Size of average specimen. — Diam., 11; alt., 6 5mm. 



Type Locality. — Terres Australes. 



Observations. — A smooth, sinning species of common occur- 

 rence throughout Victoria, and appears to prefer damp conditions 

 under decayed timber. Reeve (toe. cit.) remarks "Distinguished 

 chiefly by its narrowly produced transverse form." Its golden- 

 yellow colour is fairly constant but specimens from Lilly Pilly 

 Gully, Wilson's Promontory are much darker — approaching 

 chocolate-brown. 



Locality.— 1 specimen (F 1893) Wombargo Creek (4,000ft.) 

 collected on damp Southern Wollybutt hillside. 



Helicarion sp. f (aff. H. cuvieri Ferussac). 



Size of Type.— Maj. diam., 14-0; Min., 110; alt., 6 -0mm. 



Locality. — 1 specimen (F 1897) Honeysuckle Track, Gelantipy. 



Observations. — One specimen taken alive showing points of dif- 

 ference with H. cuvieri, particularly as regards the animal. We 

 are awaiting further examples to assist in our diagnosis.
