Habitat Canariam Grandem; in intermediis, ad El Monte, 

 et cast., 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 flatter, and with 

 the extreme apex of its spire rather more prominently papilli- 

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

 irregvZar, are nearly simple, — being hardly, if indeed at all, 

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