spinous ridges ; those on the opercles, and on the series between the 

 occipital and postorbital ridges with 3 to 7 spinous ridges. First 

 dorsal spine concealed (sharp in the smaller specimen). Fifty pyloric 

 caeca, shorter than the orbit. 



C. tohiensis is probably most closely related to C. mdcrorhynchus 

 Smith and Radcliffe/ a Philippine species, and to C. quadrlcrlstatus 

 (Alcock),- an Indian species. From C. macrorhynchus^ it diifers in 

 the absence of scales on the under side of the head, excepting the 

 definite small posterior patch ; the dark bars of the body ; the blunt 

 snout ; and the shorter interdorsal space, which is shorter, instead of 

 longer, than the base of the first dorsal. From G. quadrlcristatus^ it 

 differs in the shorter blunter snout; the larger eye; the naked under- 

 side of head ; in the more numerous pectoral rays, 18 or 19, instead of 

 16 ; and in the ventral extension of the dark bars to the anal base. 



TaUe of measurements in linndredths of length to anus.
