referred Anarithma metula to Clavatula, Pease referred Seminella varia to 
Cythara, and von Martens referred Columbella marquesa to Daphnella. Dall 
noted that Swvuatieriu, though referred to the Pleurotomide, is obviously 
an Anachis. Tate remarked that the Tasmanian fossil Mangelia grucilirata 
belongs to Colwmbella. The species of Iredulea have been distributed 
through several genera. Their very solid but narrow shell is sculptured 
by numerous slender and continuous riblets; a brown band on the periphery 
is a usual feature. 
Besides those species here recorded as Australian I suggest the in- 
clusion in this genus of the following exotic forms :—Plewrotoma acwminata 
Mighels, Drillia minutissima Garrett, D. pygmea Dunker, D. themeropsis 
Melvill and Standen, D. wanthoporphyria Melvill and Standen, Mangilia 
thalyera Melvill and Standen, and M. theoteles Melvill and Standen.
