70. Helix Georgiana. Quoy et G aim ard. Plate XIX. Fig. 1. 

 Quoy et Gaimard, Voy. do V Astrol. et ZeUe. Moll., p. 129. PI. X. 



P. 2630 

 Desh., in Per. Hist. Moll 1, p. 88. N. 119. PL LXXXIV. P. 34. 



Shell sub-discoid, depressed, thin, brittle, translucent, yellow, above 

 very finely and deeply striated, beneath smooth and widely umbili- 

 cated ; spire very short ; whorls 4, slightly convex, last large ; 

 aperture oblique, simple, sub -circular. 



Diameter 0-43 ; height - 24 of an inch. 



Habitat. King George's Sound. Quoy et Gaimard. 



The above is a translation of Deshaye's description, in preference to 

 the original one of its first describers. The figures indicate a shell 

 of the size of U. splendulula, but with exceedingly delicate, regular 

 ribbed lines throughout, even descending into the umbilicus. 



71. Helix Walkeri. Gray. 



Zonites "Walkeri. Gray, Pro. Zool. Soc, 1834, p. 63. 



Shell depressed, umbilicated, polished, yellowish-brown ; whorls 3-|, 

 very quickly increasing, ventricose, finely concentrically striated 

 above with dense spiral stride umbilicus deep ; aperture large. 



Axis 8 lines ; diameter 1 inch. 



Habitat. About seventy miles from Port Macquarie. Cunningham. 



This must be closely allied to II. capiUacea, and H. strangei. The 

 original description is given verbatim, as I have not seen an 

 authentic specimen, nor has Pfeirfer. It appears to me that the 

 word concentrically" is a mistake for " radiately ;" the fact of 

 "spiral" or concentric stria) having been subsequently mentioned 

 indicates this. 



72. Helix lampra. Pfr. Plate X. Fig. 9. M.C. 

 Pfr., Pro. Zool. Soc., 1854, p. 53. 



Peeve, Cone. Icon. sp. 1295. 



Shell umbilicated, convexly-depressed, chin, horny, translucent, very 

 glossy, with fine arcuate rib-like stria?, from dark green to deep 

 greenish-chestnut ; spire small, convex, obtuse ; whorls 4, quickly 

 increasing, last depressed, expanded outwardly, not descending in 

 front ; base smoother, bright greenish-yellow ; umbilicus about l-5th 

 of the diameter ; aperture lunately-oval, nearly diagonal ; peristome 

 simple, thin, straight, margins converging, columellar margin very 

 slightly reflexed above. 



Diameter, greatest 0-90 ; least 0*70 ; height 0-30 of an inch. 



Habitat. Launceston, Tasmania. Gunn. 



A remarkably glossy species, occasionally of a uniform olive green. 



73. Helix lamproides. Cox. Plate X. Fig. 13. M.O. 



Cox, Pro. Zool. Soc., 1867. 



Shell umbilicated, convexly-depressed, thin, closely and irregularly

 reddish, paler beneath ; spire small, slightly convex, obtuse ; whorls
