186/.] SURGEON F. DAY ON NEW FISHES OF MADRAS, 937 



The posterior extremity of the maxilla extends nearly as far as to 

 beneath the anterior margin of the orbit. The posterior limb of the 

 intermaxillaries extends to opposite the anterior margin of the orbit. 

 Praeorbital two-thirds as wide as the orbit. Prseoperculum a little 

 emarginate, its angle slightly produced, serrated in its whole extent, 

 but coarsest at the angle, the lower limb two-thirds as long as the 

 vertical one, and with some few serrations along its posterior part. 



Teeth villiform, in several rows anteriorly, becoming a single one 

 posteriorly, some also on vomer and palate. 



Fins. Dorsal spines strong, every alternate one broadest, inter- 

 spinous membrane slightly emarginate ; fourth spine the longest ; 

 last spine three-fourths as high as the first ray. Pectoral pointed. 

 Ventral spine not very strong, its first ray with a short filamentous 

 prolongation. First anal spine weak, and one-third as long as the 

 second, which is strong and one-fourth longer than the third, which 

 is striated anteriorly and laterally, and has a smooth keel anteriorly 

 half the width of the spine. Caudal slightly lunated. 



Scales in horizontal rows, except to the first seven dorsal spines, 

 to which they ascend irregularly upwards and backwards. There 

 are some fine scales between the dorsal and anal rays. 



Lateral line follows the course of the back. 



Colours. Greyish, becoming white along the abdomen. A brilliant 

 yellow band passes along the centre of a row of scales from opposite 

 to the centre of the orbit to the centre of the base of the caudal fin. 

 A similar one passes a short distance along the centre of the row above 

 it. Dorsal and caudal fins greyish, soft dorsal with a light margin. 

 Pectorals, ventrals, and anal yellowish. Eye golden. 



I have named this species after mv esteemed correspondent A. C. B. 

 Neill, Esq., F.Z.S. 



Pristipomoides aurolineatus, sp. nov.

 L. tr. 8/16. 



Length of specimen 3y\j inches. 



Length of head -^j, of pectoral i, of base of dorsal spines 4-, of base 

 of dorsal rays ^, of anal -^j, of caudal ratlier above J- of the total 

 length. Height of head 4-, of body |, of dorsal spines j^, of dorsal 

 rays j-V, of ventral ^, of anal spines jjj, of anal rays jrj of the total 

 length. 



Eyes circular, upper margin close to the profile, diameter -i. of 

 length of head ; f of a diameter apart, ^ a diameter from end of snout. 



Body rather elongated and compressed; head slightly depressed. 



Mouth anterior, lower jaw the longest ; posterior extremity of the 

 maxilla rather wide, extending to beneath the anterior third of the 

 orbit ; the posterior limb of the intermaxillaries likewise extends back- 

 wards in the central line to opposite to the same place. Prasorbital 

 long, narrow, and at least three times as long as wide, and with ele- 

 vated striae upon it. Prseoperculum wide, its horizontal wider than 

 its vertical limb ; both striated at their edges, and irregularly serrated.
