Buliminus nanodes, var. palmaensis, Mouss., Faun. Mai. 

 des Can. 116 (1872) 



Bulimus nanodes (pars), Pfeiff., Mon. Hel. viii. 73 (1876) 



Habitat Palmam ; in sylvaticis editioribus, late sed parce 

 diffusus. 



It is surprising to me that this Bulimus, which is one of 

 the best defined of all the Canarian species, should have been 

 cited by Mousson (from examples which I sent to him for 

 inspection) as a mere ' var. palmensis ' of Shuttle worth's B. 

 nanodes, which is utterly distinct from it in every one of its 

 characters. Apart from its greater length (which is fully 

 6 lines, instead of scarcely 5), and its more fusiform, medially 

 widened, apically acute outline (the spire being more regularly 

 conical, with the whorls much flatter), it is additionally 

 separated from every phasis of the B. nanodes by its thinner 

 and more pellucid substance, its very much larger and more 

 oblique aperture, its longer and less vertical columella, its less 

 expanded peristome, its paler and more olivaceous surface 

 (which is occasionally almost lutescent, and not unfrequently 

 obscurely marked with lighter dashes and spots, thus taking 

 us back again, as it were, towards the variatus group), and its 

 totally different sculpture, the shell being altogether free 

 (except towards the umbilical region) from the coarse varioles 

 and irregular granulations which are so conspicuous in that 

 species, but at the same time more or less covered with exces- 

 sively minute (and often barely traceable) densely-packed spiral 

 lines. 



The present Bulimus seems to be universally (though 

 sparingly) distributed over the intermediate and lofty sylvan 

 districts of Palma, to which island it would appear to be 

 peculiar. It was met with by Mr. Lowe and myself on the 

 ascent of the Cumbre above Buena vista, as well as in the 

 Barranco above Sta. Cruz, the Barrauco de Agua, and the Bar- 

 ranco de Gralga, and by Mr. Lowe at El Monte above Barlovento. 



Bulimus badiosus.
