AUSTRALIAN LAND SHELLS. 103 



thickened, upper canal covered by a large curved triangular tongue, 

 inferior larger at the lower columellar margin, formed above by the 

 large roundly truncate termination of the columella, and below by 

 the lip, both of which margins are prolonged upon the back of the 

 whorl like parallel and somewhat diverging walls. 



Length - 30 ; breadth 0-16 ; aperture - 06 broad, of an inch. 



Habitat. Fitzroy Island, N. E. Coast of Australia. MacGillivray. 



This remarkable species is so unlike any other Australian Pupina that 

 it need never be confounded with them.

 Dohm, Pro. Zool. Soc, 1862, p. 183. 



Shell narrowly ovate, pupiform, smooth, polished, shining, glassy, 

 translucent, white to very pale yellowish or reddish ; spire ovately- 

 conical, obtuse ; whorls 5, suture scarcely impressed, callous, sub- 

 margined, last in front equalling ^ of length ; aperture slightly 

 diagonal, the lower margin being advanced, circular ; peristome 

 white, thickened, very slightly expanded, upper canal viewed in 

 front with an acutely triangular tongue, lower very narrow, 

 obliquely cutting the centre of the columella, and bordered above by 

 a rather broad truncately rounded auricle. 



Length 0'22 ; breadth 0*10; aperture 0'05 broad, of an inch. 



Habitat. "Eocky Isle," off Cape Flattery. Lizard Island, and Cape 

 York, N. E. Coast of Australia. Darnley Island, Torres Straits. 

 MacGillivray. 



The smallest Australian species, which is said by Dohrn to differ from 

 P. Strangei, to which it is closely allied, in the parietal lamella 

 (acute, entering), the oblique aperture, the callous suture, &c. It 

 may be here mentioned that after examining the opercula of all the 

 previous species of Pupina I found nothing abnormal.

 Pfeiffer, in Make. Bl., 1854, p. 90. 



Shell pupce-form, very thin, pellucid, very shining, pale horny ; spire 

 swollen, conical towards the top, somewhat acute ; suture not callous ; 

 whorls 5 \, convex, last contracted, scarcely projecting beyond the 

 base of the axis ; aperture sub-circular, bicaniculated ; parietal 

 callus slightly prominent, on both sides ending in a very small acute 

 tooth, separated by the narrow channels from the shortly reflected, 

 somewhat thickened peristome.
