Pornacentrus ( Dischistodus ) fasciatus Fowler & Bean, Bull. U. S. Nat. Mus. 100, vii, 1928, pp. 67 
& 111 (references). 
One from Moreton Bay presented by the Amateur Fishermen’s Association of 
Queensland. (Qld. Mus. Regd. No. 1.2189.) Klunzinger (1879) recorded this species 
from Port Darwin, but this is the first record of its occurrence in Queensland. Other 
specimens collected by J. Colclough at Dobo. Aru Islands, are in the A. F. A. Q. 
Museum, Brisbane (Nos. 1168-1169). 
The name Pornacentrus quadrifasciatus was evidently written on a drawing by 
Kuhl and van Hasselt, who collected the species in Java about a century ago. Their 
name, however, was not utilised by Cuvier & Valenciennes nor by Schlegel & Muller 
who described the species as Pornacentrus fasciatus. Kuhl & van Hasselt’s name was 
published in the synonymy of P. fasciatus by Bleeker (1877) and is a nomen nudum 
and an absolute synonym of P. fasciatus. 
Pornacentrus (Dischistodus) fasciatus var. intermedia Weber, 38 from the 
Philippine Islands, may apparently be maintained as a distinct variety.
