July 24. 1935. By Bernard C. Cotton and F. K. Godfrey. 
Australia in shell sand, also St. Francis Island. Lives amongst 
seaweed on rocks. (Type locality — Circular Head, Tasmania, 
and King Island). Resembles F. petterdi Crosse, but the color- 
ation and extreme polish are different. This species presents 
considerable resemblance to immature Austrocochlea odontis 
Wood, but the latter has spiral incisions, balances itself on its 
umbilicus (G. legrandi rests firm on its aperture), has a larger 
Foss arm a legrandi Petterd x 30. 
umbilicus and the columella is not so expanded and does not 
cover it so much. As the shell lies on its dorsum, one does not 
look so fully into the mouth of A. odontis. 
Fossarina petterdi Crosse 1870 (= F. situs oni Tenison- 
Woods 1876). Obliquely depressedly globose, umbilicus some- 
what covered, thin, white, smooth, shining, undulately reddish- 
brown spotted; spire plano-convex, scarcely elevated; whorls 
four, very finely and closely striate lengthwise; last whorl much 
Fossarina petterdi Crosse x 20. 
expanded; aperture rounded; outer lip simple; inner lip arcuate, 
dilated posteriorly and produced into a kind of channeled trian- 
gular elevation. Height 6 diam. 9 mm. S.A. speciment illus- 
trated, height 3 diam. 4.5 mm. LJncommon, beach, Glenelg, 
Henley, St. Francis Island. (Type locality— Long Bay, Brum 
Island, Tasmania). 
Nanula Thiele. Small, thin, globose-turbinate, umbilicate; 
whorls convex, rounded; spiral lirulae, regular, fine; last whorl 
large; aperture oblique; outer lip simple, thin. Genotype— 
Gibbula tasmanica Petterd. yP 
Nanula flinders! sp. nov. Shell small, narrowly umbilicate, 
turbinate, rather thin, dull; yellowish, flecked with light brown 
maculations which tend to form indefinite radial stripes, and
