140 GASTROCOPTA, EAST INDIES, POLYNESIA. 



lip a little expanded throughout, and slightly thickened, sin- 

 uous outwardly below the suture, bidentate deep within, the 

 upper tooth smaller, at the base having a single minute tooth, 

 and in the middle of the columella another stronger one ; 

 labium thin, adnate, provided with a bipartite, lamelliform 

 tooth above the middle, near the posterior angle. Length 2.15, 

 diani. 1, length of aperture 0.8, width 0.6 mm. (8tol.).

i ' This is of exactly the same type as the Arrakanese P. filosa, 

 described at p. 333 of the Journal for last year, but it is 

 larger, more cylindrical, and has one tooth more in the aper- 

 ture. From P. avanica it differs by less closely wound whorls, 

 and by the internal dentition of the aperture. It appears to 

 be a very rare species. I found one specimen under the bark 

 of a cocoanut tree on Penang, and two others 011 the opposite 

 coast, in the Wellesley Province" (Stoliczka) . 



I have not seen this species, which has been referred by von 

 Moelleudorff to Boijsidia (Proc. Zool. Soc. Loud., 1891, 337), 

 but he had not seen specimens. P. filosa, which Stoliczka com- 

 pares, certainly belongs to the Ncsopupa group. Before see- 

 ing specimens of filosa I had copied the figures on pi. 25, figs. 

 10, 11. 



VII. SPECIES OF THE PHILIPPINES, EAST INDIES, MICRONESIA, 

 MELANESIA, POLYNESIA AND HAWAII. 



The subgeneric positions of G. capillacea, G. microsoma and 

 G. neocaledonica are uncertain. G. lijonsiana belongs to the 

 typical group of Gastrocopta. All of the rest belong to the 

 subgenus Sinalbimdo, and, with the exception of G. moetten- 

 dorffiana, their affinities are with Australian species. 



Adaptability to life around habitations has, no doubt, led to 

 the vast Polynesian distribution of G. pedicidus. I infer that 

 it has been carried from island to island, sticking to native 

 impedimenta, cocoanuts, or other food materials, in the thou- 

 sand years or more of inter-island canoe voyages of the Poly-
