 28-29 ~ ; lat. 1. -g^. Dark olive-brown above, yellowish beneath ; 

 a black opercular spot, followed by a rather indistinct dark band,

Total length 135 millim. 



Three specimens from Sapelle and one from Ossomari. 



I have much pleasure in naming this fish after Dr. Pellegrin, of 

 the Paris Museum, who is at present engaged on a monogi^aph of 

 the Cichlida?, and who has pointed out to me the specific distinct- 

 ness of this Felniatochromis from P. guentheri Sauv., to which I 

 had first referred it. The latter differs in the shorter posterior 

 dorsal spines and the more truncate caudal fin.
