60 AUSTRALIAN LAND SHELLS. 



A variety of smaller dimensions is alluded to by Pfeiffer, from whom 

 the preceding has been entirely taken, Mon. Ilel. Viv., Vol. IV., 

 p. 264. Doubtless a very remarkable and easily distinguished 

 species, from its deep red colour and "mouldy" appearance. 



149. Helix pliculosa. Pfr. Plate IX. Fig. 12. M.C. 

 Pfr., Pro. Zool. Soc, 1856, p. 386. 



Shell umbilicated, turbinately-globose, delicately thin, above closely 

 covered with little folds, diaphanous, slightly shining, reddish- 

 horny ; spire conoid, apex fine ; whorls 5, slightly convex, last sub- 

 angular above the middle, rounded in front, scarcely descending, 

 inflated at the base, somewhat compressed about the moderate, 

 pervious umbilicus ; aperture oblique, lunately-rounded ; peristome 

 white, margins somewhat converging, right slightly expanded, colu- 

 mellar margin dilated above, reflected, and forming with the basal 

 an obtuse angle. 



Diameter, greatest 0'63 ; least 0-51 ; height 0-39 of an inch. 



Habitat, Drayton Range, Queensland. Stutchlury. Rockhampton. 

 Cox. 



I have adopted Pfeiffer's description with very slight alteration, as the 

 only specimen in my cabinet is not in very good condition. Although 

 this shell may be associated with H. aridorum and H. marcescens, it is 

 not granulated. 



150. Helix murina. Pfr. 



Pfr., Pro. Zool. Soc, 1856, p. 384. 



Shell umbilicated, turbinately - globose, thin, regularly striated, 

 granular, somewhat roughened, deep red ; spire shortly conoid, 

 slightly obtuse ; whorls nearly 5, convex, last inflated, scarcely 

 descending in front, somewhat compressed about the moderate, 

 pervious umbilicus ; aperture diagonal, lunately-rounded, pearly 

 within ; peristome brownish, fleshy, everywhere shortly expanded, 

 margins somewhat converging, columellar margin dilated above, 

 reflected in a vaulted manner. 



Diameter, greatest 0-60 ; least - 47 ; height 0'35 of an inch. 



Var. /3. Paler, brownish-horny, with white peristome. 



Habitat, Admiralty Islands. Var. /3. Northern Australia. Stidchbury. 



The preceding has been entirely derived from Pfeiffer, Jlon. Hel. Viv., 

 Vol. IV., p. 267. 



151. Helix morosa. Moreht. 



Morelet, in Journ. de Conchyl., 1853-4, p. 369. Plate XI. Fig. 15. 



Shell with covered umbilicus, turbinately-globose, depressed, thin, 

 plicately striated, granulated under the lens, of a uniform dark- 

 chestnut colour ; spire conoidly-depressed ; whorls 6, somewhat con- 

 vex, gradually increasing in size, the last not descending, base 

 almost flat ; aperture oval, of a uniform colour ; peristome scarcely 

 thickened, shortly reflected, of a violet tint, margins joined by a
