its height. Height 4 4.5, 5.3 6 in length with caudal. Head 

 3.9 4, 5 5.1 in length with caudal. Eye 3, slightly less than 

 postorbital part of head, which is about equal to interorbital 

 space. Snout somewhat shorter than eye, its upper profile 

 gently sloping downward in a straight line from eye to tip. 

 Teeth minute, conical, in several rows in the jaws; none on 

 the palate. Origin of anal below 6 th ray of dorsal. Origin of 

 dorsal separated by 27 scales from occiput, its distance from 

 first rudimentary rays of caudal equal to or a little more than 

 length of head. Ventrals reaching to about middle of anal, 

 longer than head ; their origin midway between base of caudal 

 and hindmargin of praeoperculum. Caudal deeply forked. Colour 

 dark above, silvery below. Pectorals dusky in their upper part, 

 hyaline in the lower part, reddish brown at the axil. Dorsal 

 and caudal dusky. Anal and ventrals white, the outer rays 

 of the latter somewhat dusky. Length 256 mm. 

 Habitat: Saleyer!; Aru Islands!. 



Note. This species is allied to C.bahiensis and C.oligolepis, 

 from both of which it differs through the absence of teeth 

 on the palate. It is moreover distinguished from C. bahiensis 

 by its greater height, smaller teeth, less blunt profile of snout, 

 and from C. oligolepis by its simple, not tricuspid teeth and 

 smaller scales.
