Among a collection of fishes, sent by Mr. Jackson Demery from Liberia, were 11 examples which, at first sight, seemed to me to agree with Hemichromis fasciatus Peters. A careful examination led me to give some remarks on the characters of this species, which will make the determination more easy, and contribute to resolve the question: do the examples of Hemichromis fasciatus, till now described by the authors, belong to one and the same welldefined species. The material of Hemichromis fasciatus now in the Leyden Museum, including the 11 above mentioned specimens, consists of a number of 28 examples, namely: a. N°. 2278. 3 spec., length 80, 115 and 125 mM. Dabocrom. Pel coll., 1850.
