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 than 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. Ventrals 
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. 
CREMNOBATES. 
Cremnobates, Giinth. Proc. Zool. Soc. 1861, p. 374. 
Body moderately elongate, with the scales small or of moderate size. Snout rather 
short, with the cleft of the mouth of moderate width. A band of small teeth in the 
jaws; teeth on the yomer. 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.

A fimbriated superciliary tentacle ; a small one at the nostril and on each side of 
the nape, both multifid. A black ocellus, edged with white, on the posterior quarter

Specimens, 2 inches long, were collected by Capt. Dow at Panama.
