FISHES. MCCULLOCH. 159 



examination by Mr. E. R. Waite; these are figured in 

 the accompanying illustration. Though still very small, 

 the embryos indicate that R. vincentianus is identical 

 with R. banksii; the dorsal tubercles can only just be 

 traced but they agree in their disposition with those of 

 R. banksii, while the nostrils are disposed as in that 

 species. 



Localities. Ogilby (Joe. cit.) observed this species 

 in the trawl eleven times while the ''Endeavour" was in 

 Queensland waters. Specimens are preserved from the 

 following localities. 



Twenty miles off Bustard Head Light, Queensland, 

 20 fathoms; 8th July, 1910. 



Five miles S.E. of Boomerang Hill, Eraser Island, 

 Queensland, 15 fathoms ; 29th June, 1910.

Variation. Three specimens 265-273 mm. wide, 

 differ considerably in general appearance from a larger 

 470 mm. example which I have figured (loc. cit.), and 

 agree much better with Waite's figure quoted above. The 

 anterior portions of the ventrals are covered by the 

 pectorals in the smaller specimens, while they are fully 

 exposed in the larger one, which makes the latter appear 

 proportionately longer. The spiracles are less open in 

 the "Endeavour" specimens, and therefore appear 

 smaller. The exact shapes of the dorsal and caudal 

 fins are variable, as noted by AVaite, but they are 

 generally broader and rounder than in the larger
