9 
of them (19) were found on the coast of the North Island, and of 
these 9 come from its northernmost part (localities 1—5), which 
seems to have been but little explored. At Auckland Island 6 new 
forms were dredged, from Campbell Island 4 are described and 
from Stewart Island 1. Beside these new species there are added 
6 species new to N. Zealand, which belong to the E. Australian 
and Tasmanian fauna. 
Three new genera have been created (viz. Liracraea, Runcinella, 
Neogaimardia), and 7 previously extra-zealandian genera are now 
recorded from the Dominion, viz. Fossarus, Prosipho, Fleterocithara, 
Asperdaphne, Eucyclotoma, Cerithium, and Spaniorinus. Liracraea and 
Runcinella are endemic genera; the latter is most nearly related to 
the Atlantic and Mediterranean Runcina; Fossarus and Neogaimardia 
are common to the Peronian region of E. Australia and Tasmania, 
and the latter is not known outside of this region. Fleterocithara 
and Asperdaphne have recently been created (1922) by Hedley for 
Australian Turrid genera; Eucyclotoma Bo et tger, also accepted 
by Hedley, and Cerithium have a wide Indo-Pacific range. Pro¬ 
sipho is subantarctic, and Spaniorinus, constituted by Dall 1900, 
comprises only fossil forms from the Tertiary of N. America and 
Europe. 
Three families previously not represented in the New Zealand 
fauna are added here: Fossaridae (for Fossarus, of which 4 new 
and one known species are reported), Runcinidae (for Runcinella) 
and Galeommatidae (for Spaniorinus). 
As to the nomenclature, which offers great difficulties and is 
still in a State of confusion, I have followed Suter in all cases 
where his names have not been subsequently corrected or changed, 
according to nomenclatorial rules. A revision has proved to be 
necessary, and, above other authors, I red ale has fulfilled this 
task with his “Commentary on Suter’s Manual of the New Zea¬ 
land Mollusca”, which forms a valuable and indispensable comple- 
ment to Suter’s work. Iredale’s corrections were accepted in 
this paper, whenever they had been clearly proved to be well 
founded and inevitable from nomenclatorial or systematical points 
of view. In some cases, however, I have thought it better to 
keep the old names of genera, until convincing reasons for a change¬ 
ment shall have been adduced. Subdividing and nominating at
