86 CETACEA. 



M. Schlegel (Faun. Japon. 25) described a dolphin found on 

 the coast of Japan, and called Sakamata kuzira. It is said to 

 have a high dorsal, and to be black with white spots on the belly, 

 back and sides, near the pectoral fin. The eyelids and lips pale 

 purple, the latter often white-spotted ; the head is rounded, the 

 upper jaw pointed and toothless; the lower short and narrow 

 and toothed. 



Schlegel, who refers this species to D. Orca, says the want- 

 ing teeth in the upper jaw is a mistake ; but it is probably a 

 Grampus, which often wants them in that jaw. I do not see 

 why one part of the description should be relied on and not the 

 other. 



In the Museum of the College of Surgeons is a skull (No. 1 138, 

 Hunterian) apparently belonging to another species of this 

 genus. 



The teeth are 12-12, small, conical, curved, very acute. Nose 

 rather concave on the sides ; intermaxillaries nearly as wide as 

 the jaws. Lower jaw obliquely truncated in front. Length, en- 

 tire, 24 inches; of nose 12, of tooth-line 7, of lower jaw 19 

 width at notch 9, of middle of beak 6|, at orbits 15| inches. 



9. GLOBIOCEPHALUS. 



Head round, forehead very prominent. Teeth conical, large 

 only on the front half of the jaws ; deciduous in the old one. 

 Upper jaw largest? Pectoral narrow, linear-ovate, low down. 

 Dorsal falcate, about the middle of the back. 



Skull flattened and concave in front of the blower ; nose broad, 

 flattened, rugose above ; intermaxillary bones very broad, cover- 

 ing the greater part of the upper surface of the upper jaws ; the 

 hinder wing of the jaw-bone horizontal and bent up on the edge 

 over the orbits, and slightly expanded and reflexed just in front 

 of the orbit notch. 



The sucking young have no visible teeth ; the adults have teeth 

 in each jaw, but the aged individuals have generally lost them in 

 both. Fleming.

 old specimens it is well-marked. Jackson, Bost. Journ. N. H. v.
