as deep. Silveiy, witli or without dark ci'oss-bars; sometimes an 

 interi-upted lateral band ; an opercular spot ; usually a bar below 

 eye ; soft dorsal and caudal sometimes spotted ; males with ocelli 

 on anal fin. 



Several specimens, 90 to 135 mm. in total length. 



The remarkable phaiyngeal dentition might well be held to 

 justify the genus Labrocliromis (Regan, 1920), were it not that in 

 all other characters the species is nearly identical with H. cinereus.

 Lijyochromis ('Annals,' 1920).
