Mr. 1 . D. A. Cockerell’s Notes on Slugs. 
Leach’s type, marked “ Limax carinatus , given by R. 
Latham/' is still in the British Museum*; it is a rather large 
pale specimen. 
A. carinata is easily known from marginata by its dark 
sulcus .on the mantle and the usually dark-reticulated body. 
There is in the British Museum a specimen of A. carinata 
from Ecuador, collected by Mr. Buckley ,* doubtless it is an 
introduced species in that country. It is rather remarkable 
that the species has not yet been introduced into North 
America. 
Amalia carinata , form Sowerbyi (Fer.). 
Ferussac’s Sowerbyi is simply a form of carinata , bright- 
coloured and with strong markings. 
Amalia carinata , form bicolor (Ckll.). 
Amalia marginata , var. bicolor, Ckll. Sci. Goss. Aug. 1887, p. 187. 
Sides black, keel and sole orange. 
Ealing, Middlesex. 
Amalia carinata , form fuscocarinata (Ckll.). 
Amalia marginata , var. fuscocarinata , Ckll. Nat. World, Sept. 1880, 
p. 179. 
Keel coloured like the rest of the body. 
Bedford Park, Middlesex. 
Amalia carinata , form rustica (Roeb.). 
Amalia marginata , var. rustica, Roeb. Sci. Goss. 1884, p. 78 ; Journ. of 
Conch. Oct. 1885, p. 363. 
Colour grey, without any admixture of brown or yellow. 
This is apparently not rustica , Mill. 
* The British Museum also possesses specimens of Amalia carinata 
from the following localities in England: — Comm. Docks, London, S.E. 
(J. E. Daniel ) ; S. Shields (R. Howse) ; near London (J. E. Harting) ; 
Bedford Park, Chiswick (7\ D. A. Cockerell ) ; and a few others without 
locality precisely given. One big specimen of A. carinata is marked U L. 
carinatus and var. pallida (J. E. Daniel).” I cannot ascertain that any 
var. pallida of the species has been described. The specimen from 
Ecuador, presently to be mentioned, was collected by Mr. Buckley, pur- 
chased of E. Gerrard. It is 36 millim. long, mantle 12| millim. long, 
sole pale ochrey, median area twice as broad as either lateral area. It 
differs in nothing from those found near London. Among the Bedford 
Park lot is a specimen of form nigrescens.
