 while retaining this latter name, he accepted macrodns, Clraj', 

 as being an older name, as a substitute for ellioti. But consider- 

 able changes, in even this revised arrangement, are necessar3^ The 

 name lutra, L. is older than vulgaris and must be used for it. After 

 careful examination of all the Museiim material, Mr. Thomas agrees 

 with me that the specimen which must be taken as the type of 

 tarayensis is the same species as macrodus, (other specimens show 

 that monticola, of which the actual type skin is lost, is also the same 

 species). As the older name therefore tarayensis must take the 

 place of macrodus, for the Smooth Indian Otter. These changes
