722 DR. J. C. cox ON NEW AUSTRALIAN LAND-SHELLS. [Juiie 27, 



9. On some New Species of Australian Land- Shells. By 

 James C. Cox, M.D., F.R.C.S. Edin., Secretary of the 

 Entomological Society of New South Wales. 



Since the issue (in 1864) of a 'Catalogue of Australian Land- 

 Shells' in my collection, in which many supposed new species were 

 described, I have from time to time transmitted, for publication in 

 the ' Proceedings ' of the Society, descriptions of such others as 

 appeared to me to be novelties ; and I now send a further contribu- 

 tion to the same effect. I mention that a work which I am now 

 preparing for the press, in which all the Australian Land-Shells 

 known to me will be described (in Enghsh) and represented by 

 coloured plates, will, I trust, be published before any considerable 

 number of new shells can have come before me, even supported as 1 

 have been and still am by the contributions of collectors in all the 

 Austrahan colonies, Ilowever, by next mail I hope to be able to 

 send descriptions of some more undescribed species. 



1. Helix lamproides, mihi. 



H. testa vmhilicata, convexo-depressa, temii, conferte et irregu- 

 lariter costato-striaf.a, supra vix nitida, infra nitidiore, corneo- 

 rufescente, subtus pallidiore ; spira parvula, convexiuscula, ob- 

 tusa ; anfr. 4, celeriter accrescentibus, ultimo non descendente, 

 supra depresso, infra convexo, obtuse angulato ; apertura obli- 

 qua, rotimdato-lunata ; peristomute simplici, tenui, marginibus 

 conniventibus, dextro recto, antice angulato, columellari arcuato, 

 non dilatato, nee reflexo. 



Diam. maj. 0-57, min. 0-50, alt. 0-22 unc. 



Hab. North-western coast of Tasmania. 



Closely allied to H. lampra, Pfr., but more coarsely sculptured 

 and wanting the extre.ne polish of that species, besides being ob- 

 tusely carinated, and having the aperture angular externally. 



2. Helix hamiltoni, mihi. 



H. testa umbilicata, subdiscoidea, convexo-depressa, tenui, con- 

 ferte subarcuatim costulata, interstitiis tenuissime filosis, lineis 

 minutissimis spiralibus cceteras decussantibus, faciem (sub 

 lente) lineato-yranulatam exhibente, hand nitida, pallide rufes- 

 cente-cornea ; spira jiarva, vix prominente, interdum planata, 

 sutura impressa ; anfr. 5, celeriter accrescentibus, planato- 

 convexiusculis, ultimo subinflato, rotundo-convexo, non antice 

 descendente, ad os supra modice planato, basi sti'iis minoribus 

 munito ; umbilico perspectivo, fere i diametri cequante ; aper- 

 tura diayonali, ovato-hmari ; peristomate simplici, tenui, recto, 

 marginibus conniventibus, columellari supra modice dilatato 

 et reflexo. 

 Diam. maj. 0'j3, min. 0-4.">, alt. 020 unc.
