84 AUSTRALIAN LAND SHELLS. 



aperture diagonal, Innately ovate ; peristome simple, sharp, right 

 margin curved forwards, then gradually rounding to the columellar 

 margin, which is membranous. 



Diameter, greatest 055 ; least - 45 ; height - 17 ; aperture, length - 40 ; 

 brcii (1th 0'35 of an inch. 



Habitat. Australia. T'erreaux. Mount Wellington. North "West 

 Coast, and elsewhere in Tasmania. 



Reeve sa>s this is chiefly distinguished by its narrowly produced trans- 

 verse form ; but this, it must be recollected, is to a much less degree 

 than the words would imply. My Tasmanian specimens, including 

 3 from Cuming, marked V. Verreauxi, B. Tasmania, agree with 

 Pfeiffer's description ; but in it there is no mention made of the 

 membranous columellar margin. 



202. Vitrina castanea. Pfr. Plate XIV. Fig. 11, copied 

 from Reeve. 



Pfr., Pro. Zool. Soc, 1851, p. 56. 



Reeve, Cone. Icon. sp. 37.

polished, chestnut coloured ; spire flat ; whorls 3, scarcely convex, 



the last large, with a broad membranous edge beneath ; aperture a 



little oblicpie, lunate oval ; peristome with a yellow stripe behind its 



membranous margin.

 To the preceding description taken from Pfeiffer may be added, that 



Peeve alludes to it as a bright transparent shell, of a rich chestnut 



olive hue. 



203. Vitrina robusta. Gould. 

 Gould, Pro. Boston Soc, 1846. 

 Expedition Shells. PL I. Pig. 11. 



Shell helicoid, transverse, depressed and globose, rather strong, 

 polished, very bright, pale yellowish-green, striated with regular, ob- 

 tuse, lines of growth ; spire obtuse ; whorls 3, the last large ; apes 

 sub-central, rounded beneath; aperture rounded, left margin reflected 

 above, forming a small umbilical fissure. 



Breadth A-, axis \ of an inch. From the figure greater diameter 6 - 60 ; 

 lesser diameter 40; alt. - 31 of an inch. 



Habitat. East Coast of Australia. Gould. 



The preceding is Gotdd's description from Pfeiffer, in Brit. Mus. Cat. 

 of Palm., p. 69. It seems to me that this is in no respect different 

 from that named V. Strang ei three years afterwards.
