stomach contained many hundred cuttle-beaks placed one within the 

 other, as in the othei- specimen. Another specimen, probably his 

 female mate, was seen swimming about the same locality for three 

 weeks, but floundered o^.—Byerley . 



Mr. Thomas Thompson (Mag. Nat. Hist. 1838, ii. 221) describes, 

 under the name oi Hiiperoodon honjloriensis, a specimen stranded near 

 Hull in 1837 ; it has two strong, robust teeth at the extremity of 

 the lower jaw, covered and entirely concealed by the gums. The 

 skull corresponds in its general form with the figures in Cuvier ; 

 but the rise of the back part of the head is larger in proportion to 

 the anterior rise than in that figure. The skull measures from the 

 snout to the base of the front rise 9 inches ; thence across the rise 

 to the base of the second rise 1 foot ; thence across the hinder rise 

 to the neck 1 foot 11 inches. The length of the skeleton is 17 feet 

 6 inches ; vertebrae 39, viz. 7 cervical, 9 dorsal (with ribs), 20 lumbar, 

 and 3 caudal. The skeleton is in the Museum of the Hull Philo- 

 sophical Society. It agrees in all particulars with Hunter's speci- 

 men in the Royal College of Surgeons. Mr. Thompson considers 

 Hunter's and Baussard's cetaceans identical, and Dale's the male of 

 the same species.

M. Wesmael examined the palate of \ho female Hyperodon stranded 

 at Borgsluis near Ziercczee, in Holland, and found the surface of it 

 quite smooth and without any appearance of the small, hard, acute 

 points mentioned by Baussard. The upper jaw was without any
