58 RECTIFICATION OF GENERIC NAMES. 



NOTE IX. 

 RECTIFICATION OF TWO GENERIC NAMES 



BY 



Dr. J. BÜTTIKOPER. 



I am sorry to say that amongst the new generic na- 

 mes, occurring in my recent paper on the genus Pyc- 

 nonotus and some allied Genera (N. L. M, XVII), Centro- 

 lophus and Gymnocrotaphus are already preoccupied among 

 the Fishes, the first being used by Lacépède, the second 

 by Günther. I propose, therefore, to substitute the name 

 Centrolophiis (pp. 226 and 230) by Bostrycholophus (curl- 

 crest) on account of the upward-bent longer crest-feathers, 

 and the name Gymnocrotaphus (pp. 227 and 245) by Bo- 

 napartia, Bonaparte being the author of the single species 

 of this peculiar genus.
