fin with usually less spines (9) than rays (9-12) ; anal with two or three spines, and rays nearly similar to those of 

 the dorsal (9-10). Scales on body of moderate size, they a/re extended over the operdes, cheeks and base of the vertical 

 fins : no enlarged row at base of caudal fm. Lateral-line contiimous. 



Geographical distribution. — Red Sea, seas of India to the Malay ArcHpelago.

Length of head 3i to Si, 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 1| 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 third of the base of the caudal fin when it bends sUghtly 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 Elhot's collection : the figure is taken from one of them. My Andamanese specimen has twelve dorsal 

 rays, the last beiag 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 — Cheblinus, (Lacep.) Ou/vier. 



Ozycheilinus et Grassildbrus, GUI. 



Branehiostegals five. Body oblong, compressed. Preopercle entire. Lower jaw not produced backwards. 

 Teeth in one row, two canines in either jaw, none being directed outwards : no posterior canine: inferior pharyngeal 

 teeth not confluent or pavement-like. 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) tha/n those of the dorsal. 

 Scales la/rge (20 to 23 in a longitudinal row), two roivs on the cheeks, the last three at the base of the caudal fin 

 enlarged. Lateral-line interrupted. 



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

 Archipelago, China, and beyond.
