South Australian Shells. 
are more pronounced on the periphery; spire very short, sutures 
impressed; whorls four-and-a-half, rounded, sculptured with spir- 
al lirae which are close and weak; last whorl rounded at the 
periphery; basal lirae more distant; aperture oval, outer lip 
simple, columella regularly concave; umbilicus very narrow. 
Holotype, height 3.75 diam 3.8 mm. Locality — Gulf St. Vin- 
cent, dredged 6 fathoms. (Reg. No. D 1 1433 S.A. Mus.) Also 
dredged, Beachport, 40 and ISO fathoms; Cape Borda, 62 fath- 
oms; St. Francis Island, beach and dredged from 6 fathoms. 
West Australia — Bunbury, 10 fathoms. The South Australian 
shell differs from G. t as manic a Petterd, (type locality, Brown 
River, Tasmania) in being smaller and more depressed; the 
spire is much smaller and shorter in comparison with the body 
whorl. 
Nanula galbina Hedley & May 1908. Galbina signifies 
greenish-yellow. Depressed-turbinate, broadlv umbilicate, trans- 
lucent, glossy; colour variable, either uniform, buff, uniform white, 
or brown spirals on a white ground; whorls four-and-a-half, 
rounded base, subangled periphery, flattened above and impress- 
ed at the suture; protoconch smooth, then two spiral keels in- 
creasing by intercalation to many close fine spirals on the last 
whorl, though they decrease in relative importance; growth lines 
faint; aperture oblique, angled above, rounded below; outer lip 
simple; columella expanded; umbilicus deep, narrow, spiral, ex- 
ternally funicular. Height 5.5 diam. 7 mm. Several specimens, 
dredged Beachport 110 fathoms, Cape Jaffa 130 fathoms. (Type 
locality Port Kembla, N.S.W., 63-75 fathoms). The species is 
nearest to G. f Under si Cotton & Godfrey of which it may be re- 
garded as the deep water representative. G> galbina is thinner, 
Nanula f Under si sp. nov. x 6. 
Nanula galbina Hedley & May x 5.
