The skeleton in the Museum of the College of Surgeons (pro- 0- 
bably Hunter’s) has the skull about 45 mches long, and the ele 
vated plates of the maxillary bone are thin, leaving a broad spac 
between them, in front of the blowers, and they are as hig 
the frontal crest. j 
Mr. Pearson of the Hull Philosophical Society, Mr. Ball ¢ 
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 a 
Liverpool, and the French skeleton which has lately been added 
to the Anatomical Museum of Paris) appear all to belong to on 
species, and to be the same as Hunter’s specimens in the College 
of Surgeons, and the skull figured by Camper and Cuvier. _ "4 
Mr. Thompson (Mag. Nat. Hist. 1838, 221) describes a speci- 
men stranded near Hull m 1837; it has two strong, robust teeth 
at the extremity of the lower jaw, covered and entirely concealeé 
by the gums. The skull corresponded in its general form with 
the figures in Cuvier; but the rise of the back part of the heae 
is larger m proportion to the anterior rise than in that figure. 
The skull measures from the snout to the base of the front ise 
9 inches; from thence across the rise to the base of the seco n¢ 
rise ] foot; from thence across the hinder rise to the neck 1 foc 
llinches. The length of the skeleton is 17 feet 6 inches; ver: 
tebre 39; viz. 7 cervical, 9 dorsal, with ribs; 20 lumbar and 
caudal. It is in the Museum of the Hull Philosophical Society 
It agrees in all particulars with Hunter’s specimen in the Colleg 
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. 6 Mag. Nat. His 
1846, 150. t. 4. iv. 375, the following description and measure 
ment of a recently caught specimen; he calls it H. Butzkopf. — 
‘‘Blackish lead hue, merely a lighter shade beneath, and no 
white. Teeth, two on each side, in front loosely covered by th 
gums; the front pair smaller; blower slightly crescent pomtd
