Arion flavus deposits its eggs from September to De- 

 cember. They are oval and yellowish. 



Not uncommon amongst damp dead leaves and the 

 fungus Nidularia striata at Highfield House ; on Oxton 

 bogs, on the rhizoma of the fern aspidium theli/pteris ; 

 at the roots of Lastroea cristata and at the base of the 

 hog-mosa (Sphagnum obtusi/olium); at Wollaton rare 

 amongst the Jichen (Peltidea canina) in shady damp 

 woods. Elsewhere, Newcastle (rare. Alder) 



We have therefore every representation of British 

 Arions. 



A single Irish species, Geomalacus maculosus, 

 separates the Arion tribe from that of the Limax 

 family. As yet the discovery of this slug has been 

 confined to the county of Kerry.

The animals of the Limax family very closely re 

 semble the form of the Arion, being somen hat oblong: 

 they do not, however, possess the gland on the ex-

The Limax occasionally suspend themselves, like the
