PALUDOMUS. 45 



" This is an ally of P. stephanus, Benson, so far as form is con- 

 cerned, but it differs widely in sculpture, and although that is not 

 a, character of much importance in the genus Paludomus and its 

 allies, still, as no intermediate forms between the two are known, 

 it appears quite justifiable to separate them.' 7
