1865.] DR. J. E. GRAY ON THE MUSTELID®. 115 
Mustela javanica, §c., Seba, Thesaur. 177, t. 48. f. 4. 
M. erminea, var., Pallas, Zoogr. Ross.-Asiat. 92 (from Seba). 
Mustela gale leucogenis, Schinz, Syn. Mamm. i. 344 (from Seba), 
Var. 1. Spot before ears and that on forehead confluent. B.M. 
Var. 2. With a small white spot under the eyes. B.M. 
In some specimens the feet are white or brown, with white toes ; 
and in others the feet are brown-yellow. 
Hab. Mexico, Matamoras (Baird); California. 
Var. brasiliana. Feet white; underside bright yellow. B.M. 
Hab. Brazil. 
Dr. Spencer Baird refers M. brasiliensis, Sewastonoff, to this spe- 
cies with great doubt, though it is a very good description, and mo- 
derate but characteristic figure. 
9. MusTeLA AUREOVENTRIS. B.M. 
Dark brown ; head and tip of tail blacker; chin and sides of the 
throat white; a spot in front of ears, throat, chest, insides of fore 
legs, and belly golden yellow ; whiskers black ; tail rather tapering, 
as long as the body; soles of the hind feet hairy; ears rounded, 
hairy. Length of body and head 12, tail 8 inches. 
Var. Fore feet brown, with one or two toes white. 
Mustela aureoventris, Gray, Proc. Zool. Soc. 1864, p. 55, pl. vit. 
(young); not M. auriventer, Hodgson. 
Hab. Ecuador, Quito (Gould) ; New Granada (Fraser). 
This may be a darker variety of the MW. brasiliensis, wanting the 
spot on the forehead. The young from Quito is much darker than 
the adult ; I. zanthogenys is intermediate as regards the spot on the 
head. 
10. MusreLta xAntTHoGenys. Yellow-cheeked Weasel. B.M. 
Brown ; tip of tail black ; spot before the ears, chest, and be- 
neath yellow; a small spot under each eye and the chin white ; 
feet white.

Zool. Voy. Sulphur, t. 9; Cat. Mamm. B. M. 66. 
Putorius xanthogenys, Baird, Mamm. N. A. 176. 
Hab. California. 
Very like MW. brasiliensis; but the head is coloured like the back, 
and the spot before the ears is yellow. There is a very small white 
spot over the orbit on one side. 
M. de Blainville (Ostéographie) figures the upper jaw of a Mus- 
éela under the name of MW. patagonica, with small teeth and a very 
short brim-like transverse tubercular grinder, that is quite unknown 
to me, and very unlike M/. humboldtii, figured on the same plate. 
4. Vison. 
Body elongate, slender. Limbs stout ; feet rather hairy ; pads
