This beautiful snail is of a brightly shining yellowish or greenish horn colour.  The whorls of its spire are small, but the body whorl, whilst preserving a wide diameter throughout, gradually increases in trumpet-like manner to the round mouth.  It belongs to the same group with H. olivetorum and H. nitida, and is allied to the Australian H. ptycomphala.  It occurs about the roots of trees in the Frankland and Lizard Islands.

Helix iuloidea.  Tab. 2 fig. 4. a, b, c, d.

Testa late et perspective umbilicata, orbicularis, superne depressa seu subconcava, rufo-cornea, regulariter costulata; anfractus 4 1/2 convexiusculi, ultimus tumidus, rotundatus; apertura lunaris; peristoma simplex, acutum.  Diam. maj. 4 1/2, min. 4, alt. 3 mill. (Mus.  Brit. & Geol.)

This curious little snail, resembling a rolled-up Iulus, and reminding us of our own H. rotundata and its allies, was found under a stone at Port Molle.

Helix inconspicua.  Tab. 2 fig. 3. a, b, c.

Testa perforata, depresso-convexa, laevigata, nitidiuscula, pallide cornea, basi subcompressa; anfractus 6, planiusculi; spira obtusa; apertura lunaris; peristoma rectum, simplex, margine columellari reflexo:  umbilicus minutus, subobtectus.  Diam. maj. 8—­min. 7—­alt. 5 mill. (Mus.  Brit.)

A very inconspicuous ordinary-looking little shell, its upper surface recalling the aspect of H. alliaria but with more convexity and no lustre, and its base that of H. crystallina.  It was found, apparently gregarious, under dead leaves in an islet in Trinity Bay.

Balea australis.  Tab. 2 fig. 9. a, b.

Testa dextrorsa, rimata, subcylindracea, turrita, decollata, dense capillaceo-costulata, corneo-lutea, maculis obscuris flavidis; sutura impressa; anfractus 11, convexiusculi; apertura pyriformis, columella triplicata, plica inferior maxima, conspicua, elevata, acuta, spiralis; peristoma continuum, solutum.  Long. 18—­Diam. 4—­Apert 4 mill. (Mus.  Brit. & Geol.)

This very remarkable shell, the first of its genus discovered in Australia, differs from all its congeners.  It has exactly the aspect of a Clausilia, but the mouth is not furnished with a clausium.  It was found under stones at Port Molle.

Pupina grandis.  Tab. 2 fig. 10. a, b, c, d.

Testa ovato-subcylindrica, superne laevigata, inferne rugulosa, sordide-rufa; spira obtusa; anfractus 6, secundus tumidus, obliquus, ultimus super aperturam planatus; apertura rotundata; peristoma laete aurantiacum, rimatum, crassum, dorsaliter canaliculatum, infra columellari, profunde sinuatum et in canali contorto excavatum; canalis alter minutus ad partem superiorem et externam aperturae; callus columellaris expansus, appressus.  Long. 30, Diam. 15, Apert. 7 mill.  (Mus.  Brit. & Geol.).

This, the giant of its genus, is perhaps the most remarkable land-shell discovered during the voyage.  It differs from all other Pupinae in having an unpolished surface.  It was found in the South-East Island of the Louisiade Archipelago, under dead leaves chiefly about the roots of trees.
