200 Mr. E. A. Smith on the Land- and 
additional species, nine collected by Mr. Thomson and the 
rest by MacGillivray. 
In the following list a few species * recorded from Wood- 
lark Island are omitted, as that island scarcely comes within 
the Louisiade group, being situated considerably to the north. 
A. TERRESTRIAL SPECIES. 
1. Nanina divisa, Forbes. 
Helix divisa, Forbes, Appendix to MacGillivray’s Voyage of the 
‘ Rattlesnake,’ vol. ii. p. 376, pl. ii. figs. 5 a-b; Reeve, Conch. Icon. 
fig. 1450; Tryon, Man. Conch. ser. 2, vol. ii. pl. xiii. fig. 70. 
Hab. Sudest Island. 
2. Nanina inclinata, Pfr. (Pl. XIII. fig. 16.) 
Helix inclinata, Pfeiffer, Proc. Zool. Soc. 1863, p. 526; Monogr. Hel. 
vol. v. p. 129. 
Hab. Louisiade group (New Caledonia). This is evidently 
a lapsus calam?, New Guinea of course being intended. 
A number of specimens from St. Aignan obtained by 
Mr. Thomson agree in many respects with the description of 
this species, but exhibit on the upper surface excessively fine 
spiral strie, which are not mentioned but may have been over- 
looked by Pfeiffer. N. divisa is rather smaller, less acutely 
keeled, and has the perforation a little more open. 
3. Nanina rosseliana. (Pl. XLII. fig. 15.) 
Testa anguste perforata, depresse conoidea, in medio acute carinata, 
roseo-fuscescens, superne subnitida, infra valde polita: anfract. 6, 
planiusculi, lente crescentes, lineis incrementi obliquis arcuatis, 
striisque spiralibus confertis minutis sculpti ; ultimus haud descen- 
dens, supra et infra carinam impressus, inferne haud spiraliter 
striatus ; apertura angulato-lunata ; perist. simplex, tenue, supra 
umbilicum leviter expansum et reflexum. 
Diam. maj. 40, min. 36, alt. 213 millim, 
Hab. Rossel island. 
This species is larger than either N. divisa or N. tnclinata. 
It is of a brighter vinous brown colour and has a rather more 
conical spire. 
4. Trochomorpha nigrans. (Pl. XIII. figs. 9-11.) 
Testa late umbilicata, depresse conoidea, castanea, linea filiformi 
* Helix woodlarkiana, Souverbie, Partula similaris and P. woodlark- 
tana of Hartmann, Pupina moulinsiana, Fisch. & Bern., &e.
