4A, Mr. R. T. Lowe on a new Madeiran Helix. 
licus, and some other peculiarities of sculpture, H. delphinuloides 
is allied to H. Delphinula, it is a truly distinct species; and the 
fact that one so large and remarkable has remained so long un- 
discovered in Madeira only gives, as before observed, fresh vigour 
to the hope that the real H. Delphinula, in a living state, will 
even yet reward the diligent researches of some explorer of the 
more retired glens and interior recesses of that apparently in- 
exhaustible and wondrous field, the inner ravine and mountain 
region of Madeira. The locality of the present nearly connected 
species suggests the probability that, like so many others of the 
Canical fossil shells, H. Delphinula also was a sylvan species, 
and that it is consequently to be looked for in the higher forest 
regions of the island.

Animal a true Helix: yellowish brown; sides of foot pale 
cinereous ; the whole with a warm pale sienna tint. Tentacles, 
and a line backwards from the base of each, blackish ; the upper 
pair rather long. 
Averse to move, but not slow or timid when once in motion. 
When quiescent, the pointed yellowish-brown tip of the foot 
appears within the mouth of the shell; but when disturbed, the 
animal retracts itself far back within. When brought down to 
Funchal, the animals all died in three or four days.
