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

 large, oempying the whole of the inner side of the outer portion of the 

 tooth ; the hinder dentiferous portion of the mamllary bone, bearing the 

 ypper tubercular grinder, produced 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 skin!fe belonging to the skulls with the large teeth are in a very 

 bad condition ; they are probably bleached.

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

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



6. Lutra Swinhoei. 



Lutra (Hydrogale) Swinhoei, Gh-ay, P. Z. S. 1867, p. 182. 



Two imperfect skulls sent by Mr. Swinhoe from Formosa certainly 

 belong to two very distinct species. 



The most perfect skuU, 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 grinder 

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

 second section, which I have called Lutrogale. 



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

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

 the series forming only a width of 4| hnes ; while the series 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 Up, chin, and beneath paler. Fur rather 

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

 flesh-tooth with a very large internal lobe, as long as the tooth. 

 Claws large, acute.
