384 Mr. T. D. A. Cockeiell's Notes on Slugs. 



Leach's type, marked ^^Limax carinaius, 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.). 



^erussac's Sowerhyi is simply a form of carinata, bright- 

 coloured and with strong markings. 



Amalia carinata, form hicolor (Ckll.). 



Amalia maryinata, var. bicolor, Ckll. Sci. Goss. Aug. 1887, p. 187. 



Sides black, keel and sole orange. 

 Ealing, Middlesex. 



Amalia carinata, form fuscocar in ata (Ckll.). 



Amalia murtjinata, var. fuscocarinata, Ckll. Nat. World, Sept. 188(i, 

 p. 179. 



JCeel coloured like the rest of the body. 

 Bedford Park, Middlesex. 



Amalia carinata, form rustica (Roeb.). 



Amalia marcjinata, var. mstica, lloeb. Sci. Goss. 1884, p. 78 ; Jouru. of 

 Concb. Oct. 1885, p. 303. 



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 followiug localities in England: — Couim. Docks, London, S.E. 

 {J. E. Dn?iiel) ; S. Shields (H. Howse) ; near London ( J. E. llartimj) ; 

 Bedford Park, Chiswick ( T. D. A. Cockerell) ; and a few others without 

 locality precisely given. One big specimen of A. carinata is marked "i. 

 carinatus and var. itallida (J. E. Daniel)." I cannot ascertain that any 

 var. pallida of the species has been described. The specimen from 

 Ecuador, presently to bo mentioned, was collected by ]Mr. Buckley, pur- 

 chased of E. Gerrard. It is 36 millim. long, mantle 12^ millim. long, 

 sole pale ochrej'^, 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 nirircsccns.
