712 STUDIES ON AUSTRALIAN MOLLUSCA, xii., 



Leptothyra; and, in 1908, by Hedley and May, to Liotia. In 

 shell-characters, it is somewhat like Leptothyra, from which the 

 operculum immediately and widely separates it. Isanda is 

 perhaps related. 



Charisma compacta, sp.nov. 

 (Plate Ixxxi., fig.4 9.) 



Shell small, solid, turbinate. Colour pale cream. Whorls 

 four, rather loosely coiled, separated by channelled sutures. 

 Spire-whorls smooth, body-whorl sculptured by about twenty 

 regularly spaced, sharp, spiral grooves. Umbilicus about one- 

 eighth of the shell's diameter, its margin smooth and rounded, 

 the aperture-side with an obscure funicle. Aperture descending, 

 circular, inner lip slightly expanded, outer lip simple. Height, 

 19; maj. diam., 2; minor diam., 1-7 mm. 



Hah. — 100 fathoms, north-east of Port Macquarie (self). 



Compared with Cyclostrema josephi Tenison- Woods,* the 

 novelty is much smaller, more widely umbilicate, comparatively 

 shorter and broader. 



AcM^A inradiata Reeve. 



Patella inradiata Reeve, Conch. Icon., viii., 1855, PI. xxix., 

 figs. 77a, 6; Nacella inradiata Pilsbry, Man. Conch., xiii., 1891, 

 p. 120, PL 20, figs. 43, 44. Aciiuea criicis Ten. -Woods, Proc. Roy. 

 Soc. Tasm., 1876 (1877), p.52, 1877, p.44 : Mscy, op. cit., 1902, 

 p.ll3. 



Mr. Tom Iredale writes to me that ^^ Patella inradiata (Reeve, 

 Conch. Icon, f.77, 1855) is identical with Acmcea crucis Ten.- 

 Woods. Reeve gave no habitat, but the type-tablet in the 

 British Museum is now marked "Tasmania." 



Tate and May {antea, xxvii., 1901, p. 411) reduced A. crucis to 

 a synonym of A. cruciata Linn., and A.Jlammea, Quoy&Gaimard. 

 Mr. May notes that the type of Ten.- Wood's species is in the 

 Tasmanian Museum, but there are also, in the Australian Museum, 

 two specimens presented by Tenison- Woods, and labelled "type 

 Acmcea crucis Tenison- Woods," in iiis own handwriting.
