238 DEEP-SEA FISHES OF THE ATLANTIC BASIN. 



horizontal below last rays of dorsal. Snout blunt; mouth oblique; maxillary broad and 

 scaly. Fins with a tendency to filamentous production of the rays. Caudal forked. (Jor- 

 dan.) 



This genus has been found in deep water in the Pacific. Anthias megalepis, Giin- 

 ther,* was taken off the Ki Islands, at 1-10 fathoms, in company with the Centropristis 

 already referred to, and Anthias eos, Gilbert,! taken in the Gulf of California at 112 fathoms. 



A specimen (Cat. No. 37346, U. S. N". M.) obtained by the Fish Hawk, has been mis- 

 placed, and cannot now be fully described. The name Anthias aquilonaris has been pro- 

 posed by us for it. It is allied to Anthias oculatus, C. & V. 



A note indicates that the length of its head was equal to the height of its body, which 

 is contained 2J times in the total length (without caudal). The diameter of the orbit is con- 

 tained 3^ times in the head. The maxillary bone was naked, rather than scaled as in A. 

 oculatus; and the scales numbered 53 in the lateral line, 7 above and 14 below. The radial 

 formula was D. x, 11 ; A. in, 8. 



A small specimen, possibly of the same species, was obtained by the Blake, off Domi- 

 nica, at station cvi, in 521 fathoms; but since this is less than 2 inches long and the 

 subject of the above note was 9, it is impossible to confirm the identification in the 

 absence of the larger specimen.
