XXXII. — The Classification of the Fishes of the Family 



Cichlidaj. — II. On African and Syrian Genera not 



restricted to the Great Lakes. By C. Tate Regan, M.A., 

 F.R.S. 



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



Since my paper on the Tanganyika Cichlidae (Ann. & Mag. 

 Nat. Hist. (9) v. 1920, p. 33), I have published revisions of 

 those of Lakes Edward and Kivu (Ann. & ]\Iag. Nat. Hist. 

 (9) viii. 1921, p. G32), of Nyassa (P. Z. S. 1921, p. 675), of 

 L. Victoria (P. Z. S. 1922, p. 157), and of ^ladagascar (Ann. 

 & Mag. Nat. Hist. (9) v. 1920, p. 422). There remain the 

 Syrian and African Cichlids outside the Great Lakes, and 

 it is the object of the present paper to give some account of 

 these.
