Body smooth, and without scales. Eyes placed one on each side of the head. Branhcial 
rays six, 
GENUS LUMPUS. Cuvier. 
Two dorsals ; the first often so much enveloped in a tuberculous skin, as to appear like a 
hump of the back. Second ‘dorsal with rays, and opposite to the anal. Body deep and

Characteristics. Blue. Three series of tubercles along the sides. Dorsal lump with a fissure 
on its posterior part. Length ten to twenty inches. 
Description. Body suborbicular in its outline, compressed, more especially towards the 
dorsal ridge. It is soft and flaccid, resembling a lump of jelly. Instead of scales, the body 
is covered with minute tubercles, and horizontal series of larger ones. From the anterior 
portion of the dorsal ridge, the outline slopes in a concave line to the orbits, where it becomes 
abruptly declivous to the snout. The space between the orbital ridges, flat. On the top or 
ridge of the back, is a series of from five to seven large compressed tubercles, and a smaller 
row on the anterior slope. Behind the large tubercle, there is a deep oblique fissure ; poste- 
rior to which the dorsal surface becomes flat, with a series of from three to five sharp unequal 
tubercles on each side, the posterior largest. A series of large tubercles commences before 
the eyes, curves over the pectorals, and then proceeds ina straight line through the upper part 
of the tail. Another series of which the first four are very large and closely approximated, 
commences a short distance above the ventral part of the branchial aperture, curves slightly 
downward, and, with a slight interruption, passes through the lower part of the tail; there is 
still another series on each side of the abdomen, consisting of about six inequidistant large 
tubercles. Eyes lateral, prominent. Nostrils double ; the anterior large and tubular ; the 
posterior scarcely perceptible, when they will be found just within the first large tubercle, on 
the superciliary ridge. Branchial rays four, slender. Mouth moderately large, broad; the
