Size. — Length, 20 mm. ; breadth, 24 mm. 
Localities. — Altona, Skipton, Kerang, Albert Park Lake 
(Nat. Mus., Melb.) ; Geelong (J. Mulder) ; Chaika Creek

Dillon and P. S. CoUiver) ; Shelford ( J. H. Young) ; Gayfield

Vernacular Name. — Angas’s Little Basket Shell. 
Observations. — Abundant in Victoria and South Australia. 
The shells are frequently covered by a reddish earthy deposit, 
removal of which discloses a straw-coloured epidermis. Ex- 
ternally and internally the colouring is subject to considerable 
variation. Prime describes it as pale orange, and sometimes 
whitish, but specimens before me are rich purple, while others 
are of a distinct pinkish tint, often in bands. Whan records 
C. deshayesi Smith from Colac; not having examined Whan’s 
specimens, I cannot speak with certainty, but, as C. angasi is 
very abundant in this locality and as G. deshayesi is recorded 
from Victoria River and Port Essington, North Australia, 
Whan’s record requires verification. Dali makes C. angasi 
Prime the type of his new section Corbiculina.
