NEOCYTTUS*, Gilchr. 



Body deep, strongly compressed ; head moderately compressed, the interorbital region 

 broad. Mouth moderate ; upper jaw with a narrow band of very small pointed teeth ; 

 sometimes a few similar teeth near the symphysis of the lower jaw and on the vomer. 

 5 or 6 branchiostegals. Scales small, imbricated, with spiny edges ; lateral line complete, 

 curved anteriorly. Dorsal with VII 31-34 rays, the spines strong ; anal with III 29-31 

 rays. Caudal tru.ncate. Pectorals short, obtuse, each with 17-21 rays ; ventrals each 

 with I 6 rays, inserted a little behind the base of pectorals, narrowly separated at the 

 base, not folding into a sheath. 



Allied to Oreosoma, C. & V., and Cyttosoma, Gilchrist, which have the ventral fins 

 below the pectorals and more widely separated at the base, and have some or all of the 

 scales juxtaposed and tubei'cular. 



82. Neocyttus acanthorhynchtis, sp. n. (Plate 23. fig. 3.) 



Back elevated, the profile from head to origin of dorsal fin concave. Depth of body 

 If in the length, length of head 2f . Diameter of eye 2\, interorbital width 2f in the 

 length of head. Maxillary extending a little beyond anterior edge of eye ; lower jaw 

 as long as eye. Bones of head with spinulose ridges ; prseorbital ending in a strong 

 antrorse spine, below which are 1 or 2 others directed obliquely downwards ; similar

 has smaller scales than iV. acantliorhynchus and no strong spines on the snout.
