 the dorsal (9-10). Scales on body oj moderate size, they are extended over the opercles, oheelcs and hase of the vertical 

 fins: no enlarged row at base of caudal fin. Lateral-line continuous.

Lensjth of head SJ to 3J, of caudal 5, height of body 3^ to 4 in the total length. Eyes — diameter 1/4 

 of length of head, 1 diameter from end of snout, and 1^ apart. Opercles entire. The lips emarginate 

 anteriorly. Height of head equals about If in its length. Fins — third anal spine the longest: caudal 

 cut square. Lateral-line — curves opposite the posterior end of the dorsal fin. Colours— nearly white, with a 

 black band through the eye to the upper thii-d of the base of the caudal fin when it bends slightly to reach the 

 centre of that fin: a black band along the anal, which passes to the caudal and joins the upper _ band 

 at the end of that fin : a dark band along the dorsal fin. Two specimens, captured at Waltair, exist in Sir 

 Walter ElUot's collection : the figure is taken from one of them. My Andamanese specimen has twelve dorsal 

 rays, the last being divided into two : it has also two posterior canines in either jaw. 



Habitat. — Red Sea, Coromandel coast of India, Andamans to the Malay Archipelago. 



Genus, 4 — Cheilincs, (Lace'p.) Cuvier. 



Oxyclieilinus et Crassilabrus, Gill. 



Branchiostegals five. Body oblong, compressed. Preopercle entire. Lower jaw not produced baclnvards. 

 Teeth in one roiv, two canines in either jaw, none being directed outwards : no posterior canine : inferior p)har]jngeal 

 teeth not confluent or paveinent-lilce. A single dorsal fin, the number of spines (9-10), being about equal to the rays 

 (9-11). Anal with three spines, the third being the longest, its rays rather less (8-9) than those of the dorsal. 

 Scales large (20 to 23 in a longitudinal rOw), two rows on the cheeks, the last three at the base of the caudal Jin 

 enlarged. Lateral-line interrupted. 



Georiraphical distribution.— Ucd. Sea, and east coast of Africa through the seas of India to the Malay 

 Archipelao-o, China, and beyond.
