This species recalls the small form (var. semicastanea) oi 

 11. hipartiia, but is distinguished by the obtuse keel, wider 

 umbilicus, less elevated spire, colour, &c. 



5. Helix [Dorcasia) suhpUcifera. 



Testa depresse glohosa, niediocriter umbilicata, solidiuscula, pallide 

 fuccesct'iis, subtus pallidior, liueis increinenti oblique curvatis, in 

 anfr, ultimo subpliciformibus, sculpta ; spira brevis, conoidea, ad 

 apicem obtusa ; anfractus 5, convexi, sublente accrescentes, sutura 

 profunda sejuncti, primus minute punctatus, ultimua antice 

 descendens ; apertura obliqua, late lunata, dilutissime rufescens ; 

 peristoma albidum, anguste expansum et reflexum, margine 

 columellari superne ddatato, umbilicum partim obtegente. 



Diam. maj. 20| miUim., min. 17, alt. 14; apertura intus 8| alta, 

 9 lata. 



This species bears some resemblance to H. argillacea^ 

 Ferus., when viewed from above. It is, however, less 

 globo.'^e, more depressed, more widely umbi Heated, has a 

 smaller aperture, and is more plicately sculptured. Only the 

 apical wliorl is punctate. 



6. Helix [Chloritis) ephaviilla * . 



Testa H. Leer simillima, sed plerumque paulo major, spira leviter 

 altiore, apertura latiore, livida, labro latius expanso, umbilico vii 

 granulate. 



Diam. maj. 34 millim., min. 27, alt. 23; apertura intus 13 alta, 

 14 lata. 



This form may be the var. papuensts of H. Leei, which is 

 referred to by Mr. Hedley (Proc. Linn. Soc. N. S. \V. 1891, 

 vol. vi. p. 83), and it is with considerable hesitation that I 

 venture to distinguish it specifically from that species. Be- 

 sides the differences above mentioned, it may also be remarked 

 that the colour of the peristome is reddish in H. Leei and 

 livid in the present species, becoming much darker in some 

 specimens at the umbilicus. All the examples are clothed 

 with an olivaceous epidermis, beset with very short stiff 

 bristles. These are generally more or less worn off, but their 

 position is indicated by n^inute pitting all over the surface. 

 A curious difference in the relative weight of the different 

 parts of the shell is shown by the position it assumes when 

 placed on a flat surface with the aperture downwards. In 

 II. Leei the peristome rests upon the surface, the spire being 

 lateral, wliercas in //. ephamilla the apex is vertical and the 

 lip stands erect.
