This fine large ground-species is confined to Kandavu Island, 

 where it appears to be abundant. 



Though subject to considerable variation in size and shape, it 

 may, however, be distinguished by its rather slender form, whitish 

 horn-colour beneath a yellowish or olive-brown ejiidermis, which is 

 sometimes ornamented with waved or zigzagged stripes. The surface, 

 though coarsely striated with lines of growth, is seldom marked by 

 transverse corrugations. The auriculate-shaped aperture is narrow, 

 white, though sometimes tinted with fulvous, and the white lip is 

 considerably expanded and slightly reflected and frequently con- 

 tracted above. Length from 52-77 millim. Like all the ground- 

 species, it is very frequently decorticated. 



6. Placostylus kantavuensis. 



Bulimus kantavuensis, Crosse, Journ. de Conch. 1870, p. 250; 

 1871, p. 105, pi. 5. fig. 3 ; 1875, p. 10 ; Pfeiffer, Mon. Hel. viii. 

 p. 29. 



This is also a terrestrial species, and inhabits Kandavu Island, 

 where it was discovered by Mr, Brazier. 



It is described as a rather solid, cylindrically-fusiform species, 

 with longitudinal rugose striae and obsolete submalleations. Colour 

 ruddy white, with reddish apical whorls. The epidermis is olive- 

 yellow, with longitudinal waved whitish stripes. Tiie last whorl is 

 subcylindrical, compressed on the middle, and the auriform aperture 

 and the widely expanded peristome are whitish. Length 43 millim. 

 I have never seen an example of this species. 



7. Placostylus koroensis.

 Journ. de Conch. 1875, p. 9, pi. 1. fig. 5; Schmeltz, Journ. des 

 Mus. Godeff. Heft xii. 1876, p. 161. 



Placostylus koroensis, Schmeltz, Cat, Mus. Godeff. v. p. 92. 



Occurs in great profusion on the ground in the central valleys of 

 Koro Island, where it is peculiar. 



It is very closely allied to the preceding species, which it resembles 

 in shape and sculpture. Colour corneous or tawny yellow, with a 

 white or luteous aperture and rather widely expanded white peri- 

 stome. Length 53 milHm. It is very frequently distorted and very 

 seldom exhibits traces of a fulvous epidermis, which is disposed in 

 irregular longitudinal strips and patches. Examples sent to Mr. 

 Crosse were, by that learned conchologist, regarded as distinct from 

 his B. kantavuensis.
