demand the creation of a new genus. ‘This will be attended to in a 
revision of the New Zealand Turridae; in the meantime they may be left 
temporarily in Bela. In connection with this note it may be mentioned 
that Daphnella varicostata M. & M., recently described from the beds at 
wamoa, is a synonym of B. diues Sut. The figure does not show 
the important columellar plaits, and the sutures are more sloping than usual, 
but both these differences (as also those mentioned regarding sculpture, 
protoconch, and suture) can be mate y specimens in my collection 
rom Pukeuri and Target Gully. It is very unusual for the plaits to be 
obsolete, but two of my senile specimens have an almost smooth pillar. 
Probably if the specimens used by Marshall and Murdoch were examined 
they would show this generic feature; it is to be noted that the diagnosis 
contains the words “ columella . with small oblique threadlets 
corresponding vil the adjacent spirals," so that these are probably not 
restricted to the а ec as in the figure. In all other respects their 
shell is a typical senile B. ca

P. pukeuriensis agrees exactly with the Australian Narona group, more

Cossmann, in the Essais, vol. 3, has referred the former of these doubtfully 
to Brocchina, and, apart from this genus, the only other to which these 
shells bear much resemblance is Sveltella. As regards the Australian species 
of this family, both the — given by Tate in the “Census
