198 COCK.ERELL AND COLL1XGE : CHECK-LIST OF SLUGS. 



44b. Var. umbrosus, Phil. This name may be taken to represent 

 a slight mutation like maculatus, Kal., but with the dark 

 colouring more brown. 

 44 q. Yar. lineolatus. Mr. Collinge must forgive me for saying that 

 I am still quite puzzled about this form, owing to the 

 yellowish tentacles. "Will not its author give some further 

 details about it ? 8 

 44 r. canariensis. This probably does not differ from the type. 

 Z. canariensis of Mr. E. A. Smith (P. Z. S„ 1849, pp. 276-78) 

 is another thing altogether, being Agriolimax agrestis, v. 

 sylvaticus, Moq., as I have satisfied myself by an examina- 

 tion of the original specimens. Dr. Simroth in his 

 beautiful work on the slugs of Portugal and the Azores, lias 

 drawn some erroneous conclusions from the misidentifica- 

 tion of canariensis. 



44. Z. ehrenbergi. Heynemann states that this is flavus. It was 

 supposed to have no shell. 



44. L. megalodontes, Q. and G. Found near Port Jackson, 

 Australia. The Australian malacologists seem agreed that 

 this is flavus. 



57. Heynemann remarks of phozniciacus that Bottger thought it 

 was Agriolimax agrestis, but from the figure it might be 

 variegatus (flavus). 



59. Z. lineolatus. The description reads like the young of a dark 

 form of flavus. 



65. Z. cobanensis. Probably an Agriolimax. 



68. Z. lalus. Fossil in the I. of Wight. Z. modioliformis is also 

 English. 

 71-77. Eumilax, having priority over Paralimax, must be used for 



the genus. 

 Amalia. — Aspidoporus is older than Amalia, and Clytropelta than 

 Lallanantia ; yet it would seem absurd to adopt these 

 names, both founded on fictitious characters. 

 7S b. typica, Poll. This is in the British Museum from Bath. It 

 is like hewstoni. 



79. A. plumbea may appear either as a variety or sub-species, 

 according to the locality ; that is to say, in England it 

 represents a geographical race or subspecies, but plumbeous 

 specimens may occur where the type prevails, just as black 



Mt seems foolish to puzzle one's self over such .1 very minor colour variation as yellow 

 tentacles. I have no further details to add to my original description. As its name indicates, it 

 had a line on the sides of its body, and as such a form was not known, I thought it of sufficient 

 importance to name. — W.E.C.
