This species occurs abundantly on the ground in damp forests, 

 and oviposits among dead leaves and under decayed Avood. Its 

 eggs are white and globular. The animal is pale cinereous, darker 

 above, with microscopical dots of a dingy hue along the sides of 

 the foot. During locomotion the foot equals in length two di- 

 ameters of the shell, and is narrow, somewhat compressed and 

 pointed behind. 



The shape of the shell is very much like N. casca, Gld., but 

 may be readily distinguished from that species by its constant 

 sutural band, smoother surface and more swollen body. The 

 locations are also remote. The colors and markings are like 

 JV. G-odejfroyana, nobis. 



This species is dedicated to Mr. Theodore Hoyt, whose valua- 

 ble assistance in my researches in the Viti Group I most grate- 

 fully acknowledge. 



Nanina tknella, Garrett. Plate 19, fig. 7. 



Shell globosely depressed, thin, hyaline, glossy, pellucid, lines 

 of growth obsolete, whitish horn-color ; spire widely conical, ob- 

 tuse ; whorls 6J, convex, the last swollen, large, subangulated 

 at the periphery ; suture margined ; aperture oblique, roundly 

 lunate, nearly as long as broad ; peristome thin, simple, slightly 

 sinuous ; columella slightly expanded over the small umbilicus. 



Height, 11 mill.; diam., 17 mill. 



Habitat, Kioa Isl., Viti Isles. (Coll. Garrett and Philad. Acad.) 



A delicate species, not uncommon at the above locality, where 

 they were found lurking among dead leaves and under rotten 

 wood. A few examples were gathered on the contiguous coast 

 of Vanna Levu. It is more depressed, thinner and paler than 

 N. casca. 



Nanina Otare^e, Garrett. Plate 19, fig. 8. 



Shell perforate, turbinately globose, rather thin, subpellucid, 

 glossy, fulvous brown ; spire obtuse, depressly conoid ; whorls 

 6^, convex, the last one large, swollen, somewhat flattened above 

 the periphery, obliquely coarsely striated, striae most conspicuous 

 next the suture, rarely with spiral impressed lines; base smoother, 

 more glossy than above, with a large round creamy-white patch 

 surrounding the umbilicus ; aperture diagonal, nearly as long as 

 broad, lunately rounded, bluish-white within ; peristome thin, 

 simple, slightly sinuous; columella reflected, covering half of the 

 umbilicus. 



Length, 22 mill.; diam., 29 mill.
