AUSTRALIAN LAND SHELLS. 51 



Habitat. Lower Murray Eiver, S. Australia, in bushy patches amongst 

 sandstone cliffs. Angas. 



I have taken Pfeiffer's description. Adams and Angas remark oi 

 this shell, that "it is a delicate pale-brown and whitish banded 

 species, somewhat depressed in form, with the outer lip but slightly 

 reflected." 



129. Helix Flindersi. Adams and Angas. 

 Adams and Angas, Pro. Zool. Soc, 1863, p. 521. 



Shell globosely-conoid, rather thin, moderately umbilicated, brownish- 

 white ; whorls 4, rather convex, rugosely striated, last large, in- 

 flated ; aperture lunately-ovate, lip callous, partially covering the 

 umbilicus. 



Length 7 ; breadth 7 lines. 



Habitat. Tillowie, near the western slopes of Flinder's Eange, South 

 Australia. A ngas. 



Mr. Angas, from whose description the preceding has been taken, 

 further says that "this remarkably compact and globose species, of 

 which only two specimens have hitherto been found, is c' aracterised 

 by the rugose strife of the whorls, and by its conoidal spire." 



130. Helix Evandaleana. Pfr. Plate IX. Fig. 18, 18 a. en- 

 larged. M.O. 

 Pfr., Pro. Zool. Soc, 1863, p. 528. 



Shell umbilicated, depressed, rather thin, rugosely- striated, and under 

 the lens granulated and furnished with short hairs, dirty-yellowish 

 or blackish-brown ; spire slightly elevated, obtuse, suture rather 

 deep ; whorls 4, convex, last more or less obtusely carinated ; base 

 convex, the striae and granulations gradually becoming fainter ; um- 

 bilicus moderate, deep ; aperture lunately-ovate ; peristome simple, 

 thin, more or less angular externally, at the columella triangularly 

 dilated above. 



Diameter, greatest 0*55 ; least G"47 ; height 0'30 of an inch. 



Habitat. Evandale, under dead logs. Angas. Barrier Ranges, S. 

 Australia. Masters. 



I have not seen in any other species the same kind of rugose striation, 

 granulation, and pilosity, the last often obsolete, which seems to be 

 characteristic. Angas speaks ofa" large umbilicus," while Pfeiffer 

 writes of the same shell " subanguste urabilicata." 



131. Helix Lincolniensis. Pfr. Plate VI. Fig. 9. M.C. 



Pfr., Pro. Zool. Soc., 1863, p. 527. 



Shell umbilicated, somewhat conoidly-depressed, rather thin and mode- 

 rately glossy, pellucid, very closely, coarsely and irregularly rugosely 

 striated, and finely granulated, of a rich deep-chestnut throughout ; 

 spire slightly elevated, widely conical, obtuse, suture pale ; whorls 5, 

 rather flattened, last rounded, rather depressed above, and some- 

 times indistinctly angular at the periphery, descending in front ; 

 base less strongly striated than above, smoother and more glossy, 

 Umbilicus small ; aperture lunately-ovate ; peristome simple, thin,
