Amalia carinata^ form nigrescens (Roeb.). 



Amalia maryinata, var. niyrescens, Roebuck, MS., Ckll., Nat. World, 

 Sept. 188(5, p. 179. 



Dark grey or nearly black, without an internal shell. 



Middlesex and :Surrey. 



This is an extreme dark form, and, curiously enough, 

 thougli several specimens have been carefully dissected by 

 two or three conchologists, no shell has been found present. 

 Liviax Ehrenhercji, Bourg., a form of L. flavus^ is similarly 

 said to have no shell. 



Amalia fulva (Paulucci). 



Amalia carinata, Leach, subspecies. 



Liinax carinatus, Risso, 182G. 



Milax carinatus, Locarcl, 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. aryillaceuSj Gass., 

 1856, has been quoted under carinata, Risso, but it is really 

 a synonym of cai'inata, Leach. 



A. marcjinata, 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. 



Amalia fulva, form typus (Less. & Poll.). 

 Amalia fulva, ioxxo. ijallidissiina (Less. & Poll.).
