REMARKS ON THE SOUTH AUSTRALIAN HELICES, 

 WITH A NOTICE OF ALL THE SPECIES KNOWN UP 

 TO THE PRESENT DATE. 



By GEORGE FRENCH ANGAS, F.L.S., C.M.Z.S., F.R.G.S., &c. 



Prior to the year i860, when I first commenced searching for 

 land shells in the province of South Australia, only six of the species 

 of Helix found there were described, and these were all, (except 

 one) species which occur in other parts of Australia, viz: — Helix 

 Stutchbnryi, Pfr., H brevipila, Pfr., H juloidea, Forbes, H rustica, 

 Pfr., and //. confusa, Pfr. 



During a residence in the colony of three years, I was enabled 

 to add eleven more species, which were described from my speci- 

 mens by Pfeiffer, Crosse, Arthur Adams, and myself. When Dr. 

 Cox, of Sydney, published his "Monograph of Australian Land 

 Shells" in 1868, he swelled the list of South Australian Helices to 

 twenty-two, by the addition of five other species, described by him- 

 self. Since then I have been able to add six more species, thus 

 making the total number twenty-eight. They are as follows :— 



1. Helix rustica, Pfr. in Zeit-schrift fur Malac. 1852. 



2. Helix Waterhousei, Cox, Monog. 1868. 



= H subangulata, A. Adams and Angas, Proc.Z.S., 1863. 

 The name was altered by Cox, it having been preoccupied 

 for a Tasmanian species in 1854. 



3. Helix penolensis, Cox, Proc. Z.S. 1867. 



Penola, South Australia. 



4. Helix albumenoidea, Cox, Mon. Aust. Land Shells 1868. 



Flinders' Range. 



5. Helix Murrayana, Pfr, Proc. Z.S. 1863. 



Cliffs of the Lower Murray. 



6. Helix Adelaidas, Pfr. Proc Z. S., 1856. 



Near Adelaide. 



7. Helix retepora, Cox, Proc. Z.S. 1867. 



Flinders' Range. 



8. Helix Morti, Cox, Cat. Aust. Shells 1864.
