The Iwo species of Pekilidiuin hilherlo named are still somewhat impei- 

 fcctly known. They difTer from one another ai least in Ihe branchial for- 

 mula and Ihe maie petasraa, probably besides in the rostrum and the clasp- 

 ing org-an of the antennuhe. The maie from 35" lat. S. menlioned and 

 parlly figured by lUig belongs decidedly to P. obesuin othervvisc laken only 

 in ihe North Atlantic, while P. foliacpinn Bâte is subaiitarctic , and the 

 feniale of which lUig figured the rostrum (his fig. 3i) belongs in ail pro- 

 bability to the last-named species.
