Amalia carinata , form nigrescens (Roeb.). 
Amalia marginata , var. nigrescens, Roebuck, MS., Ckll., Nat. World, 
Sept. 1886, p. 179. 
Dark grey or nearly black, without an internal shell. 
Middlesex and Surrey. 
This is an extreme dark form, and, curiously enough, 
though several specimens have been carefully dissected by 
two or three conchologists, no shell has been found present. 
Limax Ehrenbergij Bourg., a form of L. favus, is similarly 
said to have no shell. 
Amalia fulva (Paulucci). 
Amalia carinata, Leach, subspecies. 
Limax carinatus, Risso, 1826. 
Milax carinatus, Locard, Cat. Gen. Moll. France, 1882. 
The southern form of carinata , known as carinata , Risso, 
has been considered a distinct species from that of Leach by 
Locard and others ; but it appears to be only a subspecies at 
best. Risso’s name is later than Leach’s, so it cannot be 
used according to the law of priority. A. argillaceus y Gass., 
1856, has been quoted under carinata , Risso, but it is really 
a synonym of carinata , Leach. 
A. marginata , var. fulva , Paulucci, 1879, belongs to the 
southern slug, being the young or a slight variety, and I have 
adopted this as the earliest available name for the subspecies.
