Melanella Bowdich 1822. Longitudinally volute; the last 
whorl considerably larger than the preceding; turreted, spire

rounded at the apex, small; adult whorls about nine, nearly flat;

l^mm. Bcachport S.A. to Bunbury W.A., beach and down to 
*50 fatlioms. (lype locality — Blackman's Bay, J'asmania). 
Rather variable. Soutli Australian specimens are generally a 
little more attenuate than the type; length of body whorl varies 
in proportitm to total length; the twist on the shell varies, in some 
It is in one I’lane, in others it is a screw curve, due to the lip 
mark on the spire being carried successively a little farther on 
tha nthe pervious one. In Tasmonian specimens the last whorl 
hears a smaller proportion to the spire than in the South Aus- 
tralian shell. 
Strombiformis Da Costa 1778 (— Leinstraca IL k A. Ad-

lo discern the axial pillar through the whorls; interrupted, zig-

cavated. Height .5, diam. 1 mm. Bcachport S.A. to Bunbury

Sr. Vincent. ('Lyr*^ locality — San Remo, Victoria). Tate con- 
fused South Australian spccimen.s under various names, with S. 
})ivitlata Reeve; the ccjlumclia margin is prominent and runs for- 
ward as a sharp edge, while the cnlumeHa of joshua^ta is flat and 
-slightly concave as in Thais: the mouth also is different. S. aru-
