D. 6/11, A. 10. A small fish, two inches long, and in an indifferent state of preser- 

 vation, seems to be a second species of this genus, having the same singular dentition as 

 Lentipes concolor, but the tail is covered with small scales, the head and trunk only being 

 naked. It is an adult specimen, the ovaries being fuUy developed. The eyes are small, 

 situated in the anterior half of the lensrth of the head. The lenoth of the head is one- 

 fourth of the total, the caudal not included. The vent is somewhat nearer to the root of 

 the caudal than to the head. Length of specimen, 2 inches. Honolulu, fresh-water.

D. j%, A. ^x» L. lat. 29, L. transv. 3-^/10. The determination of this species is 

 rather doubtful, as it seems subject to great variation of eoloiu-, unthout being distin- 

 guished by some striking and constant peculiarity. There are four specimens in the 

 collection, three of which are young, and the fourth apparently adult. The dorsal spines 

 are remarkably short, and the upper and lower caudal lobes produced into short filaments. 

 In the young the body is of a brownish- violet colour, which extends sometimes over the 

 whole caudal fin, sometimes stopping short at the base of that fin, leaving it white. 

 Scales with or without an indistinct vertical purplish line. Head apparently without 

 markings. Dorsal and anal fins uniform blackish, or if of a lighter colour, with a 

 black spot between the three anterior spines. Pectoral fin -nith a black spot superiorly 

 at the base, and with a broad black longitudinal band, which sometimes becomes in- 

 distmct. 



The adult has the ground colour light reddish, only the end of the tail, and tlie up])cr 

 and lower margins of the caudal being Uack. Each scale with a vertical purple streak. 

 Dorsal and anal fins greyish, without black spot in front. Pectoral liglit yellow, without 

 black band, and without axillary spot. Length of specimen, 4 to 7 inches. Honolulu.
