A New Variety of Arion ater. — I have had a rich collection of slugs from 

 Church Stretlon, in Shropshire, collected ]6thSept., 1918, by Mr. G. B. C. Leman. 

 It included Umax iiiaxiiiius vars. concolor, fasciata, and cella7-ia, Limax arborum, 

 Milax sowerbyi, Af. gdgates, Agrioliniax agi estis var. reticulata, Arion drcuin- 

 scrifitiis, A. intermedius, type and var. grisea, A. subfiiscus vars. rufofiisca and 

 fnliginea, and A. ater, type and vars. castanea, nigrescens, castanea -\- fasciata, 

 and a couple of adult specimens of a variety which I have never seen before. It is 

 of the bicolor and albolateralis group, having the colour of the back sharply and 

 definitely separated from that of the sides, but is not referable to either of these 

 varieties. In the interest of precision I venture to characterize it as new, thus : — 

 " Arion ater var. salniolateralis nov. — Back black, _sides pale warm orange in 

 colour, the colours sharply separated from each other." In this example, one of the 

 most brilliantly coloured examples I have ever seen of the species, the foot-fringe 

 is brilliant orange. I have sent the type specimen to the British Museum for per- 

 manent preservation. — -W. Denison Kok^xsck {Read befoie the Society, Oct. 12th,
