The dorsal fin is said to be 12 feet from the blower, but that 

 makes the body too long for the measurement. 



a. Teeth. Liverpool. 



The skeleton in the Museum of the College of Surgeons (pro- 

 bably Hunter's) has the skull about 45 inches long, and the ele- 

 vated plates of the maxillary bone are thin, leaving a broad space 

 between them, in front of the blowers, and they are as high as 

 the frontal crest. 



Mr. Pearson of the Hull Philosophical Society, Mr. Ball of 

 Dublin, and Mr. W. Thompson of Belfast, have sent me various 

 detailed drawings of the head of the Hyperoodons taken off the 

 British and Irish coasts, in their possession ; they (the skeleton at 

 Liverpool, and the French skeleton which has lately been added 

 to the Anatomical Museum of Paris) appear all to belong to one 

 species, and to be the same as Hunter's specimens in the College 

 of Surgeons, and the skull figured by Camper and Cuvier. 



Mr. Thompson (Mag. Nat. Hist. 1838, 221) describes a speci- 

 men 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 corresponded 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 ; from thence across the rise to the base of the second 

 rise 1 foot ; from thence across the hinder rise to the neck 1 foot 

 11 inches. The length of the skeleton is 17 feet 6 inches; ver- 

 tebrae 39 ; viz. 7 cervical, 9 dorsal, with ribs ; 20 lumbar and 8 

 caudal. It is in the Museum of the Hull Philosophical Society. 

 It agrees in all particulars with Hunter's specimen in the College 

 of Surgeons. Mr. Thompson considers Hunter's and Baussard's 

 cetacean as identical, and Dale's the male of the same species. 



Mr. W. Thompson has given in the Ann. fy Mag. Nat. Hist. 

 1846, 150. t. 4. iv. 375, the following description and measure- 

 ment of a recently caught specimen ; he calls it H . Eutzkopf. 



"Blackish lead hue, merely a lighter shade beneath, and not 

 white. Teeth, two on each side, in front loosely covered by the 

 gums ; the front pair smaller ; blower slightly crescentic, pointed
