 acinaces mais il a le corps plus allongé, et la seconde épine 

 dorsale et les pectorales relativement plus courtes II est moins 

 rare que Tacinaces, mais n'a pas été trouvé jusqu'ici, hors 

 Tlnsulinde, que dans les mers de File Savay. 



Diapterus arggreus Blkr. 



Descriptio Güntheriana sequens. 



//The height of the body is scaroely more than the length 



of the head, and one-third of the total (without caudal fin) ; 



the diameter of the eye is one-third of the length of the 



head, and rather longer than the snout, the extent of which 



equals the distance between the eye. The groove for the pro- 



cesses of the intermaxillary bones is entirely scaleless, and 



does not extend to the vertical from the centre of the eye. 



The spines of the fins are slender ; the second of the dorsal 



is one-half of the height of the body, and more than twice 



the length of the second anal spine, which is rather stronger 



but not longer than the third. Silvery; top of the dorsal 



blackish. D. 9/10. A. 3/7. Lin. lat. 45. "
