lato : apertura lunato-ovata, margine coliimellari subreflexo 

 umbilicum partim tegente. 

 Long. 5| lin., lat. 10 lin. 



Hub. Port Lincoln, under dead logs (Coll. Angas.). 

 This handsome species is of a rich rufous brown, adorned with a 

 pale band near the sutures. It seems to combine the characters of 

 H. lincolnenbis and H. cassandra. 



9. Helix (Hadra) flindersi. Ad. & Ang., n. s. 



H. testa globoso-conoidali, tenuicula, mediocriter umbilicata, 

 fusco-albida ; anfractibus 4j, convexiusculis, rugoso-strigil- 

 latis, ultimo magna inflate ; apertura lunato-ovata, labio callo 

 ujnbilicum partim tegente. 

 Long. 7 lin., lat. 7 lin. 



Hab. Tillowie, near western slopes of Flinders Range {Coll. 

 Angas.) . 



This remarkably compact and globose species, of which only two 

 specimens have hitherto been found, is characterized by the rugose 

 striae of the whorls and by its conoidal spire. 



10. Helix (Angasella) cyrtopleura, Pfr. 



This strongly plicate, flattened, and widely umbilicated species 

 belongs to a group of which it appears to be the only hitherto known 

 representative. It somewhat resembles H. plicaria of Tenerifl'e in 

 the character of its sculpture ; but the outer lip is narrower and less 

 expanded, and the umbilicus deep and wide. 



Mr. Arthur Adams hns separated this species as belonging to a 

 peculiar group, for which he has proposed the name of Angasella. 



From the plains near Lake Torrens. 



11. Helix (Charopa) juliodea, Forbes. 



This beautiful radiately sculptured and delicate species occurs also 

 in New South Wales, where it is pretty generally distributed. 



Found at Rapid Bay, near Cape Jervis, in the ravines of the high 

 hills bordering on the coast. 



12. Helix (Charopa) murrayana, Pfr. 



A small, flattened, finely plicate species, with a large umbilicus. 

 From under stones and amongst grass in the ledges of the sand- 

 stone-cliffs of the Murray. 



13. Helix (Thalassia) rustica, Pfr. 



A small, vitreous, reddish horn-coloured species, with a very small 

 deep umbilicus. This species is also found in other parts of Au- 

 stralia. 



From Rapid Bay, in the same localities as H. juliodea. 



14. Helix (Thalassia) subangulata. Ad. & Aug., n. s. 



H. testa orbiculato-conoidali, pertenui, pellucida, vitrea, pallide
