NON-MARINE MOLLUSCS OF SURINAM. 1 
NOTE I. 
THE NON-MARINE MOLLUSCS OF SURINAM. 
BY 
Dr. J. H. VERNHOUT. 
(With a sketch of Surinam and Plates 1 and 2). 
Whilst the Molluse-fauna of the Dutch colonies in the 
eastern hemisphere has been studied since very remote 
times, and its literature represents a considerable pile of 
very valuable papers, written by well-known conchologists 
and investigators of many parts of the world, the Dutch 
West-Indies, and especially Dutch Guyana or Surinam, 
are very little known in regard to their molluscs. As far as 
I know the only existing list of non-marine molluscs of 
Surinam is that given by the late Prof. Ed. von Martens 
in his „Binnenmollusken Venezuela’s”. That list excepted, 
it is only by chance that one finds the habitat ,Surinam” 
in a malacological paper: either in a note on newly acquired 
collections of shells, or in monographs of some families, 
or in books of travels. The few references about molluscs 
from Surinam I happened to find in literature, are to be 
found at the end of this paper. I hope my fellow-concho- 
logists will kindly inform me when any note on molluscs, 
collected in Surinam, is coming to their notice. I should 
not wonder if, besides the few mentioned in literature, 
still more specimens from Surinam are existing in some 
museum-collections.
