66 MEMOIRS OF Till. QUEENSLAND MUSEUM. 



Hit-in respectively from Sumatra, Nias, Singapore, Banca, Java, and Celebes 

 para and Java and Madura (cambon). 



Dimensions: — II is rather difficult to say 1<> what size this species really 

 grows; of the 52 examples obtained by the "Endeavour" the largest does not 

 exceed 190 millim. Valenciennes notes the length of his specimens as to about 300 

 millim., while Day complicates the matter by stating in 1865 that it attains a 

 length of over 600 millim., but eleven years later reduces that measurement by 

 two thirds, without making any explanation of the discrepancy. Probably 

 Valenciennes' computation may be taken as the most correct. 



Illustration: — Taken from a Queensland specimen, 182 millim. in length, 

 now in the State Museum. Reg No. 1. 14/2233.

Body subovate to ovate, compressed. Scales small and cycloid, covering the 

 whole body except the nuchal ridge. Lateral line with along and gentle curve, the 

 scutes few and weak. Head rather large, compressed, with convex profile and 

 long rounded snout, the cheeks, temples, and occiput mostly scaly. Mouth 

 terminal, protractile, with moderate oblique cleft, the upper jaw the longer; 

 maxillary rather short, dilated distally, its upper edge covered by the mem- 

 branous herder of the preorbital : supplemental hone well developed. Young 

 with minute teeth, which wholly disappear with age. Nostrils small and con- 

 tiguous. Eyes small, lateral, median, the adipose lid little developed. Preopercle 

 entire, the border membranous. Spinous dorsal low, with 8 feeble spines, some 

 of which are absorbed in the adult; soft dorsal and anal with moderate equal 

 lobes, the former with 18 to 21, the latter with 15 to 17 soft rays; anal spines 

 small. Caudal deeply and widely forked. Pectoral long and falcate, with 22 

 rays. Venlrals moderate, originating below lower angle of pectoral-base. Gill- 

 rakers well developed and rather stout, in moderate number. (From the 

 French name "carangue," which is said to be a corruption of the Portuguese 

 '• acarauna.") 11 



Fishes of moderate size, inhabiting the warmer waters of the Indian and 

 Pacific Oceans. Two, perhaps three, species recognisable. 



The main differences between C. ruppellii and C. speciosus are as follow: — • 

 a 1 . ELead about 4 in total length; maxillary extending to below anterior border of eye or not 



quite so far speciosm. 



tr. Head about 5.07 in total length; maxillary extending to below or beyond middle 



of eye ruppellii?" 



11 Similarly our vernacular name "trevally" is undoubtedly a corruption of the Spanish 

 ' ' cre\ a IN'. ' '
