ACTINOPTKRYGII. 
272 
Teeth apparently wanting on the margin of the jaws ; but stout 
and blunt conical teeth present on some of the inner bones of the 
mouth, probably on the pterygoids and hyoid apparatus; upper 
branchiostegal rays comparatively broad. Vertebrae approximately 
>70 in number, 35 being abdominal and the remainder caudal , ri ' 
short and delicate. Paired fins relatively largo, the pectorals no 
much exceeding the pelvic pair in size, the latter remote an< 
opposed to the origin or anterior part of the dorsal, which is scarce } 
if at all behind the middle of the back ; dorsal and anal fins eac i 
with from 7 to 12 rays ; caudal fin slightly forked. Scales distinct J 
elongated [but their hinder margin not yet observed]; n0 
extending over the head ; strong fulcral scales on the borders o 
caudal pedicle at the base of tho caudal fin.

The type species, known only by one imperfect specimen

trunk nearly similar in proportions to that of the latter, bu 
caudal pedicle apparently more robust.

Charitosomus major, sp. nov. 
[Plate XV. fig. 3.] 
Type. Imperfect fish ; British Museum. . 
A species attaining a length of about 0-2. Length of 
opercular apparatus contained four and a half times, and ^ () 
depth of trunk nearly nine times in the total length of t e 
the base of the caudal fin ; depth of caudal pedicle about 1(1 ^ - n 
of the abdominal region. Dorsal fin almost median, arisin B 1 
advance of the middle point between the occiput anu < ^ near ly 
the caudal fin; pectoral fin-rays when adpressed exten K'o 
half way to the pelvic fins, which arise opposite the 811 a ^ oll t 
of the dorsal ; distance between tho pectoral and pelvic 
one and a half times as great as the length of the 88 caU j a i 
opercular apparatus ; anal fin arising slightly nearer to 
than to the pelvic fins.
