Weight estimated at 255 lbs. Length, from nose to end of tail,

 9J, to penis 49, to anus 56 inches ; span of tail 21 ; pectoral fin 5| 

 across the base, 21 inches along the anterior edge, and 6 inches along 

 the posterior ; circumference in front of dorsal fin 46 ; blowhole 

 concave anteriorly and 1| inch across from tip to tip ; eyes iths of 

 an inch. Vertebrae 58; bodies of six of the cervical co-ossified; 

 11 dorsal, and posterior to them were 40. — Jackson, I. e. 



It has been thought that the European and American specimens 

 were the same ; but the anatomical descriptions show the following 

 differences : — 



1. American. Vertebrae 58 : cervical 7 (bodies of first six co- 

 ossified) ; dorsal 11 ; posterior 40. — Jackson, I. c. 166. 



2. European. Vertebrae 55: cervical 7 (bodies of second and 

 third co-ossified) ; dorsal 11 ; posterior 37. — Ouv. Oss. Foss. v. 



Above shining black, side of the abdomen and neck marked with 

 the continuation of the white colour of the abdomen and throat ; 

 beneath varied with white. Tail compressed, terminating in a deep 

 constriction before the caudal fin. Colour uniform black above, 

 with a white patch beneath the throat, becoming a narrow longitu- 

 dinal stripe on the breast between the fins, and a broad longitudinal 

 band on the abdomen. Teeth about twenty in each jaw, small, 

 prismatic, slightly reflected, and projecting half an inch above the 

 gums. Head blunt, cylindrical, and anteriorly subglobose. Body 

 slightly compressed. Tail strongly compressed, almost carinated, 

 and much constricted just before the caudal fins. Length 16g, girth 

 in largest part 10, length of pectorals 8 feet 11 inches, gape of 

 mouth 9. Pectoral fins one-fourth, dorsal fin 'one-thirteenth of the 

 total length. 



" Inhab. New England. A female. 



" Distinguished from J). Qrampus, Hunter, and D. glohiceps, 

 Cuvier, by the caudal constriction, as well as in its form, propor- 

 tions, and markings. 



"A specimen harpooned at Craigie's Bridge,16th June,1842, looked 

 quite thin. It was a uniform dark slate-colour, except the belly, 

 where was an Ul-deflned, narrow, clouded, white streak, extending 

 from beneath the jaw to almost the anus, being much broader in 

 some parts than others, and most so beneath the jaw. 



" Vertebrae 58 ; bodies of the six cervical co-ossified. It was a 

 male, 7 feet long, and weighed about 255 lbs. Teeth |-^.— See ana- 

 tomy." — Jackson, Boston Jov/mal Nat. Hist. 1845, v. 160. 1. 15. f. 1. 



The cranium agreed pretty well with Cuvier's figure of that of 

 B. glohiceps, but not so weU as an old cranium in the same museum. 

 The upper siuface of the maxillary bones in both specimens was 

 less broad and flatter than he represents them. 



In the Paris Museum there is a skuU of this genus fiom Guada- 

 loupe, named D. glohiceps. The middle of the intermaxiUaries is 

 as wide as the maxillae. SkuU : length, entire, 23^ inches, of nose 

 11| ; width at notch 8|, at middle of beak 8| inches.
