COCKERELL AND COLLINGE : CHECK-LIST OF SLUGS. 



i2o/. xanthosoma. This is stated to be yellowish-amber, so it might 

 be identified with rufescens, D. & M. There is a more 

 extreme form, bright orange above, of which Mr. Wilcock 

 sent me a drawing, with the following description : — 



" Body and mantle bright orange red, shading to greyish 

 down the sides ; tentacles and head fuscous." This might 

 better be referred to siuriiieiis, of which Westerlund writes 

 '■'■supra siibnifus, siibtus a/bus.'" It was found in Yorkshire. 



\20 r. bilobatus. A curious malformation ; the only specimen I have 

 seen came from Philadelphia, U.S.A., sent by Mr. Pilsbry, 



12 1. virescens, if the same, takes priority. 



123. Liniax setcliuanetisis is evidently an Agriolimax ; the figure 



looks like agrestis. 

 131. A. simrothi. This name is proposed for the species indicated 



by Simroth in his work on the slugs of Portugal and the 



Azores as drynionius, Bgt., the true drymonius being an 



Amalia. 

 148. A. hanryaiiiis. May not this be a form oi agrestis. 

 \K^o. pallens ; see Fort. -Azor. -Faun., p. 313. Is it a slip for 



pallidus ? 



152. A. nitidus. According to Simroth, Bourguignat's ^/w/^t7/Vj'/'///j' 

 is a species similar to nitidus, but Polionera thinks 

 differently. 



154. A. tncntonicus. Tryon refers this to agrestis, but it seems 

 rather to be some form of /(^vis, or allied thereto. 

 1 58-1 7c. Simroth is disposed to refer all these to /eeris, but never- 

 theless they show some distinctions among themselves. 

 Certainly when one examines many specimens it becomes 

 exceedingly difficult to draw specific lines ; and from any 

 point of view, no doubt to have six names for the Central 

 American forms, and three for those of South America, is 

 quite unnecessary. In North America there were three 

 nominal species in the books for some time, but as soon as 

 they could be sufficiently compared, it w'as seen that they 

 were at best only varietally distinct. A more recently 

 discovered species from the Pacific coast of Ni)rth America 

 {heniphilli) seems adequately distinct from canipestris, but 

 is, in my opinion, a variety of A. berendti of Central 

 America. 



158. A. rarotongafius. In the British Museum are specimens from 

 Rarotonga (coll. Rev. Wyatt Gill ; pres. by Sir J. Lubbock)
