful bill, which is further characterised by being unusually strongly serrated. Mr Bartlett, who had made a special study of the Geese, fully confirmed Mr Gould's opinion of the specific value of the bird in question, and the author proposed to distinguish it by the name Anser serrirostris.
