chaster: shell hunting in MERIONETHSHIRE. 79 



subject, as in certain respects, judging from the published 

 account, there is a similarity between the two places. Although 

 in the neighbourhood of the spot the mollusc was taken in the 

 habitat usually given, viz., 'among decayed leaves,' it was 

 only, as is usual, sparingly. Should I find, as I am inclined to 

 suspect, that Aciaila affects by preference another habitat, it will 

 be duly announced. 



Altogether 34 species of land and fresh water shells were 

 taken, viz. : — - 



Succinea putris Helix aibustorum 



* Vitrina pelhicida „ rufescens 

 Hyalinia cellaria „ hispida 



* ,, alliaria „ ftisca 



* „ glabra ,, rotundata and var. alba 

 „ nitidula * „ pygmcea 



* ,, piira and var. *Fipa ringeiis 



margaritacea */*. cyliiidracea and v. edentiila 



„ radiattila and var. * Vertigo substriata 

 viiidescenti-alba. ,, edeutula 



* „ nitida *Balea perversa 



„ excavata and var. Cochlicopa lubrica 



vitrina Caryclmim viinimum and var. 



* ,, cry stall ill a opaca 



„ fulva '''Acictda lineata var. alba 



* Helix lainellata Limniea peregia 



,, aadeata ,, tnincatida 



„ aspcisa * Pisidiuin pitsilhim 



,, nemoralis * ,, viilinm 



of which those marked with an asterisk have not been noticed 

 by me as recorded for the county. 



An afternoon was spent in shore hunting for marine 

 mollusca, but the results were disappointing. Almost every- 

 where the boulders were cemented together by the tubes of 

 Sabella alveolata, and under the few which were free only 

 Chiton marginatiis and two or three equally common things 

 were taken. Indeed the only marine shell worthy of mention 

 is Lepton darkice, which I had never before gathered.
