38 G. O. SAKS. PRELIMINAKY NOTICES ON THE SCHIZOPODA. 



Hab. Off Christmas Harbour Kerguelen. 120 fms. Several 

 specimens. Antarctic ocean (Stat. 153), 1675 fms. 1 single rather 

 large but imperfect specimen. 



Remarks. This species is very nearly allied to P. roseum from 

 the Norwegian coast, but may be known by the somewhat different 

 form of the antennal scale and of the telson, the armature of which 

 also exhibits some difference.
