1898.] ScHARFi^. — The La7id Molhisca of the Great Skcllig. 11 



ZONITID^. 



Hyalinia ccllaria— (Standen). 



H. nitidula— (vStanden). 



H. alliaria* — (Standen, Welch, Cockerell). — It is significant that this, 

 the most sylvan of all the British Hyalinui:, should be the only 

 common species of the genus living on the island. All the specimens 

 I received from Mr. Delap and also those recorded by Messrs. Welch 

 and Standen belong to the greenish form (f viriduld), but Mr. 

 Cockerell mentions having among many specimens seen a few pale 

 brown ones. None of the specimens I examined had a trace of the 

 usual garlic smell. 



ARIONID^. 



Arion atcr* — Olive and black varieties. 



A. subfuscus— (Standen). 



A. intermedius* (wwm^i-)— Orange-yellow variety. 



LIMACIDi^E. 



Li max marginatus* {arbonmi) — 



a. Uniformly grey without bands ; 



b. Ivight gre)' with thick black bands on body and mantle. 



HELICID^. 



Helix rotundata* (Cockerell, Welch, Standen)— Small, otherwise 

 identical with continental specimens. 



H. ericctorum* — Immature. 



H. acuta* — Immature. 



H. ncmorans* (Cockerell, Welch, Standen). All conical in shape and 

 mostly much weathered. Among twenty-eight specimens I received, 

 there were twenty-seven of a lemon yellow colour {Jibclluld), and one 

 of a brownish red (without bands). Five of the twenty-seven yellow 

 ones were without bands, the remainder containing the following 

 band formulae : — 



15 specimens, 12345. i specimen, i (23) 45.

2 „ (12)3(45)- 2 „ (123) (45). 

 Cochlicopa lubrica— (Welch, Standen). 



Pupa cy II ndracca'— (Cockerell, Welch, Standen), — Mr. Cockerell 

 describes his specimens as pale and almost edentulate, whilst Mr. 

 Standen refers the Skellig form to the variet}- ciwta, but it seems 

 to me to be identical with the variety ancotwstoma, of which we 

 possess specimens in the Dublin Museum from St. Helena and 

 Triest, and which also occurs in the Canary Islands, the Azores, and 

 in Southern Europe, generally. 

 * The species marked with an asterisk are those of which I have 



myself seen and identified specimens.
