which is so conspicuous in the young of the western form, is wholly lacking in 

 the eastern. The segregation of the two forms under a varietal nomenclature 

 may. therefore, be advisable ; they would then stand as Caranx speciosus 

 speciosus (Forskal) and C. s. obtusiceps Macleay. 



Illustration: — Our figure is taken from a Darnley Island specimen in the 

 collection of the Queensland Museum. It measures 323 millim. and was the gift 

 of Dr. J. R. Tosh. Reg. No. I. 13/1097.

Type locality: — Cape Grenville, N.Q. 



Body ovate and compressed, the dorsal contour elevated and evenly 

 rounded from the frontal region to the peduncle ; ventral contour sublinear and 

 slightly declivous from the chin to the anal, whence it rises somewhat abruptly 

 to the peduncle ; width of body 2-55 in its depth, which is 24 in its length and 

 three tenths more than the length of the head ; abdominal region long, its length 

 1-15 in that of the anal fin ; depth of caudal peduncle 1-6 in its width, which is 

 1-25 in the eye-diameter. Head large, its length 3-1 in that of the body; width 

 of head 1-85 in its depth, which is subequal to its length; cranio-nuchal keel little 

 developed. fSnout rather long, its profile linear and strongly acclivous to the 

 level of the nostrils, above which there is an appreciable gibbosity, its length 

 3-05 in that of the head ; eye large, with the adipose lid little developed, its 

 diameter 3-8 in the length of the head and 1-25 in that of the snout; interorbital 

 region broadly rounded, its width about one eighth more than the eye-diameter. 

 Lower jaw projecting; maxillary extending to below the hinder border of the 

 pupil, its length 2-75 in that of the head, the width of its distal extremity 1-5 

 in its distance from the eye and half of the eye-diameter. Angle of preopercle 

 feebly erenulate. 



Upper jaw with a broad band of villiform teeth and an outer row of 

 enlarged widely set conical teeth ; lower jaw with a single series of strong 

 but rather smaller and more closely set teeth ; no perceptible canines ; small teeth
