In the Museum of the College of Surgeons is a skull (no. 1138, 

 Hunterian) apparently belonging to another species of this genus.

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

 coast of Japan, and called Sahamata huzira. It is said to have a 

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

 and sides near the pectoral fins ; the eyelids and lips pale purple, 

 the latter often white-spotted. The head is rounded ; the iipper 

 jaw pointed and toothless ; the lower short and narrow, and toothed. 



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

 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.

10. PHOCffiNA. 



Dorsal fin in the middle of the body. Skull-nose depressed, broad ; 



the hinder part of the maxilla slightly shehang downwards over the 



orbits. The intermaxillaries and vomer form part of the palate. 



Teeth numerous, spathulate, compressed, extending nearly the whole 



length of the jaw.

The foetus of Phocama has two bristles on each side of the nose ; 

 as the animal grows, these bristles fall out, and each leaves a small 

 pit on the side of the nose, which Klein (Hist. Piscium, i. 24) 

 mistook for the nostrils, as has been weU observed by Professor 

 Eschricht, 250. 



"NMien the mouth is closed the upper lip overlaps the under one 

 evenly aU round. The part of the under Hp that is covered by the 

 upper one is flat, and slu^lving inwards. It is of a paler colour than 

 the upper lip and the lower part of the lower one.
