and sending no process to the neck. The spleen and a spleniculus 

 together scarcely so big as a walnut. A flat rounded gland, about 

 three-fourths of an inch in diameter, situated above the renal vessels 

 on each side, and at a distance of upwards of an inch from the kid- 

 ney, had more the appearance of a lymphatic gland than of the supra- 

 renal body. 



On opening the chest, each lung was seen to be covered with lym- 

 phatic vessels, running to a gland at the sterno-ventral aspect of the 

 free edge of the lung. The gland was very juicy, had every appear- 

 ance of a lymphatic gland, and measured one inch and a quarter long 

 and five-eighths broad. This pulmonary gland in the adult is harder, 

 more fibrous, and less juicy, and measures four and a half inches long 

 by two broad. 



The stomach with two chief compartments ; the first continuing 

 backwards on a line with the gullet, and lined, like it, with a white 

 thick smooth membrane and epithelium ; the second, or true digest- 

 ing stomach, lined with a mucous membrane in folds, and somewhat 

 smaller than the first, of a more rounded form, and extending from 

 its middle to the duodenum. In the first was a quantity of thick;* 

 opake, whitish fluid, and in the second a little mucus. 



There was no gall-bladder. The bile-duct, close to the duodenum, 

 was as thick as a goose quill. The last portion of the intestine was 

 full of meconium, like that of the human foetus. 



There was no csecum ; the intestines were nearly uniform in size 

 throughout, their surface smooth and not at all cellulated. Length 

 of the whole intestinal canal, from stomach to vent, thirty feet. 



The kidneys large and lobulated throughout ; the lobules from a 

 quarter to half an inch in diameter, and having each a very delicate 

 capsule of connecting tissue. The blood-vessels enter the kidney, not 

 near its middle, but at its fore and inner or atlanto-mesial end. 



The mesenteric glands moderate in size and number, of uniform" 

 consistency, and without any cavity or hollow in them, unlike those 

 of the whale described by Mr. Abernethy. 



The womb with two horns, and the ovaries in the usual situation ; 

 mammary slits on a level with and near to the orifice of the vagina. 

 Urinary bladder empty, and the urethra opening just behind the 

 clitoris. 



Descriptive Characters. — Teeth conical and slightly curved inwards/ 

 from eight to twelve on each side of the jaws, making from thirty-two 

 to forty-eight teeth altogether ; but eleven on either side of each jaw 

 is a common number, and there is sometimes one more in the upper 

 than in the under jaw on each side. Dorsal fin large, convex above 

 and extending behind into a hooked or curved point. Pectoral fins 

 long, narrow, and tapering to a point. Tail crescent-shaped. Mouth 

 sloping downwards and forwards. Eyes above and behind the angles 

 of the mouth. Top of the head round, and not prominent, though 

 the snout is remarkably so. No nipples y<et protruding, but merely 

 a longitudinal mammary slit on each side of the orifice of the vagina 

 in the female ; a large penis in the male. Skin smooth, shining, and 

 black throughout, save two whitish-brown patches at the throat and
