49G ACCOUNT OF THE ARCTIC BEGIONS. 



DiiLPhiNus Deductor, (Traill).-^ Ca'ing or Leading 

 Whale. 



Two original descriptions of this animal are be- 

 fore the public, the one by Mr P. Neill *, the other 

 by Dr Traill f . The paper of Dr Traill is accom- 

 panied by a drawing, taken by Mr James Watson 

 on the spot, where 92 of the species had just been 

 driven on shore. This drawing, judging from the 

 known accuracy of Mr Watson, in connection with 

 the opinion of different persons acquainted with the 

 animal, is doubtless, in the general appearance, a 

 faithful representation. In the engraving, Plate 13. 

 fig. 1, this drawing is minutely copied, excepting a 

 small reduction in the diameter, which, with the 

 permission of Dr Traill, I was induced to make, in 

 consequence of the comparative diameter of the fi- 

 gure not exactly corresponding with the actual ad- 

 measurement of the animal. 



The following are the specific characters, as given 

 by Dr Traill. Body thick, black ; one short dorsal 

 fin ; pectoral fins long, narrow ; head obtuse ; upper 

 jaw bent forward ; teeth subconoid, sharp, and a lit- 

 tle bent.
