I believe that I am right in identifying with the 'propin- 

 quus of Shuttleworth two examples of a rather solid, opake, 

 and dark reddish-brown Bulimus which are now before 

 me, and which were taken in the Barranco Santo near Sta. 

 Cruz, — their elongate, cylindrico -ovate outline, extremely 

 convex whorls, deeply impressed suture, and granulate (or, 

 rather, rugoso-, or even scrobiculato-granulate) surface being 

 quite in accordance with the published diagnosis of that species, 

 — which, moreover, is expressly stated by Shuttleworth to have 

 been found ' sub foliis plantarum prope Santa Cruz.' The only 

 point in which it does not completely tally with the description 

 is, that the basal volution can scarcely be said to be in any 

 sense ' angulate ; ' but the faint tendency to an obsolete keel 

 which is sometimes traceable in many of these Bulimi along 

 the dorsal line of their ultimate whorl is so often apt to be 

 undistinguishable that I cannot place much stress upon either 

 its presence or its absence. In addition to the elongate and 

 irregular granulations of the surface, the B. propinquus is 

 also roughly (though unevenly) striate; and its aperture is 

 somewhat rounded and oblique, with the peristome (although 

 acute) a good deal developed. 



I do not feel altogether satisfied that Mousson's B. pro- 

 pinquus is absolutely identical with Shuttleworth's, — it being 

 apparently a larger shell, and defined by him as ' nitidiuscula ; ' 

 but, whether this be the case or not, his species appears to have 

 been taken in Teneriffe by Blauner, Fritsch, and Grrasset, — by 

 the latter at Tagueste. Most likely, however, it represents but 

 a phasis (perhaps more highly developed) of Shuttleworth's 

 type.
