HEMICHliOMIS TASCIATUS. 113 



Before meutiouing the conclusions I made after the study 

 of the literature , after the informations which came in from 

 other Musea , and after the material in the Leyden Mu- 

 seum , 1 will complete Peters' description. 



Prof. Hilgendorf at Berlin wrote to me , after examination 

 of the type-specimens , that as the sixth transverse band 

 is to understand the darker part above and below the 

 middle of the eye; the number of transverse bands on the 

 body is consequently five. 



The principal characteristics of Hemichromis fasciatus 

 are after Peters : 



1°. Five transverse dark bands on the body (the 



6th across the eye). 

 2°. A dark , bluish-black spot on the operculum. 

 3°. Both corners of the caudal fin white. 

 4°. Dorsal and anal fin with oblique dark and light 

 streaks, both with a white border, especially 

 the dorsal fin. 

 I add: 5°. Dorsal and anal fin sharply pointed, the middle 

 soft rays produced into short filaments. 

 I will now proceed to give a short review of what is 

 said in literature : 



Gill (1862) only repeats the description of Peters. 

 Giinther (1862), enumerating two specimens from West 

 Africa, says: »five or six blackish cross-bands; each scale 

 below the lateral line with a dark vertical streak." White 

 edges of the caudal fin are not mentioned. 



Bleeker (1863) describes the 5 specimens collected by 

 Pel; he states that there are 5 cross-bands, white corners 

 to the tail and »squamis mediis lateribus supra axillaribus 

 et interfascialibus aetate provectis singulis basi macula 



were collected at the Gold Coast and Ashantee , and Prof. Peters received from 

 the series of iJewiJcArow w-specimens two examples; the other 5 remained in 

 Leyden. These five have been described by Bleeker , whilst the drawing he 

 gives of Hemichr. fasciatus shows a combination of characters , not to be found 

 in one and the same individual.
