Description. — This species is allied to 0. gacliua, differing from it 

 by its longer caudal fui. The height of the body is contained seven 

 times in the total length, the length of the head four times. The 

 width of the interorbital space is much more than the length of the 

 snout, and two-sevenths of the length of the head. The cleft of the 

 month is of moderate width, the maxdlaiy extending to the vertical 

 from the pasterior margin of the orbit. 



The teeth on the vomer and the palatine bones stand in a single 

 series, and several of the former and of the lower are somewhat 

 larger than the rest. The scales on the upper surface of the head 

 are large, plate-like ; there are five series of scales between the e}'e 

 and the angle of the prieopercninm. The pectoral extends to the 

 origin of the anal fin, and its length equals the distance of the eye 

 from the end of the operculum, and is more than twice the length of 

 the ventral fin. Caudal somewhat pointed. Greenish-olive (in spirits), 

 ■\vith very indistinct small darker spots ; vertical fins Avith a whitish 

 margin ; pectorals dotted all over Avith greyish; ventral fins colouiiess. 



Length sixty-six lines.
