334 REV. R. B. WATSON ON MADEIRAN MOLLUSKS. [Apr. 17, 
characteristics of the genus;” and I went on to ask “Does the 
Achatina folliculus, Gron., a common European species, belong to 
this new genus or not? Surely, had it possessed the generic pecu- 
liarities mentioned above, the fact would long ago have been noticed. 
I have not yet been able to decide the question as regards the Ma- 
deiran species identified by Lowe as the Achatina folliculus, Gron.” 
I have at last, through the kindness of Mr. T. Vernon Wollaston 
and Mr. Joao Maria Moniz, been enabled to examine the living 
animal of the Madeiran species, and have, as I expected, found it to 
possess the generic features of Lovea as given above. It thus be- 
comes increasingly desirable that some one who has the opportunity 
would make careful examination of the Achatina folliculus, Gron., 
in order to ascertain whether it presents these same generic features 
ornot. Inthe mean time the identification of the Madeiran and the 
South-European species, based on the undeniable similarity of the 
shells, must be regarded as doubtful ; and I propose for the Madeiran 
species the name of Lovea wollastoni, of which I have now to pre- 
sent the description. 
Body. Iu general form very much like that of Lovea tornatellina, 
Lowe. 
Colour. Yellow, towards the tail slightly orange, towards the 
head with a faint tinge of grey, which is darker towards the end of 
the tentacles. The sole of the foot is lemon-coloured, which is a 
little more translucent in front. A very slightly greyer line runs 
above the edge of the foot in front. 
Mantle yellow, but a little whiter and less translucent, having 
a few whitish granules scattered in it. It spreads round and beyond 
the shell-edge ; but my specimens had been long in captivity, were 
dry and unhappy, and thus the mantle was probably less extended 
than would normally be the case. 
Tentacles. Upper long, very fine; lower short. 
Sides scored with long tubercles, of which those above are long 
and narrow, stretching from above forwards and downwards; the 
others below and behind these first are squarer in shape, and 
stretch from before obliquely backwards. The head, neck, and ten- 
tacles are finely tubercled. The foot is bordered by a narrow line, 
above which is a fringe of squarish-shaped tubercles. Two close- 
set and well-marked lines of tubercles run backward from between 
the tentacles along the neck. 
Seen from above, the fai/ ends in an attenuated blunt rounded 
point; seen in profile, it is abruptly cut off obliquely, the extreme 
upper corner being occupied by the mucous gland, the opening of 
which is covered by a flap which, when depressed, almost obscures 
that feature, but which, when the animal is in full vigour, is elevated 
into a short, sharp, triangular, projecting point. 
Mr. Wollaston, in sending me these specimens, writes that Mr. 
Moniz ‘‘says that he obtained them with great difficulty, and, as 
usual, in S. Goncalo parish.” 
In that locality alone have I ever found them, among the dead 
leaves of the Opuntia tuna.
