The heiglit of the body is contained tlirce times, the licad 

 four times in tlie total length. Tlie diameter of the eye nearly 

 equals the length of the snout, and is contained three times 

 and two thirds in tlie length of the head. The snout is rather 

 sliort ; the cleft of the mouth moderate ; the maxillary ex- 

 tends to the front margin of the orbit. Prieoperculum slightly 

 sinuous posteriorly. The dorsal is deeply notched ; the fourtli 

 spine longest, it is contained once and two thirds in the length 

 of the head. Caudal slightly concave. Second anal spine 

 very long and strong, longer than the fourth dorsal. Pectoral 

 nearly one fourth of the total length. Silvery, the upper two 

 thirds with brownish dots. Dorsal fin with a series of brownish 

 spots along its base ; dark spot on the opercle. 



Two specimens from the Cameroons. The largest is 

 7^ inches long. 



Percis caudimaculatum.

The height of the body is contained seven times, the length 

 of the head four times and a half in the total length. The 

 diameter of the eye is twice the width of the interorbital space. 

 The prteoperculum is slightly denticulated. The ventrals do 

 not reach to the origin of the anal. The central spines of 

 the dorsal fin are the longest. Body with six vertical brown 

 bands, interrupted by a lighter longitudinal line j a black 

 sjjot at the upper angle of the root of the caudal. 



Four specimens from North China. The largest is 4| inches 

 long.

The height of the body is contained four times or four times 

 and a third in the total length, the length of the head about 

 four times ; the diameter of the eye is contained four times 

 and a half in the length of the head. The length of the snout 

 scarcely exceeds the diameter of the eye ; it is slightly convex, 

 with the jaws neardy equal in front. The u[)per maxillary 

 reaches to the vertical from the posterior margin of the orbit. 

 The upper jaw has an outer series of larger teeth. The praj- 

 operculum is rounded, finely denticulated ; the operculum has 

 two points. Caudal pointed. Anal spine feeble, one fourth 

 of the length of the head. Coloration (in spirit) uniform 5 u
