230 ENiD^. 



None of the Indian species appears to have had its anatomy 

 investigated and their reference to these three subgenera is, there- 

 fore, based purely on conchological grounds. 



It is somewhat surprising to find that many continental 

 raalacologists continue to use the name Btdimimis for the genus 

 in spite of the fact that as far back as 1903 Mr. B. B. Woodward 

 had pointed out * that this name is preoccupied and that Una 

 must be adopted in its stead. The only exception to this, to 

 my knowledge, appears to be l)r. J. Thiele. Kobelt in 1900 

 and Mollendorff in 1902, indeed, have already used the name Ena 

 but only in its restricted sense, i. e. for the group of montanus 

 for which in 1850 Albers proposed Merdigerus.
