teeth on each side of the upper jaw. The maxillary ter- 

 minates some distance in advance of the vertical from the 

 eye. The depth of the body is a little less than one half of 

 the total length (without caudal), the length of the head a 

 little less than one third. Eye two ninths of the length of 

 the head, much less than the length of the snout and than the 

 width of the interorbital space. Pectoral fin with the third 

 and fourth rays produced and extending to the first anal spine. 

 Caudal fin truncated, scaly. Body with indistinct cross-bands. 

 Vertical fins blackish, the dorsal with black longitudinal 

 stripes, longitudinal on the spinous portion, oblique on the 

 soft; a large oval black spot behind the last dorsal spine. 

 Ventrals black. A black opercular spot.

The height of the body is contained 1\ in the total length 

 (without caudal), the length of the head 2|. Length of the 

 snout equal to the diameter of the eye, which is one fourth of 

 the length of the head and equal to the width of the inter- 

 orbital space. Teeth conical, brown, equal in size. Four 

 series of scales on the cheek. Cleft of the mouth rather 

 narrow, slightly oblique, with the lower jaw slightly pro- 

 jecting and with the maxillary not quite reaching the vertical 

 from the front margin of the orbit. The length of the eighth 

 dorsal spine is two fifths of that of the head. In the adult 

 the soft dorsal and anal and the ventral fin are produced into 

 points. Brownish above, a deep black spot on the end of the 

 operculum and another in the middle of the body ; three or
