According to Poey the Centropristis macrophthalmus of Miiller & Tros- 

 chel was based on tbe young of this species; if so, tbe latter name has 

 tbe right of priority. This si)ecies agrees well with the descriptions of 

 Aprion filfimentosus, (0. & V.) from the islands east of Africa, but it 

 would be premature to write two species from such widely separated 

 localities without actual com])arison of specimens. 



Tbe resemblance of the cranium of this species to that of IJtelis ocula- 

 tus has already been noticed by Poey and Gill. 



Vir.— Genus ETELIS.

The syuouymy and relations of this interesting genus have been well 

 discussed by Dr. Gill in the paper above cited. In spite of the differ- 

 ence in the form of its dorsal, the relations of Etelis with Aprion are 

 very close. The skulls in the two are almost identical, as has already 

 been noticed by Poey and Gill.
