NOTES ON THE TERRESTRIAL MOLLUSCAN 

 FAUNA OF NE\A^ CALEDONIA, 



By E. RUTHVEN SYKES, B.A., F.Z.S., 



Honovary Secretary of the Malacological Society. 



We have to congratulate Mons. Crosse on the recent publication"'' 

 of the first part of his excellent study on the fauna of New 

 Caledonia. This has induced the writer to put together the 

 following notes, the result of a study of that fauna made some 

 time ago, in conjunction with Mr. Ponsonby. The responsibility 

 for this publication, however, must rest with the writer. 



Speaking of Rhytida hanakina, Gassies, Mons. Crosse 



remarks (p. 185) " De plus, les conditions dans lesquelles s'est 



" effectuee la dispersion de ses collections neo-caledoniennes, 



" rendent absolument incertaine la resource de la consultation 



" du type," Any record, therefore, of these types of Gassies is 



of interest : the British Museum, at the sale of his collection, 



acquired a considerable portion of the shells from New Caledonia, 



and amongst them were the following Helicoid land-shells, most 



of which are type specimens : — 



Diplomphalus cabriti Cliaropa mclalciicarum 



Rhytida multisulcata ,, vetula 



,, luteal ilia ,, rusticitla 



,, lamberti ,, dispersa 



,, rufotincta ,, deer eta 



,, subnitens ,, confiiiis 



,, testiidinaria ,, inculta 



,, raynali ,, melitae 



Hyalinia subfidva ,, rhizophorarum 



,, savesi ,, subcoaeta 



Microcystis bourailmsis ,, opaoana 



Platyrhytida occlusa ,, koutoumensis 

 ,, bruniana Trochomorpha lalannei 

 ,, oriiinda 



There is also Rhytida viUandrei, erroneously described from 

 New Caledonia. The classification given above, is that of 

 Mons. Crosse : Gassies, as is well known, usually describing his 

 species as belonging to Helix or Zonites.
