any gonyx. Teeth small, slender, |^, five in an inch of margin. 

 The palate flat; the hinder part of the palate in front of the internal 

 nostrils broad, swollen, with a very shallow central groove with 

 rather convex sides, and very oblique, flat, external sides. 

 _ Length of skull 15i inches, of beak 9^, of brain-case 6^, of lower 

 jaw 12|- ; width over condyles 6| inches, at notch 3 inches 4 lines, 

 in middle of beak 1 inch 8 lines. 



The two bladebones are rather different in general form, one being 

 more truncated behind than the other ; they are both truncated in 

 front, and in both the coraeoid process is large, with a short upper, 

 and a long straight lower edge ; one has a long, regularly arched, 

 and the other an equally long, but sinuous upper edge, showing 

 that, considering the bladebone a specific distinction, some allow- 

 ance must be made for occasional variation. 



The skull is much like some of the skulls I have named Clymene 

 Boris ; but perhaps I have included several species under that name, 

 as some of the skulls difi"er in the form of the hind part of the 

 palate. The one here described differs from all of them in having a 

 more slender and attenuated beak. 



Dorsal fin high, rather acute at the tip. Black, sides with minute 

 white specks ; the sides of the body above the base of the pectoral 

 to the base of the tail blackish grey, which colour is obhquely ex- 

 tended as a lunate band from behind the vent to the back near the 

 base of the tail.
