oblique stric'C upon the middle whorls ; it is also rather more 

 cylindrical in form than clani. 



Piipiria suhpoUta, sp. n. (Pi. IX. fig. 4.) 



Shill iniporfoiate, oblong-oval, shining, light horn- 

 colour, finely striated by growth-lines ; suture rather deej), 

 narrow ly margined at last half-whorl; whorls 5^, regularly 

 increasing, convex, penultimate as witie as the last; aperture 

 circular ; peristome white, thickened and narrowly expanded, 

 margins joined by a parietal callus, anterior an 1 posterior 

 canals subcircular, the openings as seen from the front being 

 very narrow ; operculum horny, whorls 5, sharply defined by 

 raised spiral ridges, last four about equal in diameter. 



Maj. diain. 3, alt. 5 mm. 



llab. Richmond River, New South Wales {SU. W. 

 Juckson). 



This ."pccies is allied to P. pineticola, Cox, but the latter 

 is smoother, the whorls increase rather more rapidly, are less 

 convex, and the last whorl is rather broadly and distinctly 

 margined at the suture, whereas suhpoUta is only indistinctly 

 and very narrowly margined on the last half-whorl. 



In piyicticoJa the anterior canal cuts much more deeply and 

 widely through the peristome than in subpolita, in which it 

 goes only about halfway through; in suhpoUta the posterior 

 canal is narrower and its direction is slightly to the right, 

 not towards the apex as in jnneticola. 



PupineUa densecostata, sp. n. (PI. IX. fig. 7.) 



Shell rather deeply rimate, oblong-conic; sculptured with 

 close-set raised striae, dirty white colour ; whorls 7, earlier 

 very convex, later ones moderate, slowly and regularly in- 

 creasing ; aperture circular, whitish within ; peristome white, 

 moderately expanded, continuous ; anterior and posterior 

 cnnals circular, both i)iercing deeply into the lip, but not 

 cutting right through. 



^laj. diam. 4^, alt. 11 mm. 



Ilah. Port Curtis, Queensland. 



Closely allied to simplex, Fult. but readily separated by 

 its shorter stouter form. 



PupineUa simplex^ sp. n, (PI. IX. fig. 3.) 



Shell narrowly umbilicated, ovately conic, finely obliquely 

 striated, dirty white colour; whorls 6, moderately convex, 

 regularly increasing; aperture circular, whitish within; peri- 

 stome thickened and slightly expanded, white, continuous;
