The height of the body is contained seven times and a half in the total length, the 

 length of the head five times. The head is depressed, rather short, nearly as broad as 

 long; crown of the head broad and flat; interorbital space concave, narrower than the 

 orbit. Snout very short, obtuse, rounded ; the maxillary does not extend to behind 

 the posterior margin of the orbit ; lips thick. The teeth in the jaws form a band with 

 an outer series of stronger ones ; vomerine teeth in a narrow band ; palatine teeth 

 none. No orbital tentacles, those at the nostril and on the neck very small. Gill- 

 openings wide, the gill-membranes being united at the throat. Head naked ; scales on 

 the body not very small, cycloid. The dorsal fin commences at the occiput, and termi- 

 nates near the base of the caudal ; the spines are flexible, and much lower than the 

 soft rays ; the three anterior ones are rather more remote from one another tlian the 

 following : none of the rays of this or of the other fins are branched. Caudal rounded. 

 The anal is higher posteriorly than anteriorly, about as high as the spinous dorsal. 

 Pectoral rounded, with the middle rays longest, shorter than the head. Ventral s 

 jugular, half as long as the pectoral, with the spine and the outer ray enveloped in a 

 common thick membrane. Dark greyish olive ; head and fins blackish ; head, base of 

 the pectoral, anterior part of the body, and dorsal dotted with white. 



Several examples, of the size of the figure, were collected by Capt. Dow at Panama.

Body moderately elongate, with the scales small or of moderate size. Snout rather 

 short, with the cleft of the mouth of moderate Avidth. A band of small teeth in the 

 jaws ; teeth on the vomer. Two separate dorsals, composed of spines only ; the 

 anterior short, formed of three spines. Ventrals jugular, composed of three rays. 

 Head with tentacles ; gill-opening wide.
