194 SURGEON F. DAY ON NEW FISHES FROM MADRAS. [Mar. 12, 



Teeth villiform, with an external band of recurved ones ; a large 

 canine on either side of upper jaw near the mesial Hne ; and similar 

 teeth, but with smaller canines, in the lower jaw. Teeth in vomer 

 and palate in a recurved row. 



Fins. First dorsal one-third as long as the second, which is the 

 longest ; interspinous membrane shghtly emarginate. Second anal 

 spine strongest and longest. Caudal rounded ; ventral spine nearly 

 twice as long as highest in dorsal fin, and strongly serrated inter- 

 nally. 



Colours. Dark violet, with two bluish bands, one passing from 

 the lower margin of the orbit to the centre of the caudal fin, the 

 other from the summit of the orbit to the centre of the soft dorsal ; 

 anterior portion of the base of the dorsal white, also the interspinous 

 membrane between the fifth and seventh spines ; the rest of the fin 

 violet. Ventral yellowish. Caudal yellowish, with a vertical violet 

 band in its posterior third, whilst in its anterior half the violet bands 

 from the body cease, forming two large blotches.

Upeneoides c^ruleus, sp. nov. 



B. iv. T).7\l. P. 15. V. 1/5. A. 7. C. 19. L. 1. 32. 

 L. tr. 3/5. 



Length of specimens from lf\ to 3 inches. 



Length of head 1 of pectoral -j%, of caudal }, of base of first 

 dorsal ^, of base of second dorsal ^, of base of anal yL, of the total 

 length. Height of head ^ of body 5, of first dorsal |, of second 

 dorsal yV- of ventral f^, of anal -^ of the total length. 



Ei/es. Upper margin near the profile ; diameter nearly ^ of length 

 of head, 1 diameter apart, and the same distance from end of snout. 

 Form as in the other species. 



Maxilla broad at its posterior extremity, where it extends to beneath 

 the anterior third of the orbit. The barbies do not extend so far 

 as to beneath the angle of the prseoperculum. 



Teeth in fine villiform rows in both jaws, and in a single row in 

 vomer and palate. 



Scales. Ctenoid, eight rows between the two dorsal fins. 

 Lateral line in a single tube in each scale, which gives only one 

 branch from its upper side. 

 Air-bladder present. 



Coloui-s. Leaden superiorly, becoming dirty white below. The 

 first dorsal has a black tip, a widish light band along its centre, and 

 a badly marked one on its base. The second dorsal is darkish, with

 with black, and there is a band along the upper lobe. Pectoral, 

 ventral, and anal yellowish.
