1 66 PATAGONIAN EXPEDITIONS: ZOOLOGY. 



Felis cahis Linn.). The task of assigning to them their proper designa- 

 tions is by no means simple ; the subjoined synonymy is an effort toward 

 that end. In reviewing the names proposed for the numerous subdivi- 

 sions of the Linnaean genus Felis, the number of synonyms based on a 

 single species (at least five or six on Felis planiceps, and about the same 

 number on F.jnbata) is hardly less surprising than the frequency with which 

 the same name has been used for widely different groups. 



Severtzow, in a remarkable paper on the Felidae, published in 1858, 

 divided^ the family into five genera and twenty-seven subgenera, to 

 nearly all of which he gave new names (/. c, X, pp. 385-389), regardless, 

 in large part, of those given by previous authors. In most cases his sub- 

 genera were monotypic, and in addition to the names he adopted, he also 

 provided alternative names for about one-fourth of them. We have hence 

 names ready made for probably all possible contingencies. Yet a number 

 of others were added by J. E. Gray in 1867, ^ but fortunately very few have 

 hten proposed since that date. ^
