Habitat Palmam ; in declivibus intermediis, ad rupes et 

 inter saxa latens. 



This beautifully variegated Bulimus seems to be peculiar to 

 the intermediate and rather lofty districts of Palma, — where it 

 was found by Mr. Lowe and myself in several places, though 

 more particularly in the Barranco de Nogales, chiefly amongst 

 rubbish and small stones on the ledges of the rocks ; and it ap- 

 pears to have been taken also by Blauner. Mousson, by some 

 unaccountable mistake, has cited my examples from the Bar- 

 ranco de Nogales as referable to the B. variatus ; whereas they 

 possess every character of Shuttleworth's B. encaustus ; though 

 it may be a question perhaps whether tlie latter, though easily 

 distinguishable, is anything more in reality than an insular and 

 highly decorated modification of the B. variatus. Still I have 

 already stated what my reasons are for preferring to retain these 

 nearly-resembling Bulimi in the condition in which they have 

 already been acknowledged and published. 



It is to the typical form of the B. variatus (which is more 

 or less obscurely ornamented with longitudinal paler dashes and 

 streaks) that the B. encaustus the most intimately approaches ; 

 nevertheless it is, on the average, rather larger and more solid 

 than the former, more shining and uneven in its surface (irregu- 

 lar longitudinal spaces of which, between certain striae which 

 are more elevated than the rest, have a tendency to be very 

 obsoletely scooped-out, as it were, or grooved) ; and the frag- 

 mentary oblique patches and lines are not only very much 

 increased in size, — frequently becoming confluent with each 

 other, so as to cover nearly the whole shell. Its aperture, too, 

 is relatively a trifle more developed, the columellary margin 

 being (if anything) a little longer ; and its whorls are altogether 

 somewhat less abbreviated, causing the general outline to be 

 more in accordance with that of the B. myosotis.
