In general form the animal more resembled a Globicephalus than any other Cetacean 
with which I am acquainted—so much so that I was at first inclined to refer it to that 
genus. The front part of the head was furnished with a similar rounded adipose pro- 
tuberance, though developed to a less extent; and the pectoral fins had almost the same 
low position and narrow faleate form, though they were considerably less elongated ; 
the dorsal fin, however, was higher. A better idea of the general form of the body 
can be obtained by an inspection of the figure (PI. I. fig. 1) than by any description. 
The crescentic aperture of the blow-hole, 14 inch in width, was placed directly over 
the eyes. The minute external auditory meatus (no larger than a hole made by pricking 
the skin with a needle) was an inch lower than the eye-aperture, and 34 inches behind 
its hinder angle. 
From the blow-hole the upper contour of the head was continued at first nearly hori- 
zontally forward, then curved pretty rapidly downwards to form the nearly vertical 
anterior surface of the head. This was somewhat hollowed in the middle line, and 
expanded below into a thick, rounded, very short snout, which projected 13 inch further 
forwards than the edge of the lower lip. 
The lower jaw was narrowed in front. The opening of the mouth was directed slightly 
upwards towards the angle, but finally took a sweep downwards near the junction of the 
upper and lower lips. There were no traces of teeth in the upper jaw; but there was a 
deep narrow groove along the alveolar margin of the palate. In the lower jaw, near 
the anterior or symphysial region, were three rather small teeth on each side, the apices
