Professor G. O. Sars considers (loe. cit.) that the genus 

 Delavalia is really identical with Stenlielia Boeck, but Boeck's 

 definition of Stenlielia assigns to the first pair of feet a 

 structure " similar to those of Dactylopus," and of this latter 

 genus he says of the first pair of feet that " the inner branch 

 is elongated, three-jointed, the first joint being very long and 

 bearing two prehensile bristles : the inner branch generally 

 smaller, with its middle joint not much longer than the other 

 two '' — both branches being therefore three-jointed. But one 

 of the most distinctive characters of Delavalia is the two- 

 jointed ^w^ non-prehensile \x\v\tx branch of the first foot. We 

 therefore prefer to retain that generic name. N.
