 paris carpo paullo longius. Rami pedum uri marginibus fimbriatis; ramus externus jiedum 

 primi paris internum longitudinu ajquans ; ramus externus pedum secundi paris interno bre- 

 vior. Tehon quartam partem pedunculi pedum uri ultimi paris longitudine sequans. 



The head is sliorter than tlie first three perasonal segments together, and is much deeper 

 tlian long. The perceon is not inflated; the last two segments are not produced dorsally(?). 

 The second pair of piermopioda ai'e a little longer than the first, and reach almost to the

As I have said above this s])ecies cotnes very riear to Phronimopsis Sarsi, and the 

 distinguishiiig- charactcristics are few, and of sinall iinportance, but as the characteristics 

 of the urus and its appendages suggest a distinction I have not united the species. 



I refer the reader to the description and drawings given by Stebbing.
