Scarus brunneus Jenkins, new species. Fig. 16. 
D. ix, 10. A. ii, 9. P. 13. V. 6. Head 3 in length to base of caudal; in total (to middle of 
caudal) 3.5. Depth 2.6 in length to base of caudal; in total (to middle of caudal) 3.1. Scales 24; 
lateral line interrupted, scales slightly roughened by striations of minute tubercles; tubes, some 
single, some once or twice branched. Body deep, compressed. Teeth whitish, a tooth at posterior 
angle of upper jaw ou one side in one specimen, the largest, none in 7 others. Upper lip double the 
whole length, broad, nearly covering dental plate; lower lip covering more than half of lower dental 
plate. Cheek with two rows of scales, 6 in upper and 5 in lower row; no scales on anterior limb of 
preopercle; a row of scales along margin of opercle; a series of 4 scales on median line before first 
dorsal spine. Dorsal spines flexible, spinous portion nearly equaling the soft portion in height; 
margin of caudal fin convex in the smaller specimens, with lobes not produced; lobes produced in 
larger ones; height of caudal peduncle 2 in head; pectoral 1.2 in head, its breadth about If its own 
length; ventral 1.9 in head, not reaching the vent by a distance equal to half the whole length of the 
fin, inserted on a vertical through the anterior point of insertion of base of pectoral. 
Coloration in life: Body, head, and vertical fins dusky-brown; pectorals and ventrals lighter; 
no distinct markings anywhere. This fish appears to be similar to Scams dnbius Bennett, whose 
description is very meager. In that given, it differs in not having scales on anterior limb of the pre- 
opercle, in having a pointed tooth at angle of jaw, in having 13 rays in pectoral, and in the caudal 
not being white on posterior edge.
