wards to open into a large chamber, 5 in. by 3 in. in diameter ; 

 thence a short canal passes into a second chamber of less 

 dimensions, the hinder wall of which rests against the roof of 

 the skull. The anterior wall is fleshy, and evidently capable 

 of considerable movement in contraction and expansion. This 

 lower chamber is somewhat pear-shaped, with the narrow end 

 downwards, and thence a very narrow short canal opens into 

 the naso-palatine canal. 



Owing to the removal of the lower jaw I am unable to 

 describe the form, size, or position of the mouth, which is 

 described by other zoologists as small, and situated some 

 distance from the tip of the snout. The lower jaw is pro- 

 vided on each side with thirteen conical, pointed, and slightly 

 curved teeth; each tooth fits into a pit in the gum of the upper 

 jaw. In the upper jaw are only two teeth, situated far for- 

 ward, and carried by the premaxillary bones. On the right 

 side the tooth projected from the gum for T 3 F in., but the left 

 tooth had only just " cut " the gum, so that only the extreme 

 tip projected. 



The alimentary canal had been torn out of the body, but 

 the stomach was preserved and the intestines and contents 

 examined. The length of the intestine is about 32 yards, of 

 which the small intestine measured 30 yards ; then it dilated 

 to form a great sac a yard or so in length and 10 in. across, 

 filled with dark-brown, almost black, fluid of considerable 

 consistency, which consists of " sepia," or contents of the 

 ink-sacs of the cuttlefishes upon which the whale had fed. 

 The stomach contained great quantities of squid-beaks, lenses 

 of squids' eyes, and pens of squids. Von Haast's suggestion 

 that the whale feeds on " smaller hydroid zoophytes" is an 

 error, due partly to the absence of beaks in the stomach of 

 his specimen. ' Van Beneden and Gervais suggest, from 

 the form of the teeth, that Cogia probably feeds on fishes 

 (p. 354) rather than cuttles. I found no trace of fish. 



The Skeleton. 



As I have above indicated, I was able to obtain a complete 

 skeleton." There is one bone which, however, may have 

 been present — the pelvic bone. But I carefully examined the 

 region in which it should lie, and, moreover, removed and 

 dissected the penis, of which an illustrated account appears in 

 another journal.! 



* This skeleton has been purchased by the Cambridge University 

 Zoological Museum; and an illustrated account of certain bones has 

 been laid before the Zoological Society by me, and will be published in a 

 forthcoming volume of the Proceedings of the Society.
