November 9, 1841. 
William Horton Lloyd, Esq., in the Chair. 
A letter from E. L. Moore, Esq., dated Newfoundland, September 
21, 1841, was read. In this letter Mr. Moore returns his thanks to 
the Society for having elected him a corresponding member, and ob- 
serves that no exertion on his part shall be wanting to forward its 
views. 
Mr. Gould exhibited and pointed out the characters of a new 
species of Goose nearly allied to Nettapus Coromandelianus (Anas 
Coromandeliana, Auct.), from N. Australia, which he characterized 
as 
Nerrarus PULCHELLUS. Nett. collo, dorso, alisque intensé resplen- 
denti-viridibus ; lateribus, fasciis latis lineisque alternatim albis 
et viridescenti-nigris, conspicue ornatis ; remigibus secondartis cum 
pogoniis externis albis, undé fascia obliqua alam transcurrens. 
Male: head brownish green, indistinctly barred with light brown, 
beneath the eye an oval spot of white ; neck, back and wings deep 
glossy green; primaries black; outer webs of the secondaries snow- 
white; feathers of the chest and back of the neck white, with a 
number of greenish black circles, one within the other, so numerous 
that the white is nearly lost; the flanks similarly marked, but in 
them the bars and circles are broader and more apparent ; tail black, 
glossed with green ; abdomen white ; under tail-feathers black ; irides 
dark brown; bill dark greenish grey, with a yellowish white nail; 
under mandible greenish grey, irregularly blotched with a lighter 
colour; legs and feet blackish brown. 
Total length, 125 inches; bill, 14; wing, 64; tail, 3; tarsi, 1. 
The female resembles the male, but differs in having the crown, 
occiput, and a stripe down the back of the neck deep brown; in 
being destitute of the white spot beneath the eye; in having the 
chin and upper part of the throat white, mottled with small mark- 
ings of brown; bill french grey, becoming yellowish at the base; 
lower mandible bluish grey; tarsi fleshy white on the sides; back 
and front blackish brown ; feet dark brown. 
Mr. Waterhouse called the attention of the members to a new 
species of Rodent from Chile, which had been placed in his hands 
for description by H. Cuming, Esq. This animal, Mr. Waterhouse 
stated, evidently belonged to a little family of the Rodentia (the Oc- 
todontide), which is peculiar to the southern parts of South America, 
a family of which six species are characterized, and these constitute 
the four genera, Ctenomys, Poephagomys, Octodon, and Abrocoma. 
The present Rodent agrees with the two first of these genera in 
No. CVI.—Procrxrpines or THE Zoot. Soc.
