170 MR. J. Y. JOHNSON ON NEW GENERA AND SPECIES [June 10, 
sharp teeth curving backwards ; and the pharyngeals are armed with 
scobinate bands of teeth. The inside of the mouth is black, as well 
as the tongue, which is small, toothless, and free at the tip. The 
gill-openings are side by side on the ventral aspect of the body, in 
advance of the pectoral fins; they are separated by a membrane 
placed inside a single external aperture. The dorsal fin commences 
behind the vent, a little posterior to the commencement of the second 
third of the total length, and joins the caudal, like the anal fin, 
without a break. It is higher behind, but is throughout much lower 
than the anal; the greater part of it is covered with a scaly skin, as 
is also the greater part of the anal fin. The pectoral fins are well 
developed, pointed, and situate a little behind the gill-openings, 
below the middle of the height. The ventral fins are wanting. The 
vent is in the first third of the total length. The anal fin commences 
just behind the vent ; it is considerably higher about the middle and 
behind than in front. The caudal is rounded. The lateral line is 
distinctly marked; it falls gently from the shoulder, but for the 
greater part of its length is straight along the middle of the body. 
The air-bladder is long, being more than one-third of the length of 
the body. The food found in the stomachs of dissected specimens 
consisted of the remains of fishes and crustaceans. The peritoneal 
lining is of a dark-blue colour. 
Dedicated to Dr. Kaup of Darmstadt, who has well studied this 
order of fishes. Specimens have been sent to the British Museum.
