convexity of the whorls, more or less open columellar chink, and in 

 texture vary from thin pellucid to thick opaque cretaceous without

Genus Partula, Ferussac. 



1. Partula lirata. 



Partula lirata, Mousson, Journ. de Conch, 1865, p. 136. pi. 14. 

 fig. 4; 1870, p. 126; Heynemann, Malak. Blatt. 1867, pi. i. fig. I 

 (dentition) ; Pfeiffer, Mon. Hel. vi. p. 158 ; Paetel, Cat. Conch. 1873, 

 p. 104; Schmeltz, Cat. Mus. Godeff. v. p. 91 ; Hartman, Cat. Partula, 

 p. 14 ; Obs. gen. Partula, Bull. Mus. Comp. Zool. ix. p. 183. 



This singular Partula lives on foliage near the sea-shore. I 

 obtained several hundred examples on Lanthala, and a few at Vanua, 

 Balavo, and Taviuni. Dr. Graffe found it on Kanathia and Oneata. 



It is, so far as known, the only species of Partula with elevated 

 spiral lirse. The type is pale cinereous, with the expanded lip and 

 aperture white. There is a depressed white tubercle on the parietal 

 wall. A tawny-brown variety is not uncommon. 



Genus Tornatelltna, Beck. 



J. TORNATELLINA OBLONGA. 



Tornatelltna oblonga. Pease, Proc. Zool. Soc. 1864, p. 673; 1871, 

 p. 473; Journ. de Conch. 1871, p. 93; Pfeiffer, Mon. Hel. vi. 

 p. 264 ; Schmeltz, Cat. Mus. Godeff. v. p. 89 ; Garrett, Proc. Phil. 

 Acad. Nat. Sci. 1879, p. 21 ; Journ, Phil. Acad. Nat. Sci. 1881, 

 p. 398, 1885, p. 81. 



Tornatellina bacillaris, Mousson, Journ. de Conch. 1871. p. 16, 

 pi. 3. fig. 5 ; Schmeltz, Cat. Mus. Godeff. v. pp. 89, 90; Pfeiffer, 

 Mon. Hel. viii. p. 316. 



Inhabits all the groups from the Marquesas and Paumotus to the 

 Viti Islands. On the ground in forests from near the sea-shore to 

 2000 feet above sea-level. 



Its slender form, imperforate base, and nearly vertical simple 

 columella will distinguish it. 



2. Tornatellina conica. 



Tornatellina conica, Mousson, Journ. de Conch. 1869, p. 342, 

 pi. 14. fig. 8 ; (var. impressa), p. 16 ; Pease, Proc. Zool. !Soc. 1871, 

 p. 473 ; Pfeiffer, Mon. Hel. viii. p. 316 ; Garrett, Proc. Phil. Acad. 

 Nat. Sci. 1879, p. 21 ; Journ. Phil. Acad. Nat. Sci. 1881, p. 399, 

 1885, p. 81 ; Schmeltz, Cat. Mus. Godeff. v. p. 89. 



Cionella conica, Paetel, Cat. Conch. 1873, p. 106. 



It has the same range as the preceding species, and inhabits the 

 same station. 



It is more robust and lighter-coloured than T. oblonga, the spire 

 more tapering, body-whorl larger, more compressed, parietal lamina 

 more prominent, and the columella more twisted than in that species.
