This species recalls tlie small form (var. semtcastanea) of 

 H. h'vartita, but is distinguished by the obtuse keel, wider 

 umbilicus, less elevated spire, colour, &c. 



5. Helix [Dorcasia) suhpUcifera. 



Testa flcproRse globosa, mediocriter nmbilicata, solidiuscula, pallide 

 fuscesffiis, subtiis pallidior, lineis incrementi oblique curvatis, in 

 anfr. idtimo subpliciformibus, sculpta ; spira brcvis, conoidea, ad 

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

 profunda sejuncti, primus minute punctatus, ultimus antice 

 descendeus ; apertura obliqua, late lunata, dilutissime rufescons ; 

 peristoma albidum, aiiguste expansum et reflexum, margine 

 columellari superne ddatato, umbilicum partim obtegente. 



Diam. maj. 20^ millim., miu. 17, alt. 14 ; apertura intus 8:^ alta, 

 9 lata. 



This species bears some resemblance to H. argxUncea^ 

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

 globose, more depressed, more widely umbilicated, has a 

 smaller aperture, and is more plicately sculptured. Only the 

 apical wliovl is puijctate. 



6. Helix {Chloritis) ephamilla^. 



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

 altiore, apertura latiore, livida, labro latius expanse, umbilico vix 

 granulate. 



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

 14 lata. 



This form may be the var. jyaimensis of //. Leei, whicli is 

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

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

 venture to distinguish it specitically from that species. Be- 

 sides the differences above mentioned, it may also be remarked 

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

 livid in the present species, becoming much darker in some 

 specimens at the umbilicus. All the examples are clotiied 

 with an olivaceous epidermis, beset with very short stiff 

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

 position is indicated by minute pitting all over the surface. 

 A curious difference in the rehative weight of the different 

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

 placed on a flat surface with the aijerture downwards. In 

 JrL Leei the peristome rests upon the surface, the spire being 

 lateral, whereas in LL ephamilla the apex is vertical and the 

 lip stands erect.
