Description of the specimen. — The body and the head are slightly 

 compressed and somewhat elongate ; the height of the body is five 

 times in the total length, the length of the head (without opercular 

 spine) Sf. The upper svu'face of the head is smooth and rather flat, 

 with a pair of slight ridges between the orbits ; the width of the 

 sjiace between the orbits is rather less than the diameter of the eye, 

 which, of moderate size, equals the extent of the snout. The oper- 

 culiun is armed with a long straight spine. The two dorsal fins are 

 separated from each other and, like the anal, of moderate height; 

 the spines of the first are flexible. The caudal is subtnmcated ; the 

 pectoral large, rounded, with the five lower rays simple, and thicker 

 than the upper ones. The ventrals also are rather elongate, and 

 reach to the vent ; they are composed of one spine and five rays, and 

 are rather remote from each other. There is no scale visible ; the 

 lateral line appears to be rough. Teeth are perceptible in the jaws and 

 on the vomer, whUst the existence of those of the palatine bones can 

 only be perceived by the touch. The colour is uniform bluish-olive. 



Total length 20 lines.
