Shell solid, subdiscoidal, convex above. Colour cream. Whorls 

 four and one-half, rather loosely coiled, rounded; the last in- 

 creases rapidly, slightly ascends, and then suddenly descends to 

 its termination. Sculpture : the whole shell is beautifully and 

 delicately cancellated. There are seven spiral cords, two on the 

 shoulder, three on the periphery, one at the margin of the 

 umbilicus and one within it. The upper pair ascend the spire, 

 the lowest peripheral is stronger than the rest. On the last 

 whorl, there are about twenty radials; these ascend the spire, 

 projecting like spokes over the suture. Arising in the sutural 

 trench, they are dormant on the shoulder, are strongly expressed 

 on the periphery, again fade on the base, but revive in the 

 umbilicus, where they project far into the cavity. At the inter- 

 section of the spirals, they form polished knots. A secondary 

 sculpture of fine radial laminae overruns the whole shell. Aper- 

 ture circular, oblique, guarded by a broad outstanding varix. 

 Umbilicus broad and perspective. Height, 5; maj. diam., 7; min. 

 diam., 4*5 mm. 



Following the determination of Angas, this has been locally 

 known as L. clathrata Reeve. But Mr. H. B. Preston, whom I 

 asked to (-ompare the Sydney shell with the type of the reputed 

 Philippine L. clathrata, reported that the two are distinct, that 

 "Z. clathrata has not got the clathrate umbilicus" of the Austra- 

 lian shell. I, therefore, introduce it as a new species. The 

 nearest relations are, perhaps, L. tasmanica Ten. -Woods, and L. 

 suhquadrata Ten. -Woods, which lack the radial sculpture of L. 

 botanica. 



Hah. — Common around Sydney. 



Charisma, gen.nov. 



A new genus related to Liotia, but without a varix to the 

 outer lip, few-whorled, spirally sculptured, umbilicus with an 

 internal funicle. Operculum corneous, concave, multispiral, with 

 a spiral frilled lamella. Type, C. compacta. 



Another member of this genus is C. josephi Tenison- Woods, 

 originally described as a Cyclostrema, transferred, in 1901, by 

 Tate and May to Collonia; in 1902, by Pritchard and Gatliff, to
