PACE: ON THE COLUMBELLID.E. 41 
REFERENCE LIST OF SECTIONAL NAMES. 
Although it 1s not now my intention to discuss the classification 
of the Columbellide, it may be of advantage to give the following 
list of the sectional names which have been associated with supposed 
members of the family, and to define the type-species of each group. 
Where no type has been specified by the author, or selected by 
a later writer (from the species originally enumerated by the author 
of the section), I have recorded the first species mentioned in the 
original list, and this should, in future, be regarded as the type. 
Names printed in italics must certainly be removed from service in 
the Columbellidee, while most of those remaining are, in my opinion, 
of very little value. 
Sections of which the type-species are fossil are marked f. 
All matter printed within inverted commas is to be regarded as 
a direct quotation; that within square brackets as having been 
supplied by the author of the present paper.

Gould, after describing this as a genus ‘intermediate between 
Mitra and Columbella,” goes on to say that it ‘‘ plainly belongs 
to the Amphiperaside.”’ "This discrepancy is obviously due to the 
accidental inclusion in the diagnosis of a parag1 ‘aph ‘referring to 
another genus, apparently C ithe, which is the next in order.
