338 Rev. B. J. Clarke on Irish species of the genus Limax. 



were subject to more variety in their markings than I have else- 

 where seen them. 



* * Ma7itle rounded behind, marked with concentric stri(B ; end of tail 



keeled ; shell flat. 



1. Limax flavus, Draparnaud. (PL XI. figs. 11, 12.) 

 L. variegatus, Ferussac. 



L. " Lutescens, fusco maculatus, tentaculis caeruleis." — Drap. 



Hab. Cellars and damp ground-floors ; sometimes, but rarely, on 

 trees. 



This species may be easily distinguished by its azure-blue ten- 

 f'—tacles, the mantle being always mottled with yellow, the body 

 more or less covered with little oval yellowish spots, and the sides 

 pale yellowish. The yellow spots vary considerably in different 

 individuals, but the iigm-es which I have given represent the 

 usual forms which have occurred to me in Ireland. I have occa- 

 sionally observed this slug in the hollows of old trees, upon the 

 leaves of which it feeds. This species is not uncommon in Ire- 

 land, although nowhere plentiful. It is no doubt the slug which 

 Miss Ball alludes to as finding its way into pantries and eating 

 jTliDles in bread. I have supplied them with bread when kept in 

 £ confinement, and they eat it voraciously. 



* * * Mantle truncated behind, marked with concentric stria ; end of 



tail keeled ; shell flat, 



1. Limax agrestis, Linn. (PI. XII. f. 13.) 

 L. filans (young). Hoy. 

 Limacellus obhquus (shell), Turton. (PI. X. fig. 6?.) 



L. " Albidus maculatus et immaculatus, corpore subrugoso, aper- 

 tura lateral! postica." — Drap. 



Var. a. " Albidus, immaculatus." — Drap. 

 Var. /3. " Albidus, atomis nigris sparsis." — Drap. 

 Var. y. " Albidus, clypeo flavescenti." — Drap. 

 Hab. Fields and gardens : common. 



Of this abundant little species I have noticed all the varieties 

 described by Draparnaud. There is a curious dhli variety which 

 has occurred to me not unfrequently ; it is of a uniform dark pm 

 plish or slate colour, usually found in company with the otj 

 varieties. 



* * * * Mantle truncated behind, granulated or shagreened ; entir} 

 length of back keeled from the shield or mantle ; shell convex.
