 allied to F. bivittatus, Lonnb., and F. loennbergii y Blgr., but 

 differs from both in the more numerous anal rays. 



Haplochilus liberiensis. 



Depth of body 5^ to 6 times in total length, length of head 

 4 times. Snout a little shorter than eye, the diameter of 

 which is 3£ times in length of head ; lower jaw projecting 

 a little beyond upper ; interorbital width half length of head. 

 Dorsal 11, originating above fourth or fifth ray of anal and 

 sixteenth scale of lateral line, and at equal distance from head 

 and from root of caudal. Anal 15-16. Pectoral about § length 

 of head. Caudal rounded, nearly as long as head. Caudal

Two female specimens from Monrovia, Liberia, presented
