2. Trochomorpha abrochroa, Crosse. 



Helix abrochroa, Crosse, Journ. de Conch. 1868, p. 176; 1870, 

 p. 101, pi. 1. fig. 2; Pfeirter, Mon. Ilel. vii. p. 207. 



Trochomorpha (Discus) abrochroa, Mousson, Journ. de Conch. 

 1870, p. 123, v&r. pseudoplanorbis. 



This species, which appears to be somewhat scarce, was found by 

 me under dead wood in the mountain-forests on Kioa Island. Dr. 

 Graffe obtained it on Viti Levu. 



Easily distinguished by its thin texture, uniform luteous horn- 

 colour, depressed form, sharp crowded striae, and the angle on the 

 margin of the wide umbilicus. Diam. 12 millim. 



3. Trochomorpha ludersi. 



Helix luflersi, Pfeiffer, Proc. Zool. Soc. 1855, p. 112; (Videna) 

 Vers, p. 132 ; Mon. Heh iv. p. 183. 



Trochomorpha (Discus) ludersi, Mousson, Journ. de Conch. 

 1870, p. 122 (part.). 



This fine species is abundant on the trunks of trees at Gnau 

 (Angau) Island. I received a few specimens from a native at 

 Ovalau, where Macgillivray obtained the type examples. 



Its large size (19 millim.), light horn-colour, and, more particularly, 

 the four narrow reddish-brown bands, two above and two in the 

 base, will separate it from any other Vitian species. 



4. Trochomorpha taviuniensis. 



Helix taviuniensis, Garrett, Amer. Journ. Conch. 1872, p. 22 3 

 (" Tavinniensis " typ. err.) ; Schmeltz, Cat. Mus. GodeiF. v. p. 95 ; 

 Pfeiflfer, Mon. Hel.'vii. p. 574. 



Found in numbers on the trunks of trees in damp forests on 

 Taviuni. 



A little smaller and more depressed than T. ludersi, with a single 

 narrow chestnut-brown submarginal band, both above and beneath, 

 on a tawny-yellow ground. Out of over 300 specimens one only 

 was without the bands, and was more depressed and paler than the 

 type. The bands are darker and wider than in the preceding 

 species. 



5. Trochomorpha tumulxjs. 



Helix timidus, Gould, Proc. Bost. Soc. Nat. Hist. 1846, p. 1 75 ; 

 Expl. Exp., Shells, p. 62, fig. 53 ; Pfeiifer, Mon. Hel. i. p. 85 ; 

 Mousson, Journ. de Conch. 1865, p. 194, 1870, p. 120; Schmeltz, 

 Cat. Mus. Godeff. v. p. 94. 



Nanina tumulus, Gx?iy,C&t.V\x\m. -p. 128; (Trochomorpha) Mhtrs, 

 Die Hel. 2nd ed. p. 60 ; (Discus) Paetel, Cat. Conch, p. 85. 



This species, which is unknown to me, inhabits Viti Levu. 

 Schmeltz cites Samoa as one of its habitats, which is probably a 

 mistake, as Prof. Mousson does not mention it in his paper on the 

 Samoan land-shells. 



It is described as a small (14 millim.), solid, yellowish, pyramidal
