374 DR. J. C. COX ON N E W AUSTRALIAN LAND-SHELLS. [June 26, Richmond River, at Cowlong (in cedar-brushes under logs) (Mac-gillivray). This shell bears much general resemblance to specimens of H. mansueta from the Pine Mountain, Lismore, Richmond River (which are darker than Queensland specimens) ; but the pilose surface, the white lip, the narrower and more covered umbilicus are very di­stinctive characters in H. porteri, which is besides closely allied to the more diminutive H. brevipila, and occupies a place between it and H. mansueta. HELIX CONSCENDENS, mihi. M.C. H. testa imperforata, globoso-turbinata, pertenui, pellucida, semi-vitrea, nitidiuscula, sub lente obsolete striata, albida, fascia plus minusve colorata ornata; spira conoidea, apice colorata; anfractibus sex, convexiusculis, ultimo peramplo, paululum de-flexo, carina obsoleta; apertura lunato-ovata; peristomate tenui, margine externo subsinuato, columellari supra tenuiter reflexo. Diam. maj. 0*60, min. 0*50, alt. 0-55 unc. Hab. Lismore, Upper Richmond River (on trees in the pine-brushes) (Macgillivray). The band varies in intensity of colour from deep black bordered with red to reddish brown or pinkish, and in old specimens is very faintly indicated. HELIX FENESTRATA, mihi. M.C. H. testa minute umbilicata, globoso-conica, carinata, tenui, cinereo-fulva, lineis rugosis elevalis plurimis irregulariter cos-tata carterisque spiralibus decussata, speciem fenestratam for-mantibus prarsertim versus apicem ; spira conica, apice obtusa; anfractibus sex, convexiusculis, ultimo subacute carinato ; aper­tura subangulato-lunata, intus margaritacea; peristomate tenui, acuto, ad columellam modice expanso et umbilicum subtegente. Diam. maj. 0*33, min. 0*30, alt. 0*27 unc. Hab. Pine Mountain, Lismore, Upper Richmond River (on trunks of trees) (Macgillivray). HELIX CORTICICOLA, mihi. M.C. H. testa aperte umbilicata, depresso-circulari, nitidiuscula, epi-dermide fulvo-rufescente vestita, penicillis pallidioribus supra irradiata, irregulariter subcrasse costata, infra larviuscula, lineas spirales obsoletas sub lente exhibente; spira depressa; anfractibus quinque, declivi-convexis, pergradatim increscenti-bus, ultimo obtuse carinato, ad os obsolete; apertura lunato-subcirculari; peristomate tenui, simplici, non ad columellam dilatato. Diam. maj. 0*30, min. 0*25, alt. 0*15 unc. Hab. Lismore, north arm of Richmond River (under bark) (Mac­gillivray). Closely allied to H. urarensis.
