22 ANNALS OF SCOTTISH NATURAL HISTORY 



paratively recent time connected with the Outer Hebrides, 

 from which it is now separated by a somewhat shallow 

 stretch of sea. Some interest therefore attaches to the 

 comparison of the present list, with one 1 made a little 

 previously at Balelone, N. Uist, in a locality directly opposite 

 St. Kilda. This is the nearest point (36 miles) to the more 

 outlying island, which it resembles in general conditions. 



Numbers indicate the occurrence of the species during 

 the month, June 10 to July 10. 



ARION ATER, L. Occurs everywhere in profusion. On the hillsides 

 and in drier situations generally the type was dominant ; else- 

 where, especially in marshy spots, several lighter forms occurred. 

 Vars. brunnea (common) and marginata occurred. Nearly 

 mature whitish and yellowish examples were not infrequent, but 

 in all the darker tinge had begun to appear dorsally. These 

 were probably forms of vars. albolateralis and bicolor or sub-var. 

 Scharfii. 



ARION SUBFUSCUS, Drap. --(2). One perfectly adult, moist ledge 

 at back of Connacher. Again, 8/7/'o5, near village. 



ARION HORTENSIS, Fer. Common in damp situations and under 

 cow droppings. 



ARION INTERMEDIUS, Normand. Fairly common, varying greatly in 

 size. Like the preceding species it favoured the under surface 

 of cow droppings, doubtless on account of the fungoid growths 

 there. 



AGRIOLIMAX AGRESTIS, L. Generally common. 



AGRIOLIMAX L^EVIS, Milll. Seen frequently at foot of Mullachs 

 Mhor and Connacher during early part of the month ; not again 



till 8/ 7 /'o 5 . 



LIMAX ARBORUM, B. Ch. The slug of St. Kilda. Swarms in all 

 situations from sea level to the highest rocks. After heavy 

 rain in countless numbers on every wall in the village. Frequents 

 the sheer cliff faces down almost to the nesting ledges of the 

 Guillemot. 



Var. nigra. (2). Back of Connacher; mouth of Avon 

 Mhor. 



VITRINA PELLUCIDA, Miill. After much searching dead mature 

 shells were discovered on narrow ledge down the cliff face on 

 N.W. Very immature living examples also occurred here : 

 adult never seen alive.
