Habitat Teneriffam juxta Sta. Cruz, prsecipue in ' Bar- 

 ranco del Passo Alto,' vulgaris. 



This is one of the most abundant of the larger Bulimi 

 around Sta. Cruz in Teneriffe, to which island it would seem to 

 be peculiar. It was taken in profusion by Mr. Lowe and 

 myself near the mouth of the Barranco del Passo Alto, and it 

 has been met with by almost every naturalist who has 

 visited the Canaries, including Mauge, Webb and Berthelot, 

 d'Orbigny, Blauner, Fritsch, Eeiss, and Watson. 



Apart from its ovate (or basally-widened and apically-acute) 

 outline and its reddish-brown, somewhat chestnut hue, the 

 B. badiosus may be known by its rather enlarged, oblique, and 

 regularly curved (unangulated) aperture, the whitened peristome 

 of which is broadly thickened internally, and by the incrassated 

 corneous rim (sometimes evanescent in the centre) which joins 

 the margins of the latter, and which is developed near to the 

 right-hand insertion into a nodule which is separated by a 

 minute gash (or incision) from the angle itself. This last- 

 mentioned character is possessed also by the B. helvolus, 

 Bertheloti, and Consecoanus, but it is one which does not 

 appear to be noticed in the published descriptions of the 

 species. Judging from the many examples which are now 

 before me, the B. badiosus very seldom has its surface at all 

 granulated except at the extreme base of the shell ; but the 

 irregular (or unequal) striaB are somewhat coarsely expressed.
