{Hyalina) 1870, p. 115 ; Paetel, Cat. Conch, 1873, p. 86 ; Schmeltz, 

 Cat. Mus. Godeff. v. p. 90, 



Helix vitiensis, Pfeiffer, Mon. Hel. v. p. 146. 



Common beneath dead leaves in forests near the sea-shore, and 

 widely distributed through the group. 



A small, umbilicated, depressed, thin, pellucid, pale horn-coloured 

 species, about the size and shape of Hyalina arborea. Say, a North- 

 American species. 



2. ZONITES PLICOSTRIATUS. 



Zonites plicostriatus, Mousson, Journ. de Conch. 1870, p. 116. 



Helix plicostriata, Pfeiffer, Mon. Hel. vii. p. 197. 



Inhabits the south coast of Vitu Levu and Kantavu {Graffe). 



A little smaller than the preceding species, from which it differs 

 in having the body-whorl angulated, and the sculpture consists of 

 fine rib-like strise and spiral impressed lines. 



3. Zonites schmeltziana, sp. nov. 



Shell umbilicated, depressed, orbicular, pellucid, shining, obscurely 

 striated, pale corneous, sparsely speckled with white; spire depressedly 

 convex ; suture slightly impressed ; whorls 5, nearly flat, regularly 

 increasing, last one not deflected in front, depressedly rounded, upper 

 portion depressed and angulated ; base convexly rounded ; umbilicus 

 small ; aperture oblique, orbicular-lunate ; peristome straight, sharp, 

 with remote margins ; columella slightly reflected. 



Major diam. 9, height 4 millim. 



Hab. Malolo Island. 



Common beneath decaying vegetation, in forests near the sea- 

 shore. 



Nearly twice the size of Z. vitiensis ; this species has the spire 

 more depressed, the whorls flatter, and may at once be recognized by 

 its angulated body-whorl. 



Genus Trochomorpha, Albers, 



I. Trochomorpha merzianoides. 



Helix {Trochomorpha) merzianoides, Garrett, Proc. Phil. Acad. 

 Nat. Sci. 1873, p. 237, pi. 3. fig. 72. 



A rare species inhabiting Vanua Levu, where I found a few 

 examples adhering to the trunks of trees. 



Its large size (22 millitn.), honey-yellow base, chestnut- brown 

 upper £,urface, which is mottled with radiating hnes and spots of a 

 luteo\is-white colour, will at once distinguish it. The upper surface 

 is coloured nearly the same as T. merziana, a Solomon-Island species ; 

 but the present species may be separated by the absence of the 

 basal band, darker colour, the narrower last whorl, and its narrower 

 aperture. T. merziana also differs in having the upper margin of the 

 peristome inflected.
