We do not admit this genus into the system without serious doubts 

 as to its validity. The scales on the operculum are deciduous in all 

 tlie species of Chromis, and sometimes every trace of scales and of the 

 cutis is lost on one side, whilst tliey are present on the other. The 

 tj'pical specimens have five branchiostegals, and not seven as stated 

 by Kiippell. 



1. Sarotherodon melanotheron. 



Riippell, I. c. 



My friend Dr. D. Weinland has examined the typical specimens 

 at my request, and it is evident from bis remarks that this sjiecies is 

 closely allied to Chromis niicrocephnlus: there are the same propoi-- 

 tions of tlis head, tbe same numbers of doi'sal ajid anal s]Mnes, and of 

 scales. The form of the teeth appears to be exactly tlie same as 

 in that species, but they are less in ntmdxn-, viz. about sixty-six iji 

 the upper jaw and forty lour in the lower. Tbe l(t\v'(M- jiiw is black.
