EDIBLE FISHES OF QUEENSLAND.— OGILBY. 79 



in considerable numbers by the ' ' Endeavour ' ' during August 1910, first off Pine 

 Peak, S.Q., and afterwards off Bowen, M.Q., which is at present the most 

 easterly station where it occurs, since it does not appear in Jordan and Seale list 

 of the fishes found in the Pacific Islands. 2 ' 3 It has not, so far as we are aware, 

 been recorded from the East Coast of Africa, nor has it been obtained in the 

 Indian Seas. We have, therefore, for this fish the extraordinary distribution 

 of five widely separated localities — Madagascar, the Seychelles, Java, China, and 

 Eastern Queensland — between which it is unknown. 



Uses: — -Valenciennes states that it is a very wholesome fish {tres-bon 

 poisson), and to us it certainly has every appearance of being a good food fish. 



Dimensions: — Both Valenciennes' and Kner's examples measured 11 

 inches, but the former remarks that it grows larger; Bleeker's largest example 

 of which we have cognizance was 350 millim. (about 13-8 in.) in length. 



Remarks: — Valenciennes' figure differs from our fish in several respects, 

 which may be briefly referred to here, even though some of them may be due 

 to the greater age of his specimen. For instance : our fish is considerably deeper 

 than his, being 245 in the total length {i.e. with caudal) as against 2-66 in his; 

 Bleeker's Batavian specimens are in some cases even more slender, the propor- 

 tional measurements being given as 2-66 to 3 in the length ; here again, how- 

 ever, we find that some at least of Bleeker's fishes were still larger than that 

 of Valenciennes, and we know that in other carangids (the two Alectis, Tri- 

 cropterus forstt ri } etc.) the law holds good — that the depth of the body decreases 

 with advancing age. Again both Valenciennes' and Bleeker's fishes were much 

 more robust than ours, their width being given as one third of the depth as against 

 one fourth in ours, a difference out of all proportion to the difference in actual 

 depth. Again the eve is much too small in Valenciennes' figure, being shown 

 along its greater diameter as but one fifth of the length of the head as against 

 34 to 3-75 in ours and 3-5 to 1 in Bleeker's. Valenciennes. Kner, and Gunther 

 give the number of dorsal rays as 1!>. but the former figures 20 as in my larger 

 example, while the latter has merely copied his predecessor; Bleeker inadvert- 

 ently omits all mention of the fin-formula' in the only paper to which Ave can 

 refer. Lastly Valenciennes' illustration shows nearly the whole opercle scaly, 

 which, is certainly incorrect as regards our fish. These differences, however, 

 are not sufficient to justify the separation of the two forms, unless future 

 investigation should prove them to be constant. 



CITULA AUROCHS sp. nov. 

 BLACK-CRESTED TREVALLY. 

 (Plate XXV.) 

 Type locality: — Edgecumbe Bay, M.Q. 



Body deeply ovate and strongly compressed, the dorsal and ventral 

 contours subsymmetrical ; width of body 4-25 to 4-5 in its depth, which is 1-8 to 

 1-9 in its length and about five sixths more than the length of the head ; abdominal
