722 ITR. J. C. cox ON NEW AUSTRALIAN LAND-SHELLS. [June 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 English) 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 

 Australian colonies. However, by next mail I hope to be able to 

 send descriptions of some more undescribed species. 



1. Helix lamproides, mihi. 



IL testa vmhilicata, convexo-depressa, tenui, conferte et irregu- 

 lariter costato-striata, supra vix nitida, infra nitidiore, corneo- 

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

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

 supra depresso, infra convexo, obtuse anyulato ,- aperturu obli- 

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

 conniventibus, dextro recto, aiitice anyulato, coJumellari arcuato, 

 non dilatato, nee rejiexo. 



Diam. maj. 0'57, min. O'oO, alt. 0*22 unc. 



Hab. North-western coast of Tasmania. 



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

 and wanting the extreaie polish of that species, besides being ob- 

 tusely carinated, and having the aperture angular externally. 



2. Helix hamiltoni, mihi. 



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

 ferte subarcuatim costulata, interstitiis tenuissime Jilosis, lineis 

 minutissimis spiralibus cceteras decussantibus, faciem (sub 

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

 cente-co7-nea ; spira parva, 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 striis minoribus 

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

 tura diagonali, ovato-lunari ; peristomate simplici, tenui, recto, 

 marginibus conniventibus, columellari supra modice dilatato 

 et refexo. 



Diam. maj. 0'^3, min. 0'4.0, alt. 020 unc.
