OX THE LAND-SHELLS OF CUEACOA AND THE NEIGHBOURING 



ISLANDS. 



By Edgar A. Smith, F.Z.S., etc. 



Read lOth Jime, 1898. 



Some years ago Dr. Ernst Hartert, whilst travelling in the West 

 Indies, paid a short visit to Cura^oa and the neighbouring islands 

 of Oruba and Buen Ayre, or Bonaire, and although occupied chiefly 

 in bird-collecting, he also obtained a small collection of land and 

 fresh- water shells, which have been very kindly submitted to me for 

 identification. 



The land-shells of those islands are very few in number, and 

 with the exception of Hiilimulus elongatus, are restricted in their 

 distribution. 



Six species are known from Cura^oa, viz. : 



1. BuUmulus elongatus. 



2. Cerion uva. 



3. CyUndrella Raveni. 



4. Pupa longiirio. 



5. Cistula Raveni. 



6. Tudor a megacheila. 



In Bonaire the following occur : 



1. Pineria Bonairensis, n.sp. 



2. CyUndrella Raveni. 



3. Neosiibulina Harterti, n. gen. et sp. 



4. Tudora aurantiaca. 



In Oruba there are found : 



1. BuUmulus elongatus. 



2. Cerion uva. 



"Whilst at Los Eoques we have : 

 1. Ravenia Blandi. 



1^0 fresh-water shells have hitherto been recorded from any of these 

 islands. The two found by Dr. Hartert are Paludestrina crystallina, 

 Pfr., from Buen Ayre, and a Planorhis from Cura9oa. Three rather 

 young specimens of the latter do not offer any special characters, and 

 at present must remain undetermined.
