Show 314 MR. A. GARRETT ON THE TERRESTRIAL [Mar. 1, growth, and spirally lineated with fine impressed lines; colour yellowish, corneous, with or without radiating reddish spots and bands; spire conoid; suture linearly impressed ; whorls 4|-5, flatly convex, slowly and regularly increasing, the last one depressed, subangulated on the periphery ; base convex ; aperture oblique, lunately oval; peristome expanded, slightly obtuse. Diam. 4 millim. Ono Island. Several examples received from the Museum Godeffroy. Possibly only a variety of IL. musiva with fine spiral impressed lines. Genus GEORISSA, Blanford. 1. G E O R I S S A JUVENILIS (Mousson). Diancta juvenilis, Mousson, MS., Mus. Godeffroy, 1885. "Viti Levu." Shell imperforate, ovate-conical, rather solid, corneous; spire conical, apex obtuse; suture deeply impressed; whorls 5, strongly convex, longitudinally obliquely plicately ribbed ; ribs rude, irregular, becoming more crowded and smaller near the peristome; aperture suborbicular ; peristome simple, straight; columellar region thickened with callus. Length 2| millim. Several examples were received from the Museum Godeffroy. The oblique longitudinal riblets will at once determine this from any other Polynesian species. 2. GEORISSA PARVA (Pease). Cyclostoma parvuni, Pease, Proc. Zool. Soc. 1864, p. 674. Chondrella parva, Pease, Proc. Zool. Soc. 1871, pp. 465, 476 ; Pfeiffer, Mon. Pneum. iv. p. 294 ; Garrett, Journ. Acad. Nat. Sci. Philad. 1884, p. 106, pl. 3. fig. 41. Llydrocena insularis, " Crosse," Mousson, in Museum Godeffroy, 1885. Examples of this species received from the Museum Godeffroy, labelled " Hydrocena insularis, Crosse, Viti Levu," do not differ from Pease's Chondrella parva inhabiting the Society Isles.
