200 Mr. E. A. Smith on the Land- ayid 



additional species, nine collected by Mr, Thomson and the 

 rest bj 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, P'orbes, Appendix to MacGillivray's Voyage of the 

 ' Rattlesnake,' vol. ii. p. 876, pi. ii. figs. 5 a-b; Reeve, Conch. Icon, 

 fig. 1450 ; Tryon, Man. Conch, ser. 2, %-ol. ii. pi. xiii. fig. 70. 



Hah. Sudest Island. 



2. Nanina tnclindta, Pfr. (PI. XIII. fig. 16.) 



Ileli.r tnclinata, Vfeiffer, Proc. Zool. Soc. 1863, p. 526; Monogr. Hel. 

 vol. V. p. 129. 



Hab. Louisiade group (New Caledonia) . This is evidently 

 a lapsus calami, 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 striaj, 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. (PI. XiII. fig. 15.) 



Testa anguste perforata, depresse conoidea, in medio acute cariiiata, 

 roseo-fuscescens, superne subnitida, infra valde polita : anfract. 6, 

 planiusculi, lento crescentes, lineis increraenti obliquis arcuatis, 

 striisque spiralibus confortis miniitis sculpti ; iiltimus baud descen- 

 dens, supra et infra carinam impressus, inferne baud spiraliter 

 striatus ; apertura angulato-lunata ; perist. simplex, tenue, supra 

 umbilicum Icviter expansum et reflexum. 



Diam. maj. 40, min. 36, alt. 21 ^ millim. 



Hah. Rossel Island. 



This species is larger than either N. divisa or N. indinata. 

 It is of a brighter vinous brown colour and has a rather more 

 conical spire. 



4. Trochomorpha nigrans. (PI. XIII. figs. 9-11.) 



Testa late umbilicata, depresse conoidea, castanea, linea filiformi 



* Helix woodlarktana, Souverbie, Partula similaris and P. zvoodlark- 

 iana of Hartmann, Pupina motdinsiana, Fisch. & Bern., &c.
