 system was adopted in which each individual is oiven one number

So far as possible the type-s})eeiinens. with exception of the cetace- 

 ans, have been taken out of the general stud}- series and placed in se]i- 

 arate storage cases, plainly la])eled on the outside '"Types." A few 

 types, however, are on exhibition among the mounted mammals, or 

 mounted skeh^tons. 



Th(^ orders, families, and genera are arranged in the usual sequence, 

 beginning \\ith the marsupials and ending with the })rimates. A few

 by certain authors in papers in which the natural groups containiiig- 

 such genera are not complcteh' revised. Owing to this lack of 

 general revision as well as the absence of such genera in the current 

 checklists, it has not been deemed advisable to make use of them 

 in this catalogue. It should be observed that the names are given in 

 this list just as they occur in the original descriptions. Frequently 

 the generic tcMin in conuuon use when the sj)ecies was first described 

 is quite difl'erent from th(^ generic designation of lo-day, so that it 

 looks a little ixnuliar to see such names as Cariacus clavatus^ Dor- 

 relapJiiLs crookl^ etc., arranged under the genus Odocolleu><; or KhiK- 

 iiioyiiatkufi Ixiirdl'i^ under the generic name Taplrella^ etc. In such 

 cases, however, the specific name is placed with the current generic 

 designation, but in less cons[)icuous ty|)e than that of the original 

 name, inmiediatel\' following the original citation. Under each genus, 

 the species and subspecies are arranged alphabetically. A complete 

 index will b«> found at the end of the list.
