54 ANNALS OF THE QUEENSLAND MUSEUM. 
Described from 7 examples, measuring between 121 and 197 
millim., obtained by Mr. John Colclough, at Dobo, Aru Islands, and 
by him presented to the A.RA.Q. Museum. Oat. No. 1170. 
Just twenty-five years ago Mr. De Vis, under the name Apistus 
caloundra, described a new Queensland fish from the Moreton 
District. Of the differences between his species and the typical 
Apistus (alatus) he writes — " To these, the fish now brought under 
notice is closely allied ; and, notwithstanding that it differs in two 
structural features of some importance — namely, in having but 
fourteen spines in the dorsal fin, and the pectoral reduced to a size 
unfitting it for an organ of flight — I refer it to the same genus 
Apistus because it appears to me preferable to relax somewhat the 
character of a genus founded on two species only, rather than 
burden the system with a new one, which does not seem necessary." 
There are, however, other differences which seem to me to 
justify generic recognition, which I therefore accord to it under the 
name 
APISTOPS gen. nov.
