512 CICHLID^E. 



A male specimen sketched from life by Mr. Degen is represented as pale lilac above, 

 bluish grey beneath ; sides with bars of emerald-green ; the anal fin was pink, with 

 four orange spots encircled with carmine-red and with a red centre ; ventral fins of a 

 dark steel-blue, the outer rays black. 



H. nuchisguamulatus does not appear to exceed a length of 125 millimetres. 



This species was discovered by the late Dr. G. A. Fischer in Lake Victoria. Seven 

 specimens from Entebbe (2.6.05) and one from Bunjako (5.11.05) are in Mr. Degen's 

 Collection. I have also examined two specimens from the Buddu coast of the lake 

 (Coll. Simon, 1906). Young specimens from Kavirondo Bay (Coll. O. Neumann, 

 1894) appear to have been correctly referred to this species by Hilgendorf. 



Dr. Pappenheim has been so kind as to send me excellent photographs of the type 

 specimens of C. nuchisguamulatus, obliquidens, and sanvagei, preserved in the Berlin 

 Museum, w 7 hich confirm the opinion previously formed by me that these three supposed 

 species must be reduced to one.
