sixth of the total. The head is one-fourth less high and one-third 

 less broad than long. The width of the interorbital space is one-half 

 of the diameter of the eye. Scales large ; teeth small. The fifth 

 dorsal spine is the longest, filiform ; the other fins pointed pos- 

 teriorly. YeUowish-brown, clouded with darker ; a bluish line from 

 the eye to the angle of the mouth ; dorsal fins mth gre^-ish longi- 

 tudinal lines ; the upper part of the caudal and the anterior margin 

 of the dorsal fins dotted with black and white. (Val.)

Nino longitudinal series of scales between the second dorsal and 

 the anal fins. The height of the body is contained eight times in 

 the total length, the length of the head four times and a half; the 

 head is depressed, broader than high ; the snout elongate, broad, 

 flat, with the lower jaw prominent. Several teeth of the outer series 

 are enlarged, canine-Uke, but there are no lateral canine teeth. 

 The width of the interorbital space is more than the diameter of the 

 eye, which is one-sixth of the length of the head. The distance of 

 the first dorsal from the eye equals that of the snout from the prae- 

 opercular margin. Head naked; scales on the nape of the neck 

 smaller than those of the body. Dorsal fins higher than the body ; 

 the spines of the first are produced into filaments, and the second 

 and third are the longest. Caudal elongate, obtusely pointed, one- 

 fourth of the total length ; none of the pectoral rays sLLk-Kke ; ven- 

 tral with the basal membrane well developed. Yellowish-brown, 

 with indistinct blotches along the side ; dorsal, caudal, and pectoral 

 fins brown-dotted.

The natural affinities of this species are to O. c/iuris, from which 

 it is readily distinguished by the extraordinaiy development of the 

 caudal fin.
