Chkomis kirkii, sp. n. (Plate LVI. fig. A.) 



D. J. A. ^. L. lat. 29. L. trausv. ^. 



Teeth distinctly bicuspid, each with two subequal brownish 

 cusps, from seventeen to nineteen on eacli side of the outer series 

 of the upper jaw. Scales below the eye very thin, in three 

 rather irregular series. In a specimen 4| inches long the diameter 

 of the eye is rather more than the width of the pra-orbital or than 

 the depth of the scaly portion of the cheek, but equal to the width 

 of the interorbital space, which is flat. The angle formed by the 

 pra3opercuIar limbs is an obtuse one. The height of the body is 

 two fifths the length of the head, one third of the total (without 

 caudal). The longest dorsal spine is not quite one half of the 

 length of the head. Pectoral tin extending to, or a little beyond, 

 the origin of the anal fin. Caudal fin covered with miuute scales. 

 Scales rough, with miuute projections on the margin. A rather 

 narrow straight black stripe runs from the opercular spot to the 

 end of the lateral line ; another similar band, but broken up into 

 spots, runs along the side of the back, and is absent in very young 

 individuals. The soft dorsal with oblique, alternate, lighter aud 

 darker bauds. jS^o band across the pra'orbital. 



Several specimens, the largest being 4^ inches in length. 



Chromis williamsi, sp. n. (Plate LYI. fig. C.) 



D. ^. A. ^. L. lat. 28. L. transv. j^. 



Teeth deeply bicuspid, brown at the tip, the inner cusps being 

 much larger than the outer ; twenty-six or twenty-seven on each 

 side of the outer series of the upper jaw. Scales below the eye in 

 four series ; the scales on the neck between the anterior dorsal 

 spines and the beginning of the lateral line are remarkably small. 

 In a specimen 4^ inches long the diameter of the eye exceeds the 

 width of the pr.eorbital, is equal to the depth of the scaly portion 

 of the cheek and less than the width of the interorbital space, 

 \Ahich is rather convex. The angle formed by the pra;opercular 

 limbs is a right one. The height of the body is a little more than 

 the length of the head, which is one third of the total (without 

 caudal). The length of the last dorsal spine is less than one half 

 of that of the head. Pectoral fin not quite reaching the vent ; 

 caudal fin covered with scales. Scales rough, without spines on 

 the margin. Body nearly uniform dark-coloured, with a black 

 spot on the end of the operculum, and another at the root of the 

 caudal fin ; vertical fins blackish, the dorsal with a broad black 

 margin and the anal with a small milkj^-whife spot between the 

 fifth and sixth rays. 



A single specimen, 4^ inches long, obtained by the Eev. J. A. 

 Williams.
