MAMMALS OF THE PHILIPPINE ISLANDS. 41 



Many of these names are surely synonyms, while a few are 

 probably valid for species or subspecies of Philippine deer. 

 Until series of deer skulls from all parts of the Philippine 

 Islands, and especially from the type localities of all described 

 forms, are assembled for study, it will be impossible satis- 

 factorily to deal with these names. I have arranged them al- 

 phabetically by species, regardless of the genus in which they 

 have been described. As no complete list of these names, with 

 references and type localities, has ever been published, and for 

 general uniformity, the reference to each name is given in full 

 as throughout the list. No attempt has been made to improve 

 on the combination employed by the describer.
