some of them described as new; though I do not agree with the 
determinations of a few of them, e.g. —Actcon scrobiculatus, this 
is not the species of Tenison-Woods, but represents A. distingu- 
endus, Cossmann ; Ringicula lactea is not Johnston’s species, but 
is R. Tatet, Cossmann; Leptoconus Newtoni, n. sp., is L. extenuatus 
Tate; L. convexus, n.sp., is L. acrotholoides, Tate; and Drillia 
oblongula, n. sp., is Buchozia hemiothone, Ten.-Woods ( Columbella). 
In Scaphander tenuis and Umbraculum australe, the author fore- 
stalls S. Tatei and U. australensis of Cossmann. Moreover Mr. 
Harris replaces many generic names of long standing by others in 
accordance with the strict rules of priority, or on the ground of 
preoccupation ; as most of such rectifications are generally accepted 
by the leading paleoconchologists, I shall indicate these and other 
proposed innovations in their proper places. 
Class GASTEROPODA. 
Family Muricip#. 
Sistrum, Montfort, 1810, has priority over Ricinula, Lamarck, 
1816. 
Family Lampusip&. 
Triton and Tritonium are names that have been in prior use in 
other departments of zoology, and the application of the priority 
rule by Mr. R. B. Newton has led him to suggest the employment 
of Lampusia, Schumacher, 1817, in which he is followed by Coss- 
mann, 1896; whilst Mr. Harris advocates Lotoriwm, Montfort, 
1810. So also Colubraria, Schumacher, 1817, has priority over 
Epidromus. 
Genus Plesiotriton. 
This genus was instituted by Fischer in 1884, uniquely repre 
sented by Cancellaria volutella, Lamarck, of the Parisian Eocene. 
The form is that of Hpidromus, the canal is short and deeply 
notched, and there are plications on the columella. The type bas 
three principal columellar plaits, but the Australian representa 
tives have only two. I recognise two species in the Eocene strata 
of Australia, namely, Cantharus varicosus, mihi,! from Alding® 
and P. Dennanti, n. sp., from Cape Otway.
