It is only necessary to compai'e the figures of the two skulls given 

 in the plate of Middendorff, above referred to, to see the distinction 

 between the skulls of the Carrion- and Ant-Bear of Northern Siberia. 

 The Carrion-Bear (U. collaris) has a short, broad skuU, with a short 

 nose and small, short lower jaw; the Ant-Bear has an elongated, 

 narrow skull, with an elongated nose and a large, strong lower 

 jaw : the lower jaw in the first is three-fifths, in the second five- 

 sevenths the length of the skull. 



Var. 4? stenorostris. 



Nose of the skuU produced, attenuated. Lower edge of lower jaw; 

 arched.

Edb. Europe, Poland. 



Only known from a skuU in the Paris Museum. It is very difife- 

 rent from the other skull from Poland ; the nose is much more pro- 

 duced ; the crown more evenly convex ; the forehead raised more 

 suddenly from the nose ; the lower edge of the lower jaw curved, 

 much arched up behind. I have not seen it : it may be only an 

 accidental variety. 



2. TJrsus lasiotus. 



Black, nose brownish. Ears covered externally with soft and 

 internally with long hairs, forming a projecting tuft. Fur elongate, 

 forming a large tuft on the throat.

Dr. Sclater thinks that the Bear here described may be the TJrsus 

 aretos, var. du Kamschatka, of I. Geofeoy, in the ' Zoology of the 

 Voyage of the Venus,' t. 4, to which M. Pucheran has given the 

 name of U. piscator, Eev. Zool. 1855, p. 392. One might think 

 that it is very probably the same Bear by the habitat given ; but the 

 figure does not represent any of the peculiarities of the Bear as seen 

 living in the Zoological Gardens, and is much more like a figure of 

 the common Ursns aretos of Europe, both in form and colouring. Did 

 the artist make his sketch from the European Bear instead of the 

 one found in Siberia ? As the description does not point out any of 

 the characters which induced me to regard the living Bear as a dis- 

 tinct species, I am inclined to use the name I described it by. 



3. TJrsus isabellinus. (Indian White Bear.) B.M. 



Fur dirty white or yellowish ; hairs of the back and nape elon- 

 gated, very soft, curled, of the sides rigid, adpressed ; claws short, 

 straight, and blunt j forehead of skull convex over the orbits, sepa- 

 rated from the nose ; palate flat, rather slender, narrow ; the upper
