 Bulimus obesatus, Pfeiff., Mon. Hel. viii. 70 (1876) 



Habitat Canariam Grandem ; in intermediis, ad El Monte, 

 et cset., sat vulgaris. Etiam in statu semifossili reperitur. 



This is the common Bulimus, on the large and barrel- 

 shaped type, in the intermediate and but slightly elevated dis- 

 tricts of Grand Canary, where it is universal throughout the 

 region of El Monte and on the calcareous hills above Las Palmas, 

 localities in which it was likewise met with by Webb and Ber- 

 thelot, as well as by Fritsch. Many examples of it are also now 

 before me which were taken by Mr. Watson, a certain number of 

 which are in a subfossilized condition. 



In its elongate-ovate outline and somewhat lengthened colu- 

 mella, the B. obesatus is on much the same pattern as the B. 

 Tarnerianus of Teneriffe ; nevertheless it is a little larger, 

 broader, and more ventricose, with its volutions natter, and with 

 the extreme apex of its spire rather more prominently papilli- 

 form. The striae, also, of its surface, although, coarse and 

 irregular, are nearly simple, being hardly, if indeed at all, 

 broken-up into what might be defined as elongated granules.
