THE LAND MOLLUSCA OF STEWART ISLAND. 
By Henry Suter. 
Read 9th April, 1897. 
Ix March of this year Mr. Aug. Hamilton, of Dunedin, paid a short 
visit to Halfmoon Bay, Stewart Island, when he collected a number of 
land-shells, which he kindly sent me for investigation. 
Hitherto only four species of land-shells have been known from this 
island, viz. : 
1. Flammulina (Phacussa) fulminata, Hutton ; 
2. Flammulina (Pyrrha) cressida, Hutton ; 
3. Laoma (Phrixgnathus) celia, Hutton ; 
4. Rhytida australis, Hutton ; 
of which the first and last mentioned are endemic. 
Mr. Hamilton’s collection comprised the following species :— 
1. Flammulina perdita, Hutt. One dead and partly broken shell. 
This species is found over the whole of New Zealand, but is a rather 
rare shell. 
_ 2. Flammulina Feredayi, Suter. Two specimens, which correspond 
exactly with my type-specimen from the Forty Mile Bush, North 
Island. The species has also been found on the Hunua Range and in 
the Otaki Gorge, North Island. The var. glacialis I established on 
specimens found in the Hooker Valley, South Island. 
3. Flammulina (Phenacoheliz) granum;Pf. Two specimens, which 
are not adult, having only four whorls and a diameter of 2°5 mm., but 
otherwise differing in no respect from specimens I have from the 
North Island. I have not seen it yet from the South Island. This is 
one of our very rare shells. 
4. Flammulina (Phacussa) fulminata, Hutt. Five specimens, mostly 
bleached. Two of them exceed the dimensions given by Captain 
Hutton for this species, 
(5. Flammulina (Thalassoheliz) igniflua, Reeve, var. obnubila, Reeve. 
Fight specimens, bleached. They are much smaller than the typical 
L. igniflua, with diam. 7, alt. 4°5mm., whorls 43. I found similar 
living specimens near Dunedin, and hence I think it advisable to 
follow Pilsbry (Man. Conch., ser. 1, vol. ix, p. 13), and to distinguish 
them as var. obnubila, although they differ from the type only in size. 
I have not seen this variety from any other part of New Zealand. 
6. Endodonta (Charopa) bianca, Hutt. Two specimens only, which 
do not differ from the typical form. Occurring over the whole of 
New Zealand. 
7. Endodonta (Charopa) tapirina, Hutt. One young specimen, in 
the colour-markings resembling specimens from Otago.
