ON SPECIES OF SOUTH AMERICAN DELPIIINID ,.K 



DESCRIBED BY DR R. A. PHILIPPI 



IN 1893 AND 1896. 



BY FREDERICK W. TRUE. 



In 1893 Dr. R. A. Philippi, Director of the National Museum 

 of Chili, described several new species of porpoises and com- 

 mented on various South American forms previously known. 

 In 189G he supplemented this by a second paper on the same 

 subject.* 



These two papers constitute a valuable contribution to the 

 knowledge of the Delphinidw of South American seas, but, on 

 account of lack of access to recent literature, or for some other 

 reason, many of the different forms are assigned to genera to 

 which they can at present hardly be considered to belong. As 

 I have given the family Delphinidce considerable study and have 

 examined the types of the majority of the species described by 

 Gray and other cetologists, I venture to express below my 

 opinions as to the probable affinities and correct scientific names 

 of the various forms described or mentioned by Dr. Philippi.
