Tethys limacina Linné, an absolutely unidentifiable species subse- 
quently referred to A. depilans by Linn.— Aplysia radiata CRoucn,

This is an abundant species, differing from depilans and punctata 
in the free backward extension of the dorsal lobes, and the minute 
foramen in the mantle leading to the shell-cavity, with the edges 
thickened, somewhat tubular. 
I have not seen the original edition of Poiret’s travels in which 
A. fasciata was first published, and therefore do not know its date. 
It was apparently after 1786, the last year of the voyage, and be- 
fore 1788, because Gmelin cites it in the Systema. The German 
translation is 1789. I adopt Linnzeus’ specific name because Ronde- 
let’s figure and description of the coloration agree well with this 
species, and not with any other European Sea Hare.

Length (in alcohol) 27 em. Green. Swimming-lobes free as far 
as their union with the foot behind, as in leporina.  Gill-cover
