ADDITIONS TO THE LIST OF LAND AND FRESH- 

 WATER MOLLUSCA OF LLANDUDNO. 

 By J. R. BROCKTON TOMLIN. 



Having paid two visits to Llandudno during the last six 

 months, it will be of interest to supplement Mr. Roebuck's 

 article in the J.C., vol. iv., no. 7 (July, 1884). I have seven 

 new species to add to the list. 

 Limnaea truncatula. — Ditch on the Morfa and pond in 



Happy Valley. 

 Zonites fulvus. — One specimen in Gloddaeth woods. 

 Z. cellarius var. albida. — One specimen with H. aculeata. 

 Helix aculeata. — Ten specimens in moss on the Great Orme, 



a little above the Happy Valley, with Carychium minimum 



and Z. crystallinus. 

 H. ericetorum. — Plentiful but local in various parts of the 



Morfa, with var. alba. 

 H. ericetorum var. alba.— With type. 

 H. nemoralis var. roseolabiata. — Three specimens on 



the Morfa. 

 H. nemoralis var. hyalozonata. — Three specimens on 



the Morfa. 

 Vitrina pellucida. — A few on Great Orme ; plentiful under 



stones in one part of the Morfa, alive and dead. 

 Vertigo antivertigo. — In a road leading over Gloddaeth 



Mountain ; rather plentiful in a dry ditch on the Morfa. 

 V. pygmaea. — Under stones on the Great Orme; also near 



Penrhyn Farm, by Little Orme. 

 Clausilia rugosa var. tumidula. — Gloddaeth Mountain. 

 Gochlicopa lubrica var. hyalina. — One specimen on Great 



Orme. 

 C. tridens, is given at Llandudno in " Rimmer " — as found 



by a Mr. Thomas. 



I am rather surprised that Mr. Roebuck missed If. 

 ericetorum, as it seemed well disseminated, though not ubiqui- 

 tous on the Morfa. •
