ia has been divided generically by Iredale (6a): O. ica 
Sut. remains in Odostomia, but O. rugata Hutt. should be Pyrgulina rugata 
(Hutt.), and O. pseudorugata M. & M. should accompany it here. — 
Surcula, Tornatina, Tritonidea, and Volvulella should respectively be 
Turricula (6c), Retusa (6b), Pollia (6a), and Rhizorus (6b). 
Suter’s usage of the name Hemiconus ornatus (Hutt.) being illegal (26), 
* 
Venericardia pseutes Sut. should be V. awamoaensis Harris (26), and the 
record of V. difficilis (Desh.) should be expunged, being based on juveniles 
var. 
The shell identified as Cantharidus tenebrosus A. Ad. is not that species, 
but a new one, closer to C. sanguineus Gray. 
The type of Crepidula striata (Hutt.) is lost, and the species indeter- 
minable ; the shells classed under that name should be C. radiata (Hutt.) 
(26) = Hutton’s Pilaeopsis radiatus. The forms recorded as C. costata 
(Sow.) belong in some cases to C. radiata (Hutt.), in others to a species 
easily separable from the Recent C. costata (Sow.), and this name ‘should 
be omitted. О. incurva Zitt. (which is not identical with C. gregaria Sow.)

imilarly, the Recent Fusinus spiralis (A. Ad.) is not a member of the 
Target Gully fauna, the species occurring there being referable to F. dentatus 
(Hutt.), which should not be treated merely as a subspecies of F. spiralis. 
The occurrence of F. climacotus Sut. is doubtful.

events, only the latter species should be admitted to the lists from the 
Awamoan localities here diseussed 
. .*Bince treating of this species (26) I have discovered that the name Conus trailli 
is also preoccupied, by A. Adams (Proc, Zool. Soc., 1855, p. 121). I now propose for 
the New Zealand Tertiary species the name Cenospira bimutata nom. nov. The shell 
disagrees radically with Hemiconus, and is best left where Suter originally placed it.
