1 Sf, 



Lower jaw quite deep with an uppei and lower portion longitudinally striated and an 

 intermediate region provided with a naked skin, and with its angle emitting a spine back- 

 ward; chin flattened backwards to a median interior point; teeth enlarged and few, in a 

 single low in each jaw. (1) In the upper a pair slightly curved and regularly pointed, clos- 

 ing in front of lower jaw, and on each side two at intervals, behind much smaller and with 

 swollen blunt tips. (2) In the lower jaw a pair near the symphysis more separated than 

 those of the upper and fitting into fovea' of the palate on each side: two smaller teeth 

 nearly straight and with globular points, the first intermediate between the first and 



see I of the upper, and the secoud behind the second lateral tooth of the upper jaw; 



palate and tongue edentulous. (3) .V row of very small teeth around the posterior half of 

 the supramaxillai v. 



Dorsal single, commencing above the upper axil of the pectoral, with LI spines and 17 

 bifurcate rays, the last of which is double; anal short, mostly behind the dorsal, with 2 

 spines, the first very short, and 8 bifurcate rays, the last double; caudal deeply emai fili- 

 ated, but with rounded lobes; pectorals obliquely inserted, of moderate size, with 1 simple 

 and about 14 branched rays; ventral fins subabdominal or decidedly behind the pec- 

 torals, withl spine and 6 branched rays. Branchial apertures deeply cleft; branchiostegal 

 rays, 8.

Greatest height of body one-half its length inclusive of caudal; length of head two and 

 four fifths times in length of body, and almost equal to the height of the body. Upper 

 jaw from the symphysis to the end of the supramaxillary contained 3i times in the total 

 length. The orbit contained 4 times in the length of the head. The front teeth of the 

 upper jaw are considerably longer than the diameter of the orbit; those of the lower nearly 

 twice as long. The scales are very peculiar, foliaceous anil pedunculate. Color, uniform 

 black.
