A specimen of Hyperia has been sent to us by Mr. Edward, 
of Banff, that we take to be a variety of this species: it differs 
in having the antennze much less developed than those in 
the typical specimens. It looks like a young H. Galba, with 
rudimentary antenne, but one of the specimens sent to us 
has the incubatory pouch of the adult female fully developed, 
so that we cannot mistake it for a young animal. Mr. 
Edward says that he has never taken this species in a Medusa, 
and that he has frequently found it on the shores of the 
Moray Frith in December, January, and February, that is, 
at a time when the Medusee are not on the coast.
