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 Linnaeus' 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. 



T. LOBIANCOI Mazzarelli. Unfigured. 



Length (in alcohol) 27 cm. Green. Swimming-lobes free as far 

 as their union with the foot behind, as in leporina. Gill-cover
