DISCUSSION OF SPECIES AND THEIR DISTRIBUTION. 



185 



Lower jaw quite deep with an upi)er and lower portion longitudinally striated ami an 

 intermediate region provided with a naked skin, and with its angle emitting a s])ine back- 

 ward; chin fiatteued backwards to a median inferior point; teeth enlarged and few, in a 

 single row in each Jaw. (1) In the upper a pair slightly curved and regularly jjointed. dos- 

 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 fove;e of the palate on each side; two smaller teeth 

 nearly straight and with globular i>oints, the first intermediate between the first and 

 second of the upper, and the second behind the second lateral tooth of the upper Jaw; 

 palate and tongue edentulous. (3) A row of very small teeth around the ])osterior half of 

 the supramaxillary. 



Dorsal single, commencing above the upper axil of the pectoral, with 2 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 S bifurcate rays, the last double; caudal deeplj' emargin- 

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

 and about 1-t branched rays; ventral fins subabdominal or decidedly behind the i)cc- 

 torals, withl spine and branched rays. Branchial apertures dcei)ly deft; 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 and pedunculate. Color, uniform 

 black.
