large scales, a row along the base of the D., not much smaller 

 than those on the other parts of the body except some smaller scales 

 alongside the base of the A. The lateral line which is parallel 

 with the back to the region below the posterior D. rays, where it 

 is interrupted, traverses in this space 18 scales, it then appears 

 again on the antero-lateral region of the caudal peduncle and 

 traverses 5 or 6 scales, to the caudal. The tubes a})pear to be 

 single. The head, with the exception of the nasal, loreal, frontal 

 and labial regions naked, the rest covered with rather large scales. 

 Three rows of scales below the eye, the middle row with 6 and the 

 prseoperculum with 3. Scales on the opercles and cranium large. 

 General color greenish with the outer edges of each scale broadly 

 bordered with light green or yellowish. The D. with a longitu- 

 dinal bar, of lighter color than the green, which bifurcates near 

 the middle which results in an intervening bar of the greenish 

 color of the rest of the fin. A. similar to the D., but without 

 the median green bar. P, and V. greenish, their lower and inner 

 portions lighter. A bar, evidently reddish and bordered above 

 and below by a dark olivaceous band from the anterior margin of 

 the eye across the snout. Total length llf inches. 

 No. .23,291. 



10. Scarus lupus sp. nov. Plate XVIII, fig. 1 (upper figure). 



Form of the body oblong, elliptical, deep and compressed, the 

 greatest depth which is situated medianly about equal to the 

 length of the head and 3^- in the total length. Profile gently 

 convex from snout to origin of D. The eye is situated in the 

 upper portion of the head and nearly median, and in which it is 

 contained 6, and in the snout 2|, and in the postocular region 

 2|, and in the interorbital space 2 and in the greatest depth of 

 the head nearly 5 times. The greatest depth of the head falls 

 short of its length by an eye-diameter, though it is longer than 

 the P. by nearly the same distance. Snout very promiuent, the 

 beak large and powerful, the upper projecting beyond the lower 

 and with small denticulations which are rounded and do not form 

 a very sharp cutting edge. No lateral teeth at the bases of 

 either jaw like those of the preceding species and the lips thin 

 and covering the bases of .the jaws for a short distance only. 

 Head, with the exception of the nasal, loreal, prseopercular.
