24 GILPIN PORPOISES AND DOLPHINS OP NOVA SCOTIA. 



in form. From its posterior edge the line of back sloped rapidly 

 to the tail. The lower line of belly sloped gently to posterior edge 

 of flipper ran straight to beneath dorsal, then rapidly upwards to 

 tail. The dorsal and pectoral fin (flipper) were both falcate. 

 The back behind the dorsal became carinated, ending in a ridge 

 between the caudal fins. The mouth was formed into a beak or 

 snout, with gentle curves. The eye black, about two inches from 

 mouth, the lines of which ran upward. The blowhole on the 

 forehead, between the eye crescentic concave forwards ; ear, a small 

 puncture. In colour the beak was white with tips of both jaws 

 black (in one specimen the lower jaw was all black). The back, 

 fins and tail blue-black. There were three irregular ill-defined 

 white spots shaded by black dots on the sides, the black of the 

 upper parts shading gradually into bluish ash around them. The 

 eye was in a whitish spot, and there were two faint parallel white 

 lines running along; the sides and losing themselves in the white 

 patches. The belly was pure white, with a tolerably well defined 

 edge. The eye was dark reddish black. On inside the mouth the 

 palate was white, with a black triangular spot on the point. The 

 palate membrane was very thick, apparently holding the teeth firm- 

 ly, as there were no alveola processes, and the teeth dropped freely 

 out after removing the membrane. The teeth were pointed and 

 slightly incurved ; twenty-two in upper jaw, lower jaw twenty-five 

 on each side. There were no teeth at the points of either jaw. It 

 seems probable that the teeth vary in different individuals. The 

 genital organs are concealed in a deep fold in both sexes. In the 

 female may be seen two smaller folds on each side of the larger one 

 concealing milk paps. On opening the body and removing the 

 blubber the muscle was very full of blood, deep red, and coarse 

 fibre. The heart and blood vessels, and lungs very well developed 

 and full of blood. The liver moderate, the kidneys with well- 

 developed ureters and bladder of urine. The stomach very capa- 

 cious, constricted in several parts, resembling the colon of a horse. 

 Inside the mucus membrane deeply corrugated, in some parts a 

 deep rose colour, suddenly succeeded by pale pearl, answering to 

 the constrictions.
