3.  DESCRIPTIONS OF S0ME NEW SPECIES OF SHELLS, DISCOVERED DURING THE VOYAGE OF THE RATTLESNAKE.

Relu brumeriensis.  Tab. 2 fig. 1. a, b.

Testa imperforata, globosa-conoidea, crassa, laevigata (sub lente granulato-striata) alba, ad aperturam nigra; spira obtusa, conoidea; anfractus 4, convexiusculi, rapide accrescentes, ultimus basi subcompressus; apertura per-obliqua, oblonga, intus alba; peristoma late reflexum, nigrum.  Diam. maj. 28, min. 23, alt. 23, millem. (Mus.  Brit.)

This remarkable shell resembles a dwarf H. haemastoma in shape; it is of a porcelain white except at the aperture, which has a broad reflexed lip of a deep brown-black hue, both within and without.  It is a very interesting species, indicative of the Indian affinities of the New Guinea fauna.  A single specimen was taken in August 1849, on a breadfruit tree in Brumer Island, South-East coast of New Guinea.

Helix divisa.  Tab. 2 fig. 5. a, b.

Testa obtecte perforata, lenticulari-depressa, orbicularis, carinata, crassiuscula, superne fulva, radiato-striata, minutissime granulata, carina acuta, superne subcrenulata, basi convexa, nitidissima, griseo-albida, radiatim substriata ad umbilicum declivens; spira convexiuscula; anfractus 5, planulati; apertura angulato-lunaris, intus margaritacea; peristoma simplex, basi incrassatum, ad columellam expansiusculum.  Diam. maj. 23, min. 20, alt. 11, mill. (Mus.  Brit.)

A Helix of the Caracolla section, allied to the C. panayensis of Broderip.  Found on the ground at the roots of trees, in the South-East Island of the Louisiade Archipelago.

Helix louisiadensis.  Tab. i. fig. 8. a, b.

Testa imperforata, globoso-turbinata, solidiuscula, sub lente rugosa, albida, fasciis variis purpureo-fuscis ornata; spira conoidea, rubescens; anfrac. 5 convexiusculi, ultimus magnus, paululum deflexus; apertura ovata, intus nitide livida, peristoma expansum, reflexum, sordide violaceum, margine externo sinuato, columellari incrassato, dilatato, subsulcato.  Diam. maj. 26, min. 21, alt. 20, mill. (Mus.  Brit.)

This remarkable snail has a tendency towards a trochi-form contour.  The ground colour appears as a white band on the body whorl marking its most prominent portion just below the centre.  The sinuation of the outer lip and impression of the whorl behind the peristome, give a slightly ringent aspect to the mouth.  It is very distinct from any known species; its affinities are more with Australian than with Philippine forms.  It was taken on a tree in the South-East Island of the Louisiade Archipelago.
