Cheomis tetrastigma, sp. u. (Plate LIY. fig. C.) 

 D. fQ. A. ^. L. lat. 30. L. transv. f^. 



Teeth distinctly bicuspid, brown at the tip, the inner cusps 

 being larger than the outer ; from twenty-eight to thirty-two on 

 each side of the outer series of the upper jaw. Scales belo^^' the 

 eye in three series. In a specimen 4| inches long the diameter 

 of the eye exceeds the width of the prjeorbital, the depth of the 

 scaly portion of the cheek, and the W'idth of the hiterorbital space, 

 which is flat. The angle formed by the pra^opercular limbs is 

 nearly a right one. The height of the body is rather more than 

 the length of the head, which is one third of the total (\A'ithoLit 

 caudal). The length of the last dorsal spine is two fifths of that of 

 the head. Pectoral fin extending to the origin of the anal. The 

 upper and lower caudal rays covered with scales. Scales smooth. 

 A series of four large black spots on the body — the first on the 

 operculum, the second on the lateral line opposite to the ninth and 

 tfuth dorsal spines, the third on the beginning of the lower lateral 

 line, the fourth on the root of the caudal tin. Vertical and ventral 

 tins blackish, the dorsal with numerous ocelli. 



Several specimens, of which the largest is 4| inches long, are 

 sent from Zomba and from Eort Johnston. 



Chromis callipterus, sp. n. (Plate LV. fig. B.) 



D. -^. A. ^, L. lat. 27-28. L. transv. -^^f' 



Teeth distinctly bicuspid, the cusps being short, subequal, and 

 brownish ; from twenty-seven to thirty-two (in very young speci- 

 mens twenty-two) teeth on each side of the outer series of the 

 upper jaw. Scales below the eye in three series. In a specimen 

 5| inches long the diameter of the eye equals the width of the 

 prseorbital and of the interorbital space, but is a little less than 

 the depth of the scaly portion of the cheek. The angle formed 

 by the prjEopercular limbs is a right one. The height of the 

 body is rather more than the length of the head, which is one 

 third of the total (without caudal). The longest dorsal spine is 

 the last and rather less than one half of the length of the head. 

 Pectoral fin extending to the origin of the anal; caudal more or 

 less scaleless. Scales ronghened, with minute projections on the 

 margin. Body dark-coloured, with the vertical fins blackish, the 

 anal being ornamented by a series of large milky-white ocelli from 

 two to four in number ; in our largest specimen also the dorsal 

 fin is ornamented with round light-coloured spots, A black band 

 running from the eye to the angle of the mouth seems to be 

 constant. 



The largest specimen is 5.] inches long, and was sent by the 

 Jiev. J. A. Williams; smaller sjx'cimcns from Zomba are in the 

 Johnston collect ion.
