Length of head 3f , of caudal 7J, height of body 3J in the total length. Hyes — diameter 6 in length of 

 head, '2 diameters from end of snout and also apart. Upper lip broad. Teeth — each jaw with 2 small ones at 

 the corner.* Fins — the anterior dorsal spines rather shorter than the succeeding ones : caudal rather 

 truncated. Scales — ^two rows on the cheeks, and two scales on the lower limb of the preopercle, the lower row 

 on the cheek consisting of six scales. Colowrs — green, each scale with a reddish base. Snout and cheeks with 

 numerous undulating green lines, its ground colour reddish. A narrow green band along the base and edge of 

 the dorsal fin, with an intermediate row of spots : anal green, becoming lighter towards its margin, which is 

 edged with dark green : caudal with green spots. The specimen figured, variety EMSsellii, was sea green, 

 each scale, except those on the chest, having a semilunar reddish base equal to about half its width : the scales 

 between the bases of the ventral and anal fins reddish : head rosy : a few short blue lines radiate from the lower 

 edge of the orbit i anteriorly one passes to, the upper edge of the lip, which it skirts : another goes to its lower 

 margin, which it encircles. Dorsal fin reddish, superiorly edged with light blue , a row of green spots along its 

 centre, and another at its base -. caudal reddish, with four or five vertical bluish-green bands : anal similar to 

 dorsal : pectoral and ventral reddish, the outer ray being blue : eyes hazel. 



Habitat. — East coast of Africa, through the seas of India to the Malay Archipelago and beyond. The figure 

 is from a stuffed specimen (a female, 18, inches long) captured at Madras, July 12th, 1868.

Length of head Z\, of caudal 8, height of body ^ to 3^ in the total length. %es— diameter 4^ to 5f 

 in the length of the head, li to 2 diameters from the end of snout, and 1^ apart. Upper lip broad. Teeth— 

 free margins with crenulated edges, and in the adult a conical tooth at the angle. J'm*— dorsal spines subequal 

 in length. Caudal rounded. Scales — two rows on the cheeks, the lower of which is not extended over the 

 lower limb of the preopercle. Colours— oi a purplish brown, the edges of each scale being darker than their 

 centres, the large scales covering the first 2/3 of the caudal fin dull yellowish, a violet tint in the thoracic region 

 where the centres of some of the scales are of a light colour. Snout greenish-yellow. Vertical fins brown, the 

 dorsal with a narrow black outer margin. Pectoral transparent. 



Habitat.— Eiast coast of Africa; Andamans to the Malay Archipelago. One specimen 27 mches long was 

 taken at Port Blair.
