Lutra macrodus, Gray, P. Z. S. 1865, p. 128. 



Hah. Brazil (Parzudaki). Male and female. 



This Otter is about the size of Lontra brasiliensis ; but it is at 

 once distinguished from that species by the large size of the naked 

 muzzle and the harshness of the fur. It is very like L. vulgaris ; 

 but the inner lobe of the flesh-tooth appears considerably larger ; 

 and M. Parzudaki assured me that he had received the pair direct 

 from Brazil, from a collector who shot them. 



12. NUTRIA. 



Like Lutra externally, with tlie bald muffle transverse, narrowed, 

 and arched below. Skull short, broad. Nose broad. Forehead flat ; 

 the orbit defined behind by a well-marked conical tubercle alcove and 

 below. The flesh-tooth with a very largo internal lobe, extending 

 the whole length of the tooth. Hinder portion of the palate short. 

 Nutria, Gray, P. Z. S. 1865, p. 128. 



This genus is at once known from the Otter with the large internal 

 lobes to the flesli-tooth, by the shortness and breadth of the skull 

 and the shortness of the hinder contracted portion of the palate. 



Nutria felina. B.M. 



Fur dark brown, with scattered, flat, whitish-tipped hairs. Lips, 

 sides, and beneath pale brown. The web of toes scattered with hairs 

 above.

Mr. Tomes observes, " The Otter collected in Guatemala by 

 Mr. Salvin agrees with the description and figure of L. cliilensis 

 (Waterh.), especially in the inner lobe of the flesh-tooth having the 

 same angular form as in that species. In L. platensis the inner lobe 

 of the flesh-tooth approaches more or less to a semicircular form. 

 Dr. Baird figiires the flesh-tooth of L. canadensis as in L. platensis " 

 (P. Z. S. 1861, p. 280).
