PREFACE.

The following List of the indiginous Land Snails of New
Zealand is intended to supplement the Catalogue of the
Marine Mollusca already issued by the Department. It is
merely a collection of published descriptions by various
authors, and for the greater part of the work the Department
is indebted to the kind assistance of Dr. Cox and Mr.
A. W. Scott, of Sydney, the latter gentleman having extracted
and translated most of the descriptions from the following
works, which could not be obtained in this Colony :—
“Monograpliia Heliceorum Viventium,” Pfeiffer, 6 vols., 1868,
Leipsic; and “ Monograpliia Pneumonoporum Viventium,”
Pfeiffer, Vol. I., Supplements 1 and 2, 1865.
