ADDITIONAL NOTES ON THE NON-MARINE MOL.LUSCA 

 OF MORTEHOE. 



By M. jane LONGSTAFF, F.L.S, 



(Read before the Society, January 12, 1910). 



The mollusca here enumerated were collected between May 28th and 

 June ist, and between July 19th and September 23rd, 1909. Tl>^e 

 which are new to Mortehoe parish — as previously defined— are dis- 

 tinguished by an astei-isk. Fresh localities for a few ofj the rarer 

 species occurring either in this district or in the immediate neigh- 

 bourhood are also recorded. The additions now made bring up the 

 total for the parish to fifty-two species and forty varieties. ,- 



I must acknowledge my gratitude to Messrs. B. B,. Woodward, 

 J. W. Taylor and W. Denison Roebuck for their kindness in deter- 

 mining or confirming the names of species and varieties. 



*Limax cinereo-niger Wolf. — Borough Wood. Young specimen 

 of the type form. Identified by W.D.R. 



*Agriolimax laevis (Miill.). — Pool Farm, under a stone at the 

 edge of a ditch. Confirmed by W.D.R. [Two at the edge of a pond 

 at Croyde].

 numerous under stones in company with Af. soiverbii (Fer.). Con- . 

 firmed by W.D.R. 



Vitrea radiatula (Alder). — Borough Wood, one living specimen 

 among dead leaves ; Woolacombe, one dead, very large. Though 

 Mr. Tomlin states this species to be common on Lundy, I have so 

 far found it scarce in the Mortehoe district, and therefore think,: it 



well to record new localities for it. . _ 



Vitrea pura (Alder). — Borough Wood, four additional specinxeiis 

 taken here ; Kitty Nest Cleeve, abundant on dead leaves. 



*Euconulus fulvus (Miill.). — Kitty Nest Cleeve, eleven examples, 

 on dead leaves; Borough Wood, one living specimen among dead' 

 leaves. 



*Punctum pygmaeum (Drap.). — Kitty Nest Cleeve, eleven 

 specimens among dead leaves. Confirmed by J.W.T.
