the nose is arched above. The zygomatic arch is much more bent 

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

 is wider, and arched in front; the suborbital aperture is oblong, 

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



Hah. Nepaxil (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 specimens so named. It agrees with the 

 skull of Barangia 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. 



•* TTie mussxle partially hairy ; front and upper edge of the nostrils bald, 

 with the hair coming down in an angle between them infrcmt. 



10. LONTRA. 



The muzzle hairy in the middle in front ; 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. SkuU dilated behind ; nose very 

 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.

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 hand ; 

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