Mr. T. D. A. Cockerell's Notes on Slugs. 283 



A. pp-7'ichus, Mab., is a form of marginata, and var. rufula^ 

 Moq.-Tand. (Moll, de France, pi. ii. %. 4), also belongs 

 here. 



A. rusticus, Mill., 1843, appears to be another form of 

 the same species as given by Moquin. L. carinatus of 

 Daniel, Heidelberg list (Quart Journ. Oonch. vol. i. p. 113), 

 may be true marginata^ and not Leach's species. Var. mon- 

 gianensiSj Paul., from Calabria (near Mongiana), is probably 

 referable also to marginata. 



Araalia marginata^ form pyrrichus (Mabille). 



Amalia marginata, form rufula (Moq.). 



Amalia marginata, form rustica (Mill.), 



Amalia margmata, var. ? mongianensis, Paulucci, 1879. 



Amalia Reuleauxi, Clessin, 1887. 



Amalia Reuleauxi, form punctata, Cless. 



I have not seen a sufficient description of Reuleauxi, but 

 it seems allied to marginata.

The above (excepting the second and the last two) are 

 references to British figures of this species, all representing 

 Leach's species, and not Draparnaud's marginata. The slug- 

 has been elsewhere described by several authors, but the 

 bibliography here given will suffice for present requirements. 

 The older authors correctly referred it to carinata, but the 

 reference to marginata, " Miiller " or " Drap.," has been 

 universal in England of late years, and needs correcting. 

 Limax marginatus, Miiller, is not even an Amalia.
