LAND- AND FRESHWATER SHELLS 



COLLECTED BY D^ H. TEN KATE IN SOEMBA, TIMOR 



AND OTHER EAST-INDIAN ISLANDS 



DESCRIBED BT 



M. M. SCHEPMAN. 



(Plate 6). 



The shells collected by Dr. ten Kate, are from localities 

 which were still very imperfectly or not at all explored. 

 To the latter category belongs the isle of Soemba , which 

 has furnished a few very fine and interesting new species. 

 Other species, though known to science, are remarkable 

 for the novelty of their localities or because the habitat 

 was not yet ascertained. 



Considering that Dr. ten Kate travelled in behalf of the 

 Dutch Geographical Society and that his chief occupations 

 consisted of geographical and ethnological investigations, 

 the number of species presented to the Leyden Museum 

 must be called important. With respect to the literature , 

 I must remark , that I have usually cited : for the Land- 

 shells, the second volume of the Zoological Series of »Die 

 preussische Expedition nach Ost-Asien" , by Prof. Ed. von 

 Martens , Berlin, 1867, and for the Melanidae and Neritinae , 

 the monographs of these genera published by Dr. Brot 

 and by Prof, von Martens in the second edition of Martini 

 Chemnitz' »Systematisches Conchylien-Cabinet"; these works 

 give a full account of the synonyms.
