806 MR. J. BRAZIER ON AUSTRALIAN LAND-SHELLS. [NoV. 5, 



1868. Helix (Geotrochus) dupuyana, Cox in Monograph of 

 Australian Land-Shells, p. 66, pi. 2. fig. 5. 



1852. Helix dupuyana, Reeve in Conch. Icon. sp. 354. 



Hub. Ash Island, Hunter River, Wingham, Manning River, 

 Scone, New England, Port Macquarie, Macleay, Nambuccra, and 

 Bellengen rivers, New South Wales {coll. Brazier). 



Specimens from the Bellengen are very large, a few that I col- 

 lected measuring 1/ lines in the greater diameter, and 13 lines in 

 the lesser. A variety is also met with of a dark dirty yellow colour, 

 with a dark chestnut band on the periphery. The specimens from 

 the other localities are of smaller size and of a dark chestnut 

 colour. At Port Macquarie it is found on high hills near the sea, 

 under logs. 



6. Helix (Callicochlias) coxi. 



1864. Helix forbesii, Cox, Proc. Zool. Soc. p. 40 (non Pfr.). 



1864. H. cerea, Cox, Cat. Austr. Land-sh. p. 36 (non Gould). 



1866. H. coxi, Crosse, Journ. de Conch, p. 195. 



1868. H. cerata, Cox, Monograph of Australian Land-Shells, 

 p. 58, pi. 8. fig. 4. 



Hab. Port Molle and Port Denison, Queensland (coll. Brazier). 



The ground-colour of this species is white ; the epidermis is 

 remarkably thin ; and the shell has a waxy and rather glossy ap- 

 pearance, especially underneath. Found in great numbers on the 

 trunks of the native fig-trees. 



7. Helix (Conulus) umbraculorum. 



1864. Helix umbraculorum, Cox, Cat. Austr. Land-sh. species 

 136. 



1864. Helix wilcoxi, Cox, Proc. Zool. Soc. p. 594. 



1868. H. wilcoxi, Cox, Monograph of Australian Land-Shells, 

 p. 9, pi. 4. fig. 12. 



Hab. Clarence and Richmond rivers (Macgillivray) ; Macleay 

 River, also Lassey's Island, Bellengen River, New South Wales 

 (Brazier). 



The first name given to this species Dr. Cox singularly ignores ; 

 and in his Illustrated Monograph there is no mention of its being a 

 synonym. In the Proc. Zool. Soc. 1867, p- 723, we have the 

 H. umbraadorum mentioned by him as being allied to H. turricu- 

 lata, Cox. 



8. Helix (Charopa) midsoni. 



1871. Helix (Discus) atkinsoni, Cox in Legrand's Collections 

 for Monograph of Tasmanian Land-Shells, species 62, pi. 2. fig. 12. 



Hab. Brown's River, Tasmania (coll. Cox). 



The change in the specific name is necessary, as Theobald de- 

 scribed an East-Indian species in Journ. As. Soc. Bengal, 1859, 

 under the name of H. atkinsoni. I have named it after Mr. 

 Midson, an enthusiastic collector in Tasmania.
