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. 

 Innately oval ; peristome expanded, slightly obtuse. 



Diam. 4 millim. 



Ono Island. 



Several examples received from the Museum Godeffroy. Possibly 

 only a variety of H. musiva with fine spiral impressed lines. 



Genus Georissa, Blanford. 



1. Georissa juvenilis (Mousson). 



Biancta 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 parta (Pease).

Ilydrocena 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. It is shaped 

 like G. juvenilis, but is a little larger, and the whole surface is 

 smooth and somewhat shining.
