Cyprcea angustata Gmelin, 1791, a Tasmanian species, is rejected. 
Many species were added by Shirley which are not acceptable until confirmation 
is forthcoming, and it may here be noted that Schilder records a number of species 
from “ Sidney ” which would have been better written “ New South Wales.” 
The type of Cyprcea must be tigris Linne, not mappa, as used by 
Schilder, and the new names I have introduced are here itemised : — Thus 
Arestorides is proposed with Cyprcea argus Linne as type, this species being 
included in his group Callistocyprcea provided by Schilder for G. aurantium 
Martyn, and I cannot see much close relationship between these two. Evenaria 
is given to the group, of which I select C. asellus Linne as type, the other 
Australian species associated with it being hirundo Linne, punctata Linne, and 
contaminata Sowerby, though this group may be remodelled. 
For the caputserpentis group I introduce Ravitrona, naming that species 
as type, and including helvola Linne. Schilder has correctly rejected caputanguis 
Philippi but proposed caputopTiidii for shells from Yokohama and Mauritius, 
and suggested the Australian shells regarded as caputanguis might belong to 
this species. All the so-called caputanguis I have yet examined appear to be 
merely variants of caputserpentis, and there is no need at present to recognise 
two species in Australian waters. If later two species can be separated, a new 
name will probably be required for the second one. A series of small shells 
is included by Schilder under the genus Adusta, which has onyx as type. Our shells 
do not correlate well with that extralimital form, and I propose Palmadusta, 
naming clandestina L. as type. To this genus I attach the so-called lutea 
Gronov. and ziczac Linne, while the series xanthodon Sow., pyriformis Gray, 
walkeri Gray will constitute a subgenus Gratiadusta with pyriformis Gray as 
type, and subviridis Reeve may be tentatively here included. The cylindrica 
group is here named Palangerosa, that species being named as type, the three 
representatives being cylindrica Born, subcylindrica Sow., and quadrimaculata 
Gray. The genus Stolida, to which Schilder referred them, was nameless as the
