If this form is compared with Dibranchus atlanticus Pet. it will not 
only be seen that there is a certain degree of resemblance, but that the 
present species is narrower and less angular on the head, and has much 
finer tubercles and a much smaller subopercular process. Body and head 
forming together a much depressed subcircular disk about as wide as 
long; tail distinct, narrow, rounded, tapering from the vent. Greatest 
depth of the head nearly one third of its greatest width, top moderately 
prominent above the balance of the disk but not angular except around 
the edge at the top of the snout; length of the head to the gill open- 
ings less than one length of the orbit shorter than the distance from 
the snout to the vent. Snout short, lower jaws longer, top slightly con- 
cave with erect tubercles around the edge, deeply excavated below the 
rostrum for the club-shaped, trilobed, protractile illicium. The movement 
of this organ as a whole is forward and back, but the fleshy esca can 
be thrown forward at the top somewhat like the tongue of a frog. The 
lateral lobes of the esca are rounded ; the median lobe is slightly notched, 
the notch being due in part to a folding inward of the edges of the 
bulb. Nasal sacs anterior, prominent, near the illicium, directly forward 
of the eyes; nostrils small, close together, posterior subcrescentic, anterior 
smaller with a short bell-shaped tube. A prominent tubercle above each 
angle of the mouth. Mouth medium, anteriorly somewhat turned upward ; 
maxillary about as long as the orbit. Tongue broad, rounded, with a 
broad villiform band of teeth. Teeth in villiform bands on jaws and 
tongue, and in three short broad closely placed patches on the vomer 
and palatines. Eyes medium; orbits converging forward, in length one 
sixth of the width of the disk, twice the length of the snout,.one and 
one half times the width of the interorbital space, covered with finer 
seales than those of the surrounding parts of the head. Gills two, none
