and the lower jaw more massive, with of course two teeth, 

 indicative of the male sex ; the tail is shown with a mesial 

 notch, and the conspicuous keels, both on the upper and lower 

 surfaces of the termination of the body, are absent ; the dorsal 

 fin is much less falcate and the pectoral limbs longer, narrower, 

 and less pointed than in the Overstrand specimen. The colo- 

 ration, " black above, nearly white below," and the sides 

 " completely covered with white vermicular streaks in every 

 direction," differs materially from the specimen we had the 

 opportunity of examining. 



Keinhardt, J. " Mesoplodon h'ldeiifi, en Tilvaext til den danske 

 Havfauna," Oversigt over d. K.. D. Vid. Selskabs, 1880 (Kjoben- 

 havu), p. 63, tab. ii. (adult female, side view, and dorsal view 

 of head and part of the body). — This appears to be a very good 

 figure ; the external auditory meatus is shown in much the 

 same position as in the Overstraud specimen, but the contour 

 of the head differs in having a deep depression at the base of 

 the skull and in the body being less fusiform. The animal had 

 been dead for over a month when Eeinhardt examined it *, 

 and, except in a few places, nearly all the cuticle was removed, 

 which may account for the auditory meatus being so con- 

 spicuous, probably also for the occipital depression already 

 mentioned. The only reference to colour is the statement that 

 the remains of the epidermis and the interior of the mouth were 

 blackish. On the shrinking of the integuments two small 

 functionless teeth about the size of a pin's head were seen on 

 each side of the upper jaw, so loosely lodged that they were 

 freely movable ; a third could be felt on cutting into the skin, 

 and, more posteriorly, apparently a fourth, but no trace of 

 teeth could be found in the mandible, though the author suggests 

 that they also were probably present in this specimen.

 of the caudal fin is not accurately drawn, and both the dorsal
