Length of head 3| to 4, of caudal 6t, height of body 4 in the total length. Eyes — diameter 5 in the 

 length of head, 2 diameters from end of snont, and 1:^ apart. Fins — pectorals short, two-thirds the length of 

 the head : caudal rounded. Scales — may be present or absent from the base of the dorsal fin. Colours — olive 

 brown, the body and caudal fin covered with blue black-edged spots : two or three rows of brown spots on the

Genus, 18 — Callyodon, (Qrouov.), Cuv. and Val. 



Body ohlong, rather compressed. Teeth in both jaws, anteriorly compressed and imbricated, being in one row 

 in the uppier and two in the lower jaw, whilst laterally they are soldered into one deep-cuttimj lamina : the inferior 

 pharynijeals, where the teeth (lohich are pavement-like) are present, broader than long. Anterior nostril with a 

 barbel-like prolongation. A single dorsal Jin with less spines (9) than rays (10) ; anal with two spines and less 

 rays (8) than the soft dorsal. Scales large: a single row on the cheeks. Lateral-line strongly bent or interrupted 

 below the posterior end of the dorsal jin. 



Geographical distribution. — From the Red Sea, through those of India to the Malay Archipelago, and

Length of head 3J, height of body 3 in the total length. Eyes — diameter 5 in length of head, li 

 diameters from end of snout. Teeth — no inner row in the upper jaw, but the outer tooth on either side is 

 recurved. Fins — caudal truncated. Scales — lower third of dorsal fin covered by them. Colours — vary
