606 ON CRUSTACEA BROUGHT BY DR WILLEY FROM THE SOUTH SEAS. 



In regard to the nomenclature adopted in this report, I am bound to direct the 

 attention of critics and censors to an innovation, by which the term Cumacea, just as it 

 was at length becoming familiar, is displaced in favour of a new title. Of minor import- 

 ance is the defence here put forward for the use of the generic name Cubaris in prefer- 

 ence to that of Armadillo among the terrestrial isopoda. 



The following list shows the species dealt with in the present report, with the 

 habitat from which each was obtained.
