ROEBUCK : THE BRITISH SLUG LIST. 41 



Amalia gagates var. plumbea Moq. Animal black-grey, 

 more or less lead coloured (Moquin-Tandon). 



The specimens which Mr. C. Ashford has sent 

 me from Christchurch, S. Hants, where they are not 

 uncommon, were of this variety and were very con- 

 stant in their coloration. The Rev. B. J. Clarke in 

 1840 noted that the majority of his Irish examples — 

 found at La Bergerie in Queen's Co., Tuam in E. 

 Galway, and Tourmakady in E. Mayo — were also of 

 this variety. 



Limax maximus var. Ferrussaci Moq. Animal with 

 rounded black spots on the shield, and four rows of 

 black points on the body (Moquin and Pini). 



The Rev. B. J. Clarke in 1840 recorded speci- 

 mens taken in the churchyard at Monivea, co. Gal- 

 way, which closely resembled Ferussac's fig. 8, var. (, 

 beautifully and distinctly spotted, the ground colour 

 not so light as in Ferussac's figure. 



Limus maximus var. cinerea Moq. Animal ash-coloured, 

 without spots : shield bluish-black (Moquin-Tandon). 

 Found at Killereran, co. Galway — Rev. B. J. 

 Clarke, 1840. 



Limax cinereo-niger Wolf. 



This form has usually been treated by concholo- 

 gists as a variety of Z. maximus^ from which however 

 it is now separated by the best continental authorities. 

 It may be distinguished by the following external 

 characters : — the shield is unicolorous without mark- 

 ings or only with slight traces towards the edge ; the 

 respiratory orifice is margined with the colour of the 

 body, of a darker hue ; the dorsal keel is in colour 

 usually different from the general tint of the body ; 

 and the lower surface of the foot is divided longitudi-
