remainder are very little longer. The dorsal is connected with the caudal by a slight 

 membranous fold. The pectorals have twelve branched rays, and reach to the vent.

 three spines, the third being longest, and two-thirds of the length of the head. The 

 ventrals are connected with the body by a membranous fold. 



Colour uniform brown, fins marked with darker and lighter. Dr. Peters mentions a 

 spot on the lateral line, below the seventh and eighth dorsal spines, which is not visible 

 in our specimen. 



Length 5| inches.
