Fam. Phenacohelicidæ.
(2.) Flammulina (Allodiscus) urquharti, Suter.
Distribution,—This minute brown shell is, no doubt, easily overlooked; and, on the other side, it must be mentioned that all the species of the subgenus Allodiscus are not common shells at all. The type was found on Mount Pirongia, and specimens from the Hunua Range are also in my collection. North Island only.
(3.)Flammulina (Therasia) celinde, Gray.
Distribution.—A fairly common shell in the northern parts of the North Island, but has not been found on it further south than the Urewera country. In the South Island it was found in Happy Valley, Canterbury, where also Phenacharopa novoseelandica, Pfr., occurs.
(4.) Flammulina (Therasia) decidua, Pfeiffer.
Distribution.—Found from Auckland to Otago. This is one of the very few New Zealand snails I have seen leaving its hiding-place after a warm rain and crawling up on shrubs with smooth bark, or devoid of it.
(5.)Flammulina (Suteria) ide, Gray.
Distribution.—Occurs over the entire North Island; in moist situations of the bush, and the northern part of the South Island. Its southernmost limit is, to my knowledge, near Lake Mahinapua, where it was found by Dr. A. Dendy.
(6.) Flammulina (s. str.) pilsbryi, Suter.
Distribution.—Like most minute forms, this species is widely distributed over New Zealand, and is found on both Islands. In the South Island I found it near the Mueller Glacier in some native bush
