white, pale yellow or reddish ; spire rather suddenly tapering, ob- 

 tuse, suture slightly impressed, scarcely callous ; whorls 6, four 

 upper moderately convex, rest less so, last in front equalling all 

 the others ; aperture vertical, circular, continuous ; peristome white 

 or pale, thickened, briefly expanded, upper channel rather wide, 

 ascending, in a line with the apex, inwardly bordered by a slightly 

 curved triangular tongue, columellar channel obliquely and out- 

 wardly ascending, the lip partially surrounding its rounded outer 

 orifice, above with a broad triangular, pointed columellar tongue. 

 Length 0-37 ; breadth 0-18 ; aperture 0-10 broad, of an inch.

 Cox, Catalogue of Australian Land Shells, p. 32, 1864. 



Shell oblong-ovate, moderately solid, polished, shining, pellucid, 

 smooth, sometimes very obsoletely striated above under the lens, 

 glassy white or pale reddish-horny ; spire tapering, obtuse, suture 

 lightly impressed and slightly callous ; whorls 6, uppermost mode- 

 rately convex, rest less so, last whorl in front rather exceeding the 

 rest ; aperture nearly round, vertical ; peristome and lingual ap- 

 pendages white, thickened, briefly expanded, upper canal, in the 

 angle of the upper lip, obliquely ascending inwardly, lower canal 

 cutting the columellar margin obliquely, protected above by a some- 

 what quadrate colmnellar tongue, roundly truncate. 



Length - 37 ; breadth 0-20; aperture 0-10 broad, of an inch. 



Habitat. Clarence Biver, New South Wales, under and in decaying 

 logs. Wilcox. Moreton Bay. Bidwill. 



This highly polished beautiful species is closely allied to P. bilinguis. 

 The truncation of the columellar tongue, which I find constant, is 

 the most notable character. 



242. Pupina robusta. Cox. Plate XVI. Pig. 13 natural size, 

 13 a., 13 b. much magnified. M.C. 



Shell oblong-ovate, moderately solid, polished, shining, pellucid, not 

 striated, pale yellowish or reddish-horny ; spire ovately tapering, 

 obtuse, suture thinly enamelled on two lower whorls ; whorls 5 to 6, 

 last in front more than equalling the remainder, penultimate equal 

 to those above ; aperture nearly circular, vertical, produced obliquely 

 outwards ; peristome and auricles white or pale, thickened, expanded, 

 upper channel wide, vertical, bordered by a plate shewing a triangu- 

 lar front, lower channel obliquely cutting the columella much above 

 the centre, and having a small lamella, triangular from in front. 



Length 0*33 ; breadth 047 ; aperture 0*10 broad, of an inch. 



Habitat. "Warro, Port Curtis, Queensland. Blachman. 



Closely allied to P. bilinguis, but smaller and stouter, lip not continuous, 

 and having the line of axis of the mouth much more oblique, and 

 the lower canal higher upon the columella. A very young specimen,
