This species is closely related to the next one, and some care is required to distinguish 
the two at first. The longer antennules, and the armature of the second joint of the endopodite 
of 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.

This species was well distributed over the area investigated by the ‘Siboga’, as shewn 
by the records of the stations where it was noted.
