CANARIAN GROUP. 43£ 



Several examples of this large Bulimus which were taken by 

 Mr. Lowe and myself in the calcareous district between Lagaete 

 and Gaidar, on the western side of Grrand Canary, were referred 

 by Mousson (to whom I sent them for inspection) to the B. 

 obesatus, W. et B. ; and, curiously enough, he does not appear 

 to have separated them at all (not even as representing a ' va- 

 riety ') from some normal ones of that species, which I likewise 

 forwarded to him, and which were met with in the region of El 

 Monte and towards Las Palmas. Yet it seems to me that they 

 are so totally different from the true obesatus-tji:>e that I can- 

 not but regard them as specifically distinct ; and I have conse- 

 quently defined them as such, under the above title. 



As regards mere leng-th, the B. interpunctatus does not differ 

 much from the obesatus ; nevertheless from being narrower and 

 more cylindrical, it has the appearance at first sight of being a 

 little longer than that species. It is, however, conspicuously 

 more parallel in outline and less ventricose, — its spire (which is 

 less papilliform at the apex) being more strictly cylindric 'poste- 

 riorly, and its basal volution being less inflated and convex. Its 

 colour too is apparently paler (or less brown), its surface is some- 

 what more decidedly opake, its aperture is perhaps not quite so 

 broad (the upper and lower margins being appreciably less wide 

 apart), and its sculpture is different, — the oblique striae (which 

 perhaps are not quite so coarse) being, particularly on the inter- 

 mediate whorls, separated from each other by rather large but 

 shallow, irregular, and ill-defined punctures.

The three examples from which the above diagnosis has been 

 compiled were taken by Mr. Lowe (on the 22nd of February, 

 1859), on the mountains above Sta. Cruz, in Teneriffe, in the
