704 MR. F. DAY ON NEW INDIAN FISHES. [June 27, 



fringed externally. A short distance external to the posterior nos- 

 tril is a sharp spine, leading backwards from which to above the 

 angle of the prseoperculum is a spiny ridge containing five more 

 directed backwards. Along the angle and lower border of prseoper- 

 culuni are three denticulations — the superior a strong spine, the 

 others blunted ; there are also three flesh}' tentacles along its border, 

 and one on the side of the praeoperculum. Interoperculum with a 

 blunt spine and tentacle. Operculum with a bony ridge along its 

 centre, ending in two spines. A ridge containing three spines passes 

 from the posterior inferior margin of the orbit to the upper margin 

 of the opercle and commencement of the lateral line, and has two 

 minute spines below it. Another spiny ridge extends from the pos- 

 terior superior margin of the orbit backwards, and one spine between 

 it and the ridge below it. Orbit with a strong spine at its anterior 

 superior margin, one at its posterior superior margin, and one at its 

 superior margin, which has attached to it a long wide tentacle on a 

 narrow base. Several fleshy tentacles exist along the edge of the 

 snout, a large one above the angle of the mouth, and two on the 

 extremity of the upper jaw ; there are also three rather large ones 

 on the lower jaw. 



Teeth viUiform, in numerous rows in both jaws, also in a V-shaped 

 patch on the vomer, but none on the palate. 



Fins. Dorsal spines moderately strong, the third the longest ; 

 interspinous membrane rather deeply cleft, and extended beyond 

 each spine. Pectoral broad at its base, its twelve lower rays un- 

 branched, and minute fleshy appendages attached to them. Ventral 

 spine strong. Anal — first spine short, second and third of equal 

 length, but the second twice as strong as any in the fish. Caudal 

 cut square at its extremity. 



Scales in rows proceeding backwards and upwards. Some on the 

 upper part of the operculum ; head otherwise scaleless. 



Lateral line in twenty-three or twenty-four tubes. 



Colours. Of a general rose-colour, marbled with greyish ; the 

 spines on the head are darker than the surrounding parts. One or 

 two irregular grey bands with dark edges exist on the tail. The 

 dorsal and anal are also banded ; and the pectoral has numerous 

 bands on it. 



This species differs from the S. venosa, C. & V., which has no 

 orbital tentacle, and of which the third anal spine is the longest and 

 strongest, and the caudal fin is rounded, &c. 



Caranx nigrescens, sp. nov. 



B. vii. D. 7/^. P. 19. V. 1/5. A. 2/^. C. 19. L. 1. 25.

 of base of second dorsal i, of base of anal -I, of caudal | of the total 

 length. Height of head |, of body i-, of first dorsal yV, of second 

 dorsal g, of ventral jttj of anal g of the total length. 



i^yes with very narrow adipose lids ; diameter 4 of length of head.
