It has been thought that the European and American specimens 

 were the same ; but the anatomical descriptions show the following 

 difi'erences : — 



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

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



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

 third co-ossified); dorsal 11; posterior 37. — Cuv. 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. Coloui* imiform 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, cyHndrical, and anteriorly subglobose. Body 

 sHghtly compressed. Tail strongly compressed, almost carinated, 

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

 in largest part 10, length of pectorals 3 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 B. Grampus, Hunter, and D. glohkeps, 

 Cuvier, by the caudal constriction, as weU as in its foi-m, 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 ill-defined, narrow, clouded, white streak, extending 

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

 some parts than othei's, and most so beneath the jaw. 



" Vertebra) 58 ; bodies of the six cer\'ical co-ossified. It was a 

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

 tomj'." — Jackson, Boston Journal Nat. Hist. 1845, v. 160. t. 15. f. 1. 



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

 D. globiceps, but not so well as an old cranium in the same museum. 

 The upper surface of the maxillary bones in both specimens was 

 less broad and flatter than he represents them. 



In the Paris Museum there is a skull of this genus from Guada- 

 loupe, named D. globiceps. The middle of the intermaxillaries is 

 as wide as the maxilla?. Skull : length, entire, 23| inches, of nose 

 114 ; width at notch 85, at middle of beak S\ inches.
