120 LAND- AND FRESHWATER MOLLUSKS 



NOTE III. 



ON A COLLECTION OF LAND- AND FRESHWATER 

 MOLLUSKS FROM TALIABÜ (XULLA-ISLES) 



M. M. SCHEPMAN. 



(With Plate 1). 



The Mollusks recorded in this paper, have been collected 

 by Mr. J. W. van Nouhuys on Taliabu, one of the larger 

 Xulla-isles, and vs^ere presented by him to the Leyden Mu- 

 seum of Natural History, together with a few other species 

 from various localities, amongst which latter are however 

 no new species. As the only record of Mollusks from the 

 Xulla-isles is that of Xesta citrina var. by Wallace, men- 

 tioned hereafter in my note on X. halmaherica, I thought 

 it would be interesting to enumerate them all, instead of 

 describing only the new forms. I think the number of species 

 existing in that island will not be exhausted by these 17 

 species, the more so as the second part of the collection 

 contained several species not represented in the first lot, 

 but the number seems to be important for a locality the 

 molluscan fauna of which was nearly quite unknown.

The collection contains a large number of a Xesta, which 

 agrees in many respects with the figures of Kobelt, though
