HAPLOCHROMiS HGREI (Gunther) 



We have eight specimens, U.S.N.M. no. 84127, the largest 63 mm 

 in standard length, from Ujiji. They have the typical long snout, 

 spotted fins, and barred body of this species. Sometimes there is a 

 single longitudinal band, sometimes two or three. The dark spot 

 at the upper posterior corner of the opercle is plain in all, but the 

 oblique streak at the junction of the inter opercle and subopercle 

 and the spotting of the forehead are occasionally faint. Article 19 

 of the International Kules requires that the original orthography of 

 the specific name be retained.
