256 ON SOME LAND SHELLS COLLECTED IN QUEENSLAND. 



wehhi Pilsbry,* which immediateh' succeeds T. dunkiensis north- 

 wards. Indeed, another variety, H. funiculata Pfr., from Torres 

 Straits, is not always easy to separate from T. dunkiensis. 



Chloritis jacksoni, sp.nov. 

 (Plate v., figs. 13, 1 4, 15, 16.) 



Shell of moderate size, depressed turbinate, perforate, very thin. 

 Colour uniform burnt umber. Whorls four, rounded, parted by 

 deeply impressed sutures, last a little broadened. Spire elevated 

 periphery rounded. Sculpture(fig.l 6): first whorl and a half 

 coarsely granulate, subsequent whorls with numerous small, rather 

 irregular riblets, which continue with a backward sweep from the 

 suture to the umbilicus. Upon these and their interstices are 

 very small and scattered hairs, easily denuded, and so visible 

 only on fresh specimens. Aperture simple, lip thin, scarcely 

 reflected except near the umbilicus, the margins united by a thin 

 sheet of callus. Umbilicus narrow^ rather oblique. Major diam.. 

 13-5; min. diam., 10; height, 8 mm. 



This species may be distinguished by the coarsely grained apex, 

 followed by the fine radial ribbing. Helix pliculosa Pfr., which 

 I have not seen, would, from the description, appear to resemble 

 this. 



Hab. — Mr. Sidney W. Jackson, to whom I have the pleasure 

 of dedicating this species, found numerous specimens under logs 

 in Ironbark forest-country, at Tolga, south-west of Cairns, in 

 December, 1908. 



Chloritis inflkcta, sp.nov. 



(Plate iv., figs.9, 10. 11; Plate v., fig.l2.) 



Shell of moderate size, rather solid, globose-turbinate, imper- 

 forate. Colour : cinnamon on the spire darkening to chestnut on 

 the last whorl, the reflected lij) bufi". Whorls four and a half, 

 rounded, separated by deeply impressed sutures, last suddenly 

 and considerably descending at the mouth. Spire elevated, 

 periphery rounded, base inflated. Sculpture: the first whorl and
