light band from the opercular flap to the caudal rays and directly 

 below this, and parallel to it, starting from the P. region, is an- 

 other similar band. Longitudinal stripes along D. and A. , longi- 

 tudinal stripes along the inner of the pi'oduced caudal rays and the 

 l)asal half of the rest of most the caudal rays of the same color 

 as the lateral stripes. With the exception of a thoracic stripe 

 from the interoperculum backward the body is bright green. 

 Length about llf inches. The specimens which I refer to this 

 species show considerable color variation, which may be due to 

 individual variation. There are three specimens, one of which is 

 very young.

SCARID^. 

 9. Scarus pronus sp. nov. Plate XVIII, fig. 3 (lower figure). 



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

 greatest depth more or less in the centre and apparently greater 

 than the length of the head which is contained in the total length 

 about 4^ times. Eye not quite 6 in the head, about 2f in snout, 

 in postocular region 2^ and in the interorbital space twice. 

 The greatest depth of the head is inferior to its length and the 

 upper profile line from the tip of the snout to the interorbital 

 space moderately convex, and from this latter point to the occiput 

 with a very strong convex appearance foi'med by the elevation of the 

 supraoccipital ridge. Snout produced, mouth small and with lateral 

 canine-like teeth, projecting externally, at the angle, there is one 

 on each side of the upper and two similar on the lower. The jaws 

 which are modified into a beak, which is small, have the teeth 

 small, at present whitish, and the lips appear to have covered the 

 greater portion. Origin of the P. below the level of the eye, 

 directly above that of the V., radii ii, 12, shorter than the head 

 and equal to the base of the P. V, 1^ in P., radii i, 5, much 

 stronger than P. Origin of the D. a little behind that of the P. 

 and v., radii ix, 10, the spines rather firm, though they may 

 have been more or less pungent during life, and together with 

 the soft rays of uniform size. A. ii, 9, the soft rays of the D. 

 similar and the tips of both not much if any produced beyond a 

 point. Caudal rays strong, the outer produced into points thus 

 leaving the posterior edge deeply incised. Body covered with very
