100 MR. E. A. LIARDET ON FIJIAN LAND-SHELLS. [Jan. 18, 



and highly polished; whorls 5, convex; spire ohtuse ; suture im- 

 pressed ; aperture nearly vertical, roundly lunate ; columella short, 

 excavated, white, with a callous curved tooth near the base. 



Animal very active. I observed it on one occasion, when inter- 

 rupted in progression, lift its tail high, as in figure la, and shake it 

 vigorously. 



Hub. Islands of Taviuni and Gamia, Fiji. Rare. (Coll. Liardet.) 



2. Nanina? vitrinina, sp. nov. (Plate V. figs. 2, 2 a.) 



Shell yellow, thin, translucent, perforated, discoidal ; whorls 4|, 

 last subangulated, the others slightly convex ; beneath shining and 

 well rounded ; aperture slightly oblique, lunate ; suture marginate ; 

 peristome thin ; columellar lip slightly expanded over perforation. 

 Animal black, with mantle covering two thirds of the shell, which it 

 cannot enter at first. 



Found in moist situations under logs, in this respect resembling 

 Vitrina. (Coll. Liardet.) 



3. Nanina? ramsayi, sp. nov. (Plate V. fig. 3.) 



Shell similar to N. 1 vitrinina. When the animal is out I can 

 detect no difference. 



Animal red ; a protuberance on the back rests against the shell 

 anteriorlv. It progresses by raising its head, extending the body, 

 and placing the posterior part of the foot down in the form of an 

 arch, lands its body gradually from the head ; and this arch thus 

 appears to recede until the caudal extremity is reached. Like N. 1 

 vitrinina, it cannot at first recede into its shell ; and like Vitrina 

 strungei of Australia, it leaves mucus in its track of a brick-red 

 colour. 



Hub. Taviuni, Fiji. (Coll. Liardet.) 



4. Helix princei, sp. nov. (Plate V. figs. 4, 4 a.) 



Shell very small, depressed, with wide and perspective umbilicus ; 

 colour dark brown ; whorls 3, prominently costated ; suture deeply 

 impressed ; aperture round. 



Note. — This is the only Fijian shell I have seen resembling any 

 of the Australian Helices. 



Hub. Taviuni, Fiji. (Coll. Liardet.) 



5. Helix pinnocki, sp. nov. (Plate V. figs. 5, 5 a.) 



Shell conoid, perforate ; colour a horny yellow ; convex beneath ; 

 whorls 6", spirally striated, the last carinated, smooth beneath; aper- 

 ture oblique, roundly lunate ; columellar lip slightly expanded over 

 perforation. 



Hub. Taviuni, Fiji. (Coll. Liardet.) 



6. Helix barkasi, sp. nov. (Plate V. fig. 6.) 



Shell minute, trochiform, very minutely perforated, colour golden 

 horny; whorls 51, convex, roughly and irregularly striated, trans-
