6" THE VOYAGE OF H.M.S. CHALLENOER. 



to 400 fathoms, so that the exact depth could not be accurately ascertained for every 

 species. However, as some of the species obtained on that occasion belong, or are 

 closely allied, to well known genera of shore fishes, I have considered it safer to include 

 these at least in the present series than to enumerate them among the deep-sea forms. 



Bathyanthias, n. gen. (Percidae). 



Form of the body similar to that of Antkias. One dorsal fin with nine spines ; anal 

 with three ; caudal truncated. Teeth in villiform bands, in the jaws, on the vomer 9.nd 

 palatine bones, without canines. Tongue smooth. Prseoperculum finely serrated, without 

 projection. Scales of moderate size, very finely ciliated. Branchiostegals seven. Coast 

 of Brazil. 



Bathyanthias roseus, n. sp. (PI. I. fig. B). 



D. -j^, A. f, L. lat. 58, L. transv. -^-g. The length of the head is nearly equal to the 

 depth of the body, and one-third of the total length (without caudal). Eye as long as 

 the snout, and two-sevenths of the length of the head ; interorbital space flat, but much 

 narrower than the orbit ; maxillary extending to below the middle of the eye ; the 

 vomerine teeth form a triangular patch, the palatine bands being very narrow. Six 

 series of scales on the cheek. Prseoperculum very finely serrated on its posterior margin 

 and with the angle rounded ; operculum without spine. Caudal and anal fins scaly, but 

 the soft dorsal scaleless. Dorsal spines rather feeble, the third being the longest, and about 

 one-third of the length of the head ; pectoral fin falciform, extending to the anal, and not 

 quite so long as the head ; ventrals only half as long. The lateral line ascends rapidly 

 from its origin towards the spinous dorsal, and runs close to the upper profile, descending 

 again behind the dorsal to the middle of the tail. Colour, uniform rose-coloured, with 

 two faint lighter longitudinal bands. Length of specimen 4^ inches. Station 122 ; 30 

 or 350 fathoms. 



Centrop^'istis anfiularis, n. sp. (PI. I. fig. C). 



D. -^, A. f, L. lat. 60. Margin of the praeoperculum rounded, without stronger 

 spines at the angle ; operculum with three spines. Eeddish, with two incomplete black 

 rings behind the eye, with a large, saddle-shaped spot on the back of the trunk, and with 

 some small black dots on the dorsal fin. Off" Pernambuco. Length of specimen 

 2 inches. Station 122; 30 or 350 fathoms.
