522 MR.G.F.ANGASONSOUTH AUSTRALIAN LAND-SHELLS. [DcC. 8, 



straminea, anguste umbilicata ; anfractibus planis, tenuissime 

 concentrice striatis, ultimo ad peripheriam subangulato ; aper- 

 tura perobliqua, lunato-ovali, latiore quam longa ; labio acuto, 

 breviter rejlexo, mnbilicum vix tegente. 

 Long, g lin., lat. 3 lin. 



Hab. South Australia, under stones and logs {Coll. Angus.). 

 A small species, somewhat resembling H. rustica, Pfr., but with 

 the last whorl subangular at the periphery, and with a narrow um- 

 bilicus, which is nearly concealed by a short reflexion of the colu- 

 mellar margin. 



15. BULIMTJS (LiPARUs) ANGASIANUS, Pfr. 



This fine Bulimus, which is rather more than an inch in height, 

 having the body-whorls handsomely banded with white and brown, 

 belongs to the Western Australian group Liparus, which is repre- 

 sented there by B. melo, B. trilineatus, B. physdides, and others. 



My specimens were obtained from an open heath at Port Lincoln. 

 I possess two dead specimens of B. physoides from Western Au- 

 stralia, and one of B. meridionalis, an East African species, which I 

 obtained on the sea-beach near Port Adelaide. These must probably 

 have been carried thither by the strong westerly winds and currents 

 which prevail durug the winter months. 



16. BULIMINUS (ChONDRULA) ADELAIDE, Ad. & Aug., n. s. 



B. testa turrita, pvpiformi, in medio dilutata, umbilicata, albido- 

 badia ; avfractihus 6, ccnvexis, longitudinaliter strigillatis ; 

 apertura rotimdato-ovata ; peritremate interrupto, albo, late 

 rejlexo ; labio superne callo tuberculiformi albo munito. 

 Long. 3 lin., lat. 1 lin. 



Hab. South Australia, rocky places (Coll. Angas.). 

 A small pupa-like species having all the characters of Chondrida, 

 which it appears to represent in South Australia, where it is gene- 

 rally distributed. In Western Australia there is an allied species, 

 which we have elsewhere described as Chondrula lepidula. 



17. Vertigo australis, Ad. & Ang., n. s. 



V. testa sinistrorsa, apice obtuso, rimato-umbilicata, pallide 

 fuse a ; anfractilms 7, ccnvexis, oblique valde striatis; apertura 

 semiovata, peritremate incrassalo et late dilatato, plica unica 

 parietali et jAica unica columellari munita. 



Long. 2 lin., lat. | lin. 



Hab. Rapid Bay, in crevices of rocks {Coll. Angas.). 



A cylindrical and, for the genus, a large species, with the aperture 

 furnished with but two plicae. 



18. SUCCINEA STRIGATA, Pfr. 



A strongly plicate species with a papillary spire ; pretty generally 

 distributed throughout the coimtry, in barren sandstone places.
