470 PELORID. 
for this species, I now believe that both it and the preceding 
are identical. In the great numbers I have examined during 
the last forty years, 1 have never seen one with such de- 
cidedly long, filiform, sharp-pointed tentacula as to distin- 
guish it as a species; I think therefore we may safely con- 
clude that Montagu’s animal is the L. perspicua. 
VELUTINA, Gray. 
Velutina has a single British species: it has been thought 
to have a close connection with Sigaretus, on which point see 
the remarks under the genus Natica: in addition it may be 
stated, that Velutina has eyes, but no operculum: Sigaretus 
is the reverse ; and whatever it may prove when more investi- 
gated, we shall for the present consider Velutina a good 
genus of the muricidal type; I therefore consign it to the 
Peloride.

Helix levigata, Mont. 
Animal suborbicular, inhabiting a brown auriform shell, 
with a coarsely striated thick epidermis. The mantle is ex- 
tremely large and fleshy, with two emarginations, one bran- 
chial, on the left side of the centre of the shell, the other an 
anal conduit; it is marked in all directions with fine, imtense 
flake-white anastomosing lines; the inflations and thick lo- 
bules of the margim can scarcely be maintained within the 
periphery of the aperture. The head is of Muricidal stamp, 
being a small, flat, almost united membrane, under which is 
the mouth, a mere subvertical fissure, from which the animal 
can exsert a long, cylindrical proboscis, annulated with fine 
flake-white limes; within the orifice is a small white palate, 
supported by two oval, yellowish-brown, striated corneous 
plates, between which is a very short, white, spiny tongue, 
which is quite anterior, not ;4ths of an inch long. The 
tentacula are short, white, not very pointed, and spring from 
the head-veil, with the eyes on slightly raised eminences
