Hurrox.—On New Zealand Land Mollusca. 187 
New Zealand, as 1 have identified nearly all the other of Strange's shells ; 
but Reeve says that it was collected by Cuming, in which case the locality 
is pretty sure to be incorrect. pori 
I have adopted Professor von Martens’ suggestion, that all the specific 
names meaning of, or from, New Zealand should be spelt uniformly, and 
have taken neozelanicus as the most correct. I have also followed him in 
retaining Reeve’s names for those species which Dr. Pfeiffer named after 
letters of the Greek alphabet, as these letters are usually employed for 
varieties, and not used for species. 
I have retained the usual classification, although 1 think that the 
Goniognatha do not form a natural section, but that the genera should be 
distributed among the Aulocognatha. I incline to the opinion that Phrix- 
gnathus, mihi, is near to Punctum, Morse, although the jaws are different ; 
and I expect that Carthea, mihi, is allied to Charopa, Albers, although I 
do not know the animal. 
Tam not aware that the dentition of Endodonta, Charopa, and Amphidoxa 
have been previously described. With regard to Endodonta, the only 
species whose radula I have examined, E. pecilosticta, is not typical, and 
may be wrongly placed. Charopa ida I take to be typical of that genus; 
while Amphidoxa was made to include some species belonging to the 
Aulocognatha, and others belonging to the Agnatha ; and I have chosen to 
associate it with the more numerous group belonging to the first section. I 
have seen no description of the dentition of Thalassia, and refer our species 
to it provisionally. 
The present list comprises 116 species, of which 18 are unknown to me. 
There are also 7 species introduced from England. Of the native species, 
the dentition of 60 has been described by me either in the present volume, or 
in vol. xiv. of the Transactions of the N.Z. Institute; and the animals of 26 
species are described either in this volume or in vol. xv. of the same journal. 
As regards distribution, our knowledge is imperfect; but, so far as is at 
present known, about one half the species are confined to the North Island, 
one quarter to the South Island, and one quarter are common to both. 
Two of the three species from Stewart Island have been found nowhere 
else ; and the single species from Campbell Island is also endemic: but the 
four species said to be found in the Auckland Islands are all natives of New 
Zealand ; as also appear to be both the species recorded from the Chatham 
Islands. The Auckland Islands however possess a peculiar variety. 
Outside the New Zealand Islands Vitrina kermadecensis is found in the 
Kermadec Islands. Therasia ophelia is found in Northern Australia, and 
Paryphanta milligani is Tasmanian. In neither of the two last cases how- 
ever have shells from each locality been compared, and the dentition of all
