I02 MOEI.LENDORFF : LAND SHELLS OF CAROLINE ISLANDS. 



On the localities in which Kubary collected he wrote me the 

 following notes : In the North of the island are situated Mpom}:) and 

 MeitsiK; not far from the sea, and opposite to them the small island of 

 Djokoits. The soil consists of yellow clay which has been formed by 

 decomposed basalt, and is covered by dense bush. The ground 

 gradually rises to the chain of the hills in the interior. The soil in 

 the bush is covered by a thick layer of mouldering leaves in which the 

 Parhilae and bigger Trocliomorphae are very common. Trochomorpha 

 niijriteUa and its sub-species conti(jua were found on trees and shrubs, 

 the Pxqnnae and Helicinae partly in the mould and on Pandanus 

 and tree-ferns. 



Fam. NANINIDAE. 



1.— Lamppocystis palaensis (O. Scmp.). 



Mio-on/afis palai-nsi.-^, O. Semp. MS.; C Semper, Reisen Phil., 

 iii, p. 45, t. 2, f. i6. — Helix palacmis, Pfr., Mon. Hel., 

 vii, p. 94. — Xanina (Microcystis) palaensis, Tryon, Man. 

 Conch., ii, p. 120, t. 40, i. 37. 



Hall. — Pelew Islands (Semper), Yap (Kubary). 



An intermediate form between L. misella, Fer., of the Mariannes 

 and 2)seuilosuccinea, m., of the Philippine Islands. 



2.— Lamppocystis fpivola (Pse.). 



Helix frivola, Pease in Tryon, Amer. Journ. Conch., 1866, ii, p. 

 290, t. 21, f 3. — Pfr., Mon. Hel., vii, p. 72. — Hdicopsis 

 frivola, Pse., P.Z.S., 187 1, p. 4'j^.— Na7una (Micro- 

 cystis) frivola, Pfr., Nomencl., p. 37. — Tryon, Man. 

 Conch., ii, p. 118, t. 38, figs. 62 — 64. 

 Hah. — Ualan (Pease). 



Pfeiffer writes Owalao, Tryon Oualau, but I am sure Pease ob- 

 tained this species from Ualan or Kusaye, one of the Caroline Islands, 

 from whence he described other species. I do not think Ovalu of 

 the \\X.\ group was meant.

Kaliella tenuisnilpta, Mlldff, Jahresb. Senck. Nat. Ges., 1893, 



p. 69. 



Hah. — Ponape (Kubary). 



Most probably introduced from ^Manila, where it is common m 



gardens.
