A specimen of Ilyperia has been sent to us by Mr. Edward, 

 of Banff, that we take to be a vax-iety of this species: it differs 

 in having the antennae much less developed than those in 

 the typical specimens. It looks like a young H. Galha, with 

 rudimentary antennae, 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 fovmd it on the shores of the 

 Moray Frith in December, January, and February, that is, 

 at a time when the Medusae are not on the coast.
