630 ON THE PECULIARITIES OF MADEIRAN ACHATINE. [ Dee. 7. 
Lovea (AcHATINA) TORNATELLINA, Lowe. 
Colour darkish grey, somewhat speckled, extending along above 
the foot to the tail-gland; the foot is gelatinous, translucent, lighter 
grey. 
Mantle whitish with a very slight tinge of grey ; it spreads well 
out beyond the lips of the aperture and is in perpetual movement 
upon the shell ; it is simple, but extends backwards in a tongue half- 
way across the second last whorl. 
Tentacles long, rather fine, the under ones rather short ; they and 
the body finely tubercled. 
Foot narrow. Tail extending quite to the apex of the shell, very 
slender, with a gland above just short of the end of the tail. 
Jaws and radula exactly resemble those of 4. melampoides, except 
that they are smaller. 
Lovea (AcHatina) TRITICEA, Lowe. 
Colour. General effect blackish ; of the foot translucent white, 
with a faint tinge of olive-green. Body slightly smoky brownish, a 
streak of which runs out (above the light edge of the foot) on either 
side towards the caudal gland, but dies out just before reaching it. 
Mantle coloured like the body, but rather lighter, stretching out 
round the aperture so as to embrace the shell. 
Tentacles short, small, very black, with minute black dots of eyes 
on the upper point; under tentacles very short, lighter than the 
the upper ; eyes distinct (?). Body and tentacles very finely tuber- 
cled. : 
Foot narrow. Tail long, narrow, ending below in a sharp point, 
with an abrupt truncation rising obliquely to a sharp angulation 
above for the caudal gland, which rises just short of the end of the 
tail. ‘ 
Jaw and radula exactly like those of Lovea melampoides, only 
smaller. 
Lovea (AcHatina) oryza, Lowe. 
In every thing but colour this species exactly resembles the pre- 
ceding. 
eS General effect is a slight ruddy brownish, having no part 
dark but the muscles of the tentacles, of which the upper are dark 
black grey and the under are light. 
Mantle is just like the body in colour. The projecting flap covering 
the caudal gland is very well marked. 
The upper surface of neck and head and also the tentacles are finely 
tubercled, while the sides of the head and neck are marked by long 
fine lines as if the tubercles were there confluent in this form. The 
eyes are very black and well marked. 
The animal, like the others which I have observed, crawls slowly 
and brings up its shell after it by periodic jerks.
