GL0I5ICEPHALUS SIEBOLDII Gray. 



Delphinus cjlobiceps, Schlegel, Faima Japon., Mammalia, 1844 (?), p. 17, p. 27, figs. 



1-4. 

 Globiocephaliis Sieboldii, Gray, Zool. Erebus and Terror, 184G, p. 32. 



I should be inclined to pass over this species as founded upon too 

 young a specimen to be seriously considered, were it not that in Schle- 

 gel's figure of the exterior at least one peculiar character is indicated. 

 This character relates to the shape of the pectoral fin. In other spe- 

 cies the pectoral fins come gradually to an acute termination, but in 

 Schlegel's animal they are represented as being fully one-half as broad 

 immediately behind the extremity as across the middle. This gives 

 the fins an entirely different appearance from those of the other species. 

 If the figure is correct, and if the character proves constant, Schlegel's 

 specimen must be regarded as belonging to a distinct species. The 

 animal was so young that tlie characters of the skull are not of great 

 importance. The extremity of the vomer has the appearance of being 

 bifurcated, one-half being applied to the wall of either intermaxillary 

 bone. This disposition of parts is found in the species of some genera, 

 but not in other species of Globicephalus. 



Resting upon so insufficient a basis, the- species must be looked upon 

 as of doubtful value, until more specimens from the waters of Japan 

 have been acquired and studied. It will very probably jirove to be 

 identical with Q. scammonij to which its uniformly black coloration 

 and expanded intermaxillse show it to be allied. 



Globiocephalus anstralis ami sibo, Gray. 



Glohioecplialua australis is merely a name inserted by Gray in the 

 Supi)lement to the Catalogue of Seals and Whales (p. 85). It was never 

 described.
