It is possible that this Pupa may represent but a rather 

 large and aberrant, or even depauperated, state of the P. 

 sphinctostoma, in which the plaits are reduced and the outline 

 of the mouth is modified ; nevertheless I do not think that it 

 would be at all safe to treat it as such. It seems to differ from 

 the P. sphinctostoma, not only in being on the average some- 

 what larger or more elongate, as well as a little more tapering 

 towards its apex and more appreciably striated (at any rate 

 more so than the normal phasis of that species, though not so 

 much so as the ' var. a. rupestris ' which I cannot but think 

 may prove eventually to be distinct), but likewise in its aper- 

 ture being much more rounded (or less produced-outwards) at 

 the angle of the lip, and with the tooth which bounds the 

 ' sinus,' as well as all the plaits, much less developed. Indeed 

 so far as the latter are concerned, the outer ventral one (which 

 is unconnected with the angle by a corneous sphincter, or rim) 

 is alone elongate and conspicuous, and even it is shorter, 

 thinner, and more oblique than is generally the case in the 

 various states of the P. sphinctostoma, the upper columellary 

 and the upper and lower palatial ones being apparently obsolete ; 

 whilst even the interior ventral, the lower columellary and the 

 central palatial ones are small, inconspicuous, and deeply 

 immersed. 



The only locality, so far as I am aware, in which the P. 

 Icevigata has hitherto been observed is towards the head of the 

 Ribeira de Santa Luzia, in the south of Madeira proper, 

 where I have often met with it sparingly, in company with the 

 large and pallid variety of the Clausilia crispa, beneath the 

 dead and loosened bark of old laurel-trunks.
