the nose is arched ahove. The zygomatic arch is much more beut 

 out, especially at the hinder end. The hinder opening of the palate 

 is -wider, and arched in front ; the suborbital apertui'e is oblong, 

 triangular, arched beneath, and nearly as high as wide. 



Hah. Nepaul {Hodgson). 



The imperfect skull above described is in Mr. Hodgson's collec- 

 tion, and named Lutra monticola ; but it is very unlike the skull 

 of either of the two other siiecimens so named. It agrees with the 

 skull of Baranr/ia sumatrana in the entire want of the tubercular 

 process on the side of the frontal bone, which usually defines the 

 hinder upper edge of the orbit ; but it differs from it in so many 

 particulars that I am convinced that it must indicate a separate 

 species. 



** The muzzle partially hairy ; front and upper edge of the nostrils bald, 

 with the hair coming down in an angle betiveen them in front. 



10. LONTRA. 



The muzzle hairy in the middle in fi'ont ; upper and front edge of 

 the nostrils bald and callous ; the ears oblong, hairy. Toes strong, 

 covered with hair above, half webbed ; webs bald ; claws strong, 

 acute ; palms and soles bald ; pads well developed and divided. 

 Tail conical, covered with hair. Skull dilated behind ; nose veiy 

 short, broad ; forehead broad, flattened above ; hinder edge of orbit 

 marked with acute tubercles above and below ; flesh-tooth with a 

 very large rounded internal lobe extending the whole length of the 

 tooth ; tubercular grinders rather broader than long. The under- 

 fur very soft, scattered with short stiffer hairs.

Hah. Cayenne (B.M.). 



M. F. Cuvier does not describe the peculiarity of the muffle ; so 

 that I am not certain that this is the species he describes. 



2. Lontra brasiliensis. (The Brazilian Otter.) B.M. 



The hair on the centre of the nose forming a narrow erect band ; 

 fur pale brown ; upper lip, chin, and beneath rather paler.
