This species is closely related to the next one, and some care is required to distinguish 

 the two at fust. The longer antennules, and the armature of the second joint of the endopodite 

 oi the fourth foot, are the specific points that separate the two species. The species recorded 

 from the Gulf of Guinea by my father as Paracalanus parvus (Claus), is probably Giesbrecht's 

 Paracalanus aculeatus.

 by the records of the stations where it was noted.
