chilensis, but the skull presents the character just mentioned. 

 The measurements indicate that the rostrum of the skull is 

 longer relatively than in melas, and the cranium narrower. In 

 Dr. Philippi's two skeletons the number of vertebras was 54 

 and 57 respectively. If the specimens were complete, this would 

 indicate a specific difference, as in G. melas there are 59 or 60 

 vertebrae. 



Globiocephalus grayi Burmeister, with which Dr. Philippi 

 compares his specimens, does not belong to that genus, but is 

 identical with Pseudorca crassidens Reinhardt. 



"Delphinus chilensis Philippi" (1896, p. 10, pi. 2, fig. 3). 



This species is founded on a foetus 24.6 cm. long. It is 

 probably either a Delphinus or a Prodelphinus, but one can 

 hardly hazard an o.pinion without knowing something of the 

 characters of the skull, which is neither figured nor described 

 by Dr. Philippi. It seems undesirable to found species on foe 

 tal specimens in this difficult group of animals. The uncertain 

 ties are already sufficiently formidable, and ought not to be 

 added to. 



"Eutropia dickii Gray" (1896, p. 11). 



An examination of the type of this species which I made in 

 1884, convinced me that it belonged to the genus Cbphahrhyn- 

 chus. The correct name is C. eutropia. (See Bull. 36, U. S. 

 Nat. Mus., p. 112.) 



"Tursio? panope Philippi" (1896, p. 14, pis. 4-6, fig. 2). 



I confess that I am unable to determine even the genus to 

 which this singular species belongs. The quite thin orbital 

 edges, the (apparently) separate pterygoids and straight man 

 dible suggest Lissodelphis, but the small number of teeth and 

 above all the extraordinary curviture of the expanded proximal
