434 TEST ACE A ATLANTIC A. 



Habited TenerifFam ; in regionibus valde elevatis (praeser- 

 tiiu sylvatiois), usque ad 9,000' s.m. parce ascendens. 



Although larger than the osonensis, this is one of the 

 smallest of the Canarian Bulimi on the robust and more or less 

 barrel-shaped type ; and it is one which seems to be peculiar to 

 the elevated districts of Teneriffe, — where it occurs beneath 

 fallen leaves, stones, and logs of wood. I have taken it in the 

 sylvan region above the Agua Mansa, and in the lofty Pinal above 

 Ycod el Alto, as well (amongst the Retamas) on the Cunibre 

 overlooking the Caiiadas, — at an altitude of at least 9,000 feet ; 

 and it appears to have been found previously both by Blauner 

 and Eeiss. 



Apart from its small size, as compared at any rate with 

 most of the following members of the group, the B. nanodes 

 may be recognized by its obtuse and rather oval outline (the 

 intermediate whorls being a little inflated and very convex), 

 by its surface being more or less coarsely roughened with short 

 groove-like varioles, separated by undulating ridges or reticula- 

 tions which have the appearance sometimes of merging into 

 granules, by its colour being of a pale but dirty yellowish- 

 brown, and by its aperture being not much enlarged, but with 

 the peristome (the margins of which are joined by a thin and 

 simple intervening lamina) broadly expanded.
