86 AUSTRALIAN LAND SITELLS. 



very faintly striated, rather solid for the genus, dull greenish- 

 olive ; spire rather flattened ; whorls 3, very slightly convex, rapidly 

 increasing, last depressly rounded ; aperture Innately-roundish ; 

 peristome thin, decliningly curved above, regularly arcuate in frunt, 

 columella curved below, and nearly straight above, minutely re- 

 flexed to form an umbilical fissure. 



Diameter, greatest 0"70; least 0-.30 ; height 0-20; aperture 0*40 long ; 

 - 37 broad of an inch.

208. Vitrina inflata. Reeve. Plate XIV. Fig. 1, copied from 

 Reeve. 



Reeve, Cone. Icon. sp. 64. * 



Shell ovately ear-shaped, yellowish-homy, but little shining ; spire 

 small, scarcely emerged ; whorls convex, inflated, thinly arcuately 

 striated ; aperture rather largely openly ovate. 



Habitat. Sydney. Mrs. Cuming. 



Reeve, whose description has been copied, further states, that notwith- 

 standing the close affinity of many species of this form of Vitrina, he 

 is unable to refer the present to any previously described. It has a 

 peculiarly inflated open-mouthed character. Measurements are not 

 given, and the figure is an enlarged one. 



209. Vitrina Mastersi. Cox. Plate XIV. Fig. 12, 12 a. M.O. 



Shell depressed, very thin, smooth, transparent, extremely shining, 

 very finely curvately striated, with a few faint spiral lines, bright 

 golden yellow with occasionally a greenish tinge ; spire very slightly 

 prominent, apex central, suture impressed, narrowly margined; 

 whorls 3, slightly convex, last rather depressed, rounded at the 

 periphery, and rather convex beneath on outer half; aperture 

 diagonal, lunately ovate; peristome simple, right margin slightly 

 dilated above and in front, left rather straightly continuous with the 

 columella, which is strongly arcuate above, the left margin and base 

 membranous and flattened. 



Diameter, greatest 0-55; least 0"38 ; height 0-17; aperture 035 long ; 

 27 broad, of an inch. 



Habitat. Kiama, N. S. W. Masters. 



A delicate bright golden-yellow hyaline shell, allied to V. Strangei, but 

 easily distinguished by being much more depressed, and having half 

 of the base membranous. The animal of this shell is whitish, and 

 not grey as in V. Strangei.

 Vitrina planilabris. Cox, Pro. Zool. Soc, 1865, p. 697. 



Shell ear-shaped, very much depressed, thin, translucent, polished, 

 clothed with an olive-green epidermis, shortly striated, and under 

 the lens are seen a few spiral depressed lines ; spire very small,
