* Manzoni's fig. 1, plate ii. (' Supplement ') is not referable to this species, 

 but probably to the F. coronata, Audouin (=F. umbracula, id.), which may 

 be identical with Heller's L. appendiculata, and perhaps even with Busk's 

 L. marsupiata, a Madeiran species. All these forms are certainly most 

 closely allied.
