From the above given notes can be seen that this species is 

 variable as weW in colour as in other characteristics. 



Haplochilus infrafasciatus is a West African species. From 

 West Africa and Upper Nile another species of Haplochilus is 

 described by Günther under the name Haplochilus fasciolatus 

 (1. c. p. 358). The measurements of H. infrafasciatus and H. 

 fasciolatus are nearly the same. According to the description.> 

 and diagnoses almost the only diflference in measurement is, that 

 the snout of H. fasciolatus is comparatively a little longer than 

 that of H. infrafasciatus. But Steindachner has shown that 

 the relative length of the snout varies so that it can be con- 

 tained from 2^/2 to 3 times ^) in the length of the head in H. 

 infrafasciatus. The same is also the case with the diameter of 

 the eye which is ^/i — ^/s of the same length. Haplochilus fasci- 

 olatus is said to have somewhat longer pectorals, so that they 

 reach beyond the root of the ventrals, but this can hardly be 

 regarded as a specific character. The coloration and number of 

 anal rays are varying:

The red streaks on the scales are to be found on Stein- 

 dachner's specimens of H. infrafasciatus, Günther's of H. 

 fasciolatus and the above described specimen from the Came- 

 roons. Steindachner found dark crossbars on both sides of 

 three, and on one side of one specimen; on the other side of this 

 specimen was a longitudinal band as Günther mentions in the 

 diagnosis of H. infrafasciatus. The crossbars of the species from 

 the Cameroons are already described. The typical H. infrafas- 

 ciatus ought to have »six blackish-brown crossbars», the typical 

 H. fasciolatus »eight or nine oblique narrow bronwnish streaks, 

 descending from the middle of the side forwardsv. If we consider 

 the variability that already is stated, it does not seem impossible
