188 LÖNNBERG, NOTES ON FISHES COLLECTED IN THE CAMEROONS. 



Young specimens are provided with a black cross-band at 

 the base of the caudal fin, which is separated by two white 

 bands from two other black, but less sharply defined, cross- 

 bands, one descending from the origin of the adipose fin, the 

 other on the caudal fin. On one specimen, the tip of the caudal 

 fin is margined by a fourth black band. The smallest specimen, 

 only measuring 38 mm., has no black bands on the caudal fin. 

 The largest specimen, on which the black bands are conspicuous 

 measures about 17 cm. The younger specimens are much lighter 

 than the older, which have no white margin on anal and caudal 

 fins. Number of anal rays 9. 



Malapterurns benineusis is not mentioned by Steindachner 

 among Liberias freshwaterfishes and not by SCHILTHUIS among 

 Congos. GÜNTHERS specimens were from old Calabar. 



Haplochilus infrafasciatus GÜNTHER. 



One beautiful specimen from a rivulet with stony bottom 

 and clear water near ^he waterfall of the river N'dian. 



The carmine-red spöts or streaks on the scales, which Stein- 

 dachner has described in »die Fische Liberias» (1. c. p. 77), are 

 very bright and form 6 longitudinal rows. The blackish lateral 

 band (Günther) is not to be seen. The »six blackisch brown 

 crossbars» become gradually darker towards the caudal fin. The 

 first, second, third and fifth bands are double, or divided into two. 



Behind the eye is on each side a row of more or less ver- 

 tical carmine-red steaks extending to the upper hind margin of 

 the opercle. Another red band extends from eye to eye along 

 the margin of the forehead and the upper part of the nose. 

 Dorsal fin with carmine-red spöts. Caudal and anal fins not 

 speckled, but margined with black and red, pectorals and ventrals 

 not coioured, nor margined. 



Number of rays in the anal fin 17, it thus exceeds as weil 

 the number mentioned by Günther in the original description ^) 

 (14), as even the one (16) in Steindachners notes on specimens 

 from Liberia Cl. c. p. 77) Number of dorsal rays 11.
