363k. C. CASTLEnaui. Monacanthus peronii Castlenau P.L.S. N.S.W. iii., 

 1879, p. 398 (not M. peronii Hollard). M. castlenaui Macleay, P.L.S. 

 N.S.W. vi., 1881, p. 316— substitute name. 



The few characters given in Castlenau's paper are insufficient for the re- 

 cognition of this species. It is doubtless synonymous with one of the preceding 

 species. 



(C. platifrons Hollard, has been incorrectly included in New South Wales 

 lists on the authority of Gunther, Brit. Mus. Cat. Fish, viii., 1870, p. 229, who 

 erroneously gave New South Wales as the locality of the holotype instead of 

 King George's Sound. 



C. convexirostris Gunther was included without comment in a mere list of 

 New South Wales fishes by Castlenau, but it has not since been recognised from 

 these waters).
