b. Forehead and nose of skull convex ; the inner lobe of the Jlesh-tooth very 

 large, occupi/in;/ the whole of the inner side of the outer 2}ortion of the 

 tooth; the hinder dentiferous 2wrtion of the maxillary bone, bearing the 

 upper tubercular grinder, ^n-oduced behind the hinder edge of the orbit. 

 Lutrogale.

The Museum has received skulls of two distinct species under the 

 above name, one with large and the other with small inner lobe to 

 the flesh-tooth. 



The skins belonging to the sk^^lls with the large teeth are in a very 

 bad condition ; they are probably bleached. 



Consult also Lutra simul, Horsf. Zool. Journ. ; MiiUer, Verhand. 

 p. 51 ; from Sumatra and Borneo, with strong falcate claws. I have 

 not seen this species, nor Lutra Tcatah (Hiigel, Eeise) from Cashmere. 



6. Lutra Swinhoei. 



Lutra (Hydrogale) Swinhoei, Gray, P. Z. S. 1867, p. 182. 



Two imperfect skulls sent by Mr. Swinhoe from Formosa certainly 

 belong to two verj^ distinct species. 



The most perfect skidl, which wants the cutting-teeth, belongs 

 to the first section of the genus as defined in this Catalogue, with 

 moderate-sized tubercular grinders, and a moderate-sized inner lobe 

 to the flesh-tooth. 



The second, on the contrary, which only consists of the front 

 portion of the upper jaw, with the teeth in change from the milk to 

 the permanent series, has a very large square tubercular gi-iuder 

 and a very large rounded internal lobe to the flesh-tooth, as in the 

 second section, which I have called Lutrof/ale. 



I propose to indicate this species by the name of Lutra Swinhoei. 

 It is easily characterized by the small size of the upper cutting-teeth, 

 the series forming only a width of 4^ lines ; while the scries of most 

 other Indian Otters occupy 6 lines (or half an inch), or sometimes 

 rather more. 



** America. 



7. Lutra macrodus. B.M. 



Dark brown ; upper Hp, chin, and beneath paler. Fur rather 

 harsh. Upper edge of the bald muzzle straight, transverse ; the 

 flesh-tooth with a very largo internal lobo, as long as the tooth. 

 Claws large, acute.
