This is apparently the species which Theobald described 

 •as M, splendens, Wied,, in 1901. Although I have not seen 

 the specimen on which this description is based, it is evident 

 that the determination was erroneous, since Wiedemann states 

 that the tufts of the seventh abdominal segment in his species 

 are blackish. Through the kindness of Dr. H. Zerny, of the 

 Vienna Museum, I have recently been able to examine 

 Wiedemann's type ^ of il/. splendens. It proves to be iden- 

 tical with M. reg'ms (Tenuent), as might be supposed from 

 the description. 



LXVIII.— T/te Cichlid Fishes of Lakes Albert Edward and 

 Kivu. By C. Tate Regan, M.A., F.R.S. 



(Publislied by permission of the Trustees of the British Museum. ) 



Onl^ two or three species of Cichlidas are known from Lake 

 Albert, and these have also been found in the Bahr-el-Gebel. 

 Lakes Albert Edward and Kivu appear to have a more 

 interesting Cichlid fauna, each possessing a number of peculiar 

 forms of Ilaplochromis, which appear to be more nearly 

 related to species found in Lake Victoria than to those of 

 the ^'ile. 



Synopsis of the Genera. 



I. Scalea cycloid ; pharyugeal apophysis formed by parasphenoid alone. 



1. Tilapia. 



II. Scales more or less distinctly ctenoid ; pharyngeal apophysis 



formed by parasphenoid in middle and basioccipital at sides. 



Teeth conical, or outer bicuspid and inner tricuspid. 2. Raplochromis. 



An outer close-set series of enlarged teeth, with 

 strongly incurved, flattened, rounded crowns, 

 followed by 2 series of minute tricuspid teeth. . 3. Schubotzia.
