second dorsal and the anal have a very large number of rays 
(over twenty) ; the head is entirely scaly ; the first dorsal is 
comparatively smaller, and the dentition is dilFerent. 
The lower jaw is obtuse, and considerably longer than the 
other ; on the upper one the teeth are small, almost equal, but 
the centre ones rather larger than the others, and are numerous. 
Behind this is a band of very numerous, villiform, and very small 
teeth ; this band is narrow in front and behind, but broad towards 
the centre of the jaw. In front, there are on each side two very 
large fangs, the posterior one much longer than the other ; on 
each palatine there is a single line of very small teeth, and some 
larger ones on the vomer. At the lower jaw, there is a line of 
very minute teeth, which does not extend in front, but is replaced 
in this part by rather large, acute ones, directed backwards ; 
towards the middle, and inserted behind the line I have men- 
tioned, there are on each side two large fangs, apart one from 
the other. In some specimens there are three. The head is 
entirely scaly, and its upper part has no longitudinal sulcates ; 
the prseoperculum is rounded, and finely ciliated on its margin ; 
the operculum terminates with a rather prolongated, obtuse, flat 
point. Scales rather large ; they fall easily ; the lateral line is 
well marked, continuous ; the ventrals are united at their base ; 
they are formed of one spine and five rays. 
NEOSPHTEiEFA MULTIEADIATA. 
Body thick and rather short ; contained about six and a-half 
times in the total length ; the head three and two-third times in 
same ; the orbit four and two-third times in the length of the 
head. The snout is rather short; the distance between the 
extremity of the upper jaw to the anterior orbit being equal to 
the distance between the posterior edge of the same orbit and 
the extremity of the operculum ; head entirely scaly ; the lower 
jaw longer than the upper one by one-half the diameter of the 
eye ; the lateral line running over about seventy-five scales, which 
fall very easily ; the first dorsal is formed of five rays ; the second 
dorsal of from seventeen to twenty-one rays ; its anterior part 
much higher than its posterior one ; the caudal is emarginated, 
with sixteen rays ; the anal is longer than the dorsal, with twenty- 
eight rays ; the ventrals, placed almost below the pectorals, are
