this island, written in Latin, contains ; — 1 Arioriy 4 LimaXy 2 Testacellay 4 Vi-

1864) 1 LimaXy 2 Vitrinay 30 Helix y 4 PupUy 1 PhysUy 1 Planorbisy 2 Cras- 
■pedopomay and 1 Pisidimriy beside the submarine genera which were not in- 
cluded by Albers. Most of these additions have been described within the 
last years by the author in Pfeifter’s ^Malokologische Blatter’ and Crosse’s 
^ Journal de Conchyliologie.’ 
Some remarks concerning the land-mollusks t)f this island are to be found 
in Von Mahtens’s zoological report of the Prussian Expedition. In the lower 
warm and dry region are found the types most peculiar to this island, as 
Helix undata, nitidmsculay and polymorpha ; in the upper moist and wooded 
region occur the European genera LimaXy Vitrinay Hyalinay Pupay and Clau- 
silia, together with the rather peculiar genus of CyclostomidcBy Craspedopoma. 
Stenogyra decollata has been found only near the town of Punch a!, and is pro- 
bably introduced from Europe. Freshwater shells are rare, Limnceus trim- 
caiidm and Ancylus aduncus have been found by the Kecorder, Planorhis 
glaben'—lcevis by Mr. Johnson. Auriculidce occur only near the sea, Pedipes 
afer even on rocks within reach of the waves, in company with Litorina.
