Intermediate Trichiurus. Trichurus intermedins, n. s. Head rather 
short, tapering in front, compressed on the sides, rather less than one- 
ninth the length of the body; forehead sloping, arched, sharply keeled ; 
jaws conical, and slightly produced in front ; front teeth very long, barbed, 
hinder ones moderate, rather distant, equidistant, front ones small, and 
close set; chin slender, rounded at the end; intermaxillary bones sharply 
curved in front, reaching as far as under the front edge of the eye ; body 
compressed, lateral line nearly straight, continued along rather below the 
centre of the body; the vent with a short broad spine behind it, and a 
series of very minute spines along the ventral line of the body, and partly 
along the tail; tail rather short, thickish. Length 15:§ inches. 
Armless Trichiurus. Trichiurus Muticus, n. s. Head short, taper- 
ing in front, rather rounded on the sides, rather less than one-tenth the 
length of the body ; the forehead sloping, arched, sharply keeled, jaws 
conical, and slightly produced in front ; front teeth long, incurved, simple ; 
the hinder teeth small, close set; chin slender, slightly produced ; intermax- 
illary bone short, curved, scarcely reaching to under the front edge of 
the eye ; body compressed, lateral line nearly straight, continued along 
just below the centre, five-sevenths of the height of the body; vent with- 
out any spine behind, with a series of very minute spines at the end of 
the body, near the base of the tail. 
Cuvier has indicated three species of Regne Animal, but so shortly 
that I cannot determine if any of these belong to them ; when he was in 
this country he believed these to be new to him ; nor are the descriptions 
of other naturalists more easy to make out. 
Description of some new Species of fresh-water Shells discovered by 
Capt. Owen, R.N., on the Coast of Africa. 
Dr. Maton's Melania. Melania Matoni. n. s. Murex fuscatus, 
Maton, Linn. Trans. VIIL, t. 4, f. 6, not Linn. Shell turreted, trun- 
cated, brown ; upper whorls with four spiral grooves crossed by waves 
grooved, forming small round tubercles ; lower whorl smooth, with two 
high, sharp, spiral keels, the upper the highest ; the front of the last whorl 
spirally grooved ; mouth ovate, narrow, slightly grooved n front ; outer 
lip rather expanded, crenulated. Axis, 1 inch, diam. 4^ lines. 
Four-pearled Melania. Melania quadriseriata. Shell turreted, 
truncated, brown ; whorls nearly flat, each with four spiral ridges, crossed 
by transverse grooves, which form the ridges into roundish tubercles, of 
which those of the hindermost series of the lower whorl are the largest ; 
the front of the last whorl smooth, spirally grooved ; mouth ovate, nar- 
row, slightly grooved in front ; outer lip expanded, rounded, crenulate, 
Is it a variety of M. Matoni, as it is exactly like the apex of that species 
Axis 12, diam. 4 lines. 
Capt. Owen's Melania. Melania Owenii, Gray, Ency. Metrop. t. 
, f. . Strombus Byronensis, Wood. Suppl. t. 4, f. 23. Shell 
turreted, ventricose, subtruncated ; brown varied with black ; whorls 
flatish, with two rows of large conical, truncated tubercles on each whorl.
