longitudinal band more distinct and possessed in addition a narrower band 
along the entire lower edge of the body to the caudal. Back violet brown ; 
bands separated by yellowish. A brownish band around the lower jaw | 
toward the eye. Dagana, Senegal. (Steindachner.) 
Apart from the red markings of the scales, which belong to the sexually 
mature or the nuptial season, there seems to be little reason for the separa- 
tion of H. chaperi, from freshwater in the lagoon “ d’Assinie, & Couacrou,” 
in the gold coast region.

This apparently is a variety of HZ. senegalensis. The locality given is Bahr 
el Seraf and Bahr el Gebel.

The differences by which this form is distinguished from the preceding 
are mainly in the coloration: it has a couple of streaks of brown from the 
orbit to the base of the caudal and another from the lower edge of the base 
of the pectoral along the base of the anal and the lower edge of the caudal. 
I am inclined to place it as a variety of HZ. senegalensis with H. Marnoi from 
the same locality.
