CANARIAN GROUP. 435 



Th,e B. bceticatus is a species which is peculiar to Tene- 

 riffe ; and although it has been brought away by most of the 

 naturalists who have visited that island (including Mauge, 

 Webb and Berthelot, d'Orbigny, Blauner, and Grasset), it is 

 nevertheless, so far as my own experience would imply, one 

 of the rarer forms. I possess examples however from the neigh- 

 bourhood of Sta. Cruz, and others which were taken by Mr. 

 Lowe (during April of 1861) in the Barranco de Majuelo near 

 Garachico. 



The large size, and broad, inflated, rounded-ovate outline of 

 the present Bulimus, the spire of which is short and suddenly 

 acuminated (the extreme apex itself being somewhat prominent 

 and papUliform) added to its rich reddish-brown and more or 

 less olivaceous hue, its rather thin substance, its enlarged aper- 

 ture, and its curious sculpture, the surface (which is opake) 

 being much roughened by irregular, undulating or somewhat 

 vermiform, subconfluent folds or ridges (which give it ascabrose, 

 rather than a granulated, appearance), will suffice to distin- 

 guish it.

A Teneriffan Bulimus, occurring more particularly in damp 

 and wooded spots of intermediate and rather lofty altitudes, 

 but ascending also (like the B. nanodes) into the region 

 of the Eetamas, to an elevation of about 9,000 feet. I 

 met with it principally, however, within the forest districts, pro- 

 perly so-called, such as at the Agua Mansa, the Agua Garcia, 

 Las Mercedes, the wooded slopes above Taganana, and in the Final 

 above Ycod el Alto ; and it is stated by Mousson to have been
