Art. XXII. — On the Land Mollusca of Little Barrier 



Island. 



By Henry Suter. 



[Read before the Auckland Institute, 7th October, 1901.] 



In the Christchurch Press of the 21st November, 1892, some 

 notes on Little Barrier Island were published re the visits of 

 Messrs. Henry Wright and Boscawen, of the Lands Depart- 

 ment, the notes being probably quoted from the Neiu Zea- 

 land Herald. There occurs the following passage: "He 

 (Mr. Boscawen) also found the pupurangi, or New Zealand 

 snail {Helix busbyi), which is about 4 in. or 5 in. long, and 

 lays an egg like that of a bird." It is curious that Mr. Shake- 

 spear, the curator of Little Barrier Island, has never found 

 this large snail, nor has Mr. Cheeseman, on his repeated visits 

 to the island, come across it. Possibly Mr. Boscawen's speci- 

 men was "the last of the Mohicans." Be this as it may, the 

 fact remains that up to the end of the last century nothing 

 else was known about the land molluscan fauna of Little 

 Barrier Island. 



In January last Mr. J. Adams, of the Thames, was paying 

 a visit to the island, and, knowing him to be a very good 

 collector of land-shells, I asked him to have a good look out 

 for these mostly minute and inconspicuous creatures. On Mr. 

 Adams's return he kindly handed over to me the harvest of 

 his collecting, which enables me now to publish the first list 

 of land-shells from this our native reserve. To Mr. Adams I 

 wish to express my gratitude for the great trouble he has 

 taken to get this nice and interesting collection together. No 

 new species were amongst these shells, which belong to four 

 genera and represent twelve species. There is little doubt but 

 that further collecting will produce many additions to the list. 



Fam. KHYTIDIDjE. 

 (1.) Rhenea coresia, Gray. 

 Distribution. — North Island only, but more common in 

 the northern part of it. It is not uncommon in the bush 

 near Auckland, and occurs also on Chicken Island.
