110 LIOTIA. 



L. Angasi, Crosse. PI. 36, fig. 4. 



Moderately umbilicated, strong, solid, light brownish or greyish, 

 with abont five strong revolving series of rounded tubercles, the last 

 defining the umbilicus, peristome tubercularly varicose. 



Diam. 8 mill. 



Port Jackson, Australia. 

 L. sPECiosA, Angas. PI. 36, figs. 5, 7, 8. 



Rather solid, depressly orbicular, pale brown, with three prom- 

 inent spiral ribs, and longitudinally finely, distantly plicate, the 

 intersections nodose, suture excavated, umbilicus moderate, encircled 

 by a rib, its walls decussated with concentric and radiating striae, 

 outer lip a little thickened, with continuous peristome. 



Diam. 2 mill. 



Port Jackson, Australia. 



Notwithstanding some differences in the descriptions, I think this 

 will prove synonymous with the preceding species. 



L. Gowllandi, Brazier (figs. 7, 8) appears to me to be synomymous, 

 judging from description and figure. Mr. Brazier states that it ap- 

 proaches closely to L. speciosa, but does not give distinctive charac- 

 ters. It comes from Percy Isl., N. E. coast of Australia. 



L. ASTERiscus, Gould. PI. 36, fig. 6. 



Solid, brownish white, with about twenty radiating ribs, cut by a 

 subsutural sulcus, another at the periphery and a third around the 

 moderate umbilicus; whorls 4, convex, very minutely spirally 

 striate. Diam. 1*5 mill. 



Hong Kong. 



Figured from a type specimen. Too close to the two preceding 

 species. 



L. siDEREA, Reeve. PL 36, fig. 10. 



Depressed turbinate, with three prominent spiral ribs on the mid- 

 dle of the body whorl, and smaller ones above and below them, 

 crossed by distant, sharp longitudinal ribs, forming nodosely spin- 

 ous intersections, suture deeply channeled, umbilicus very wide, 

 perspective. 



Philippines. 



The peculiarity of the species is its star-like projection of tubercles 

 on the periphery of the whorls. The figure is enlarged, and dimen- 

 sions not oiven.
