Miguel, and Fayal, — amongst dead leaves in wooded spots of a 

 rather high altitude. In the Canarian archipelago I have taken 

 this very minute shell abundantly, in similar situations, both 

 in Teneriffe and Palma, but always in the dam/pest places. 

 Indeed it was usually to be met with about the fronds and routs 

 of ferns which were kept in a constant state of douche by the 

 spray of the waterfalls ; and I think therefore that Mousson must 

 have fallen into some strange error, in Ms ' Faune Malacolo- 

 gique des Canaries," when he states, apparently on the authority 

 of Blauuer, that it lives ' sous les pierres dans les lieux arides.' 

 Indeed this modus vivendi is absolutely disproved by his own 

 assertion that it exists in company with the Hyalina Clym&ne, 

 Shuttl., and the Pupa castanea; for the only spot in which 

 those two species have ever been observed together (indeed the 

 only one in which the former of them has hitherto been found 

 at all) are some trickling rocks, adjoining a small waterfall, be- 

 tween the little town of Garachico and Ycod de los Yinhos, in 

 the north of Teneriffe, — where they are associated likewise with 

 the A ncylua striatus, Q. et Gr., and the Pltysa acuta, Drap. I 

 suspect, therefore, that the sylvan localities at the Azores in 

 which the H. gutta is to be met with are, as at the Canaries, at 

 any rate damp ones.
