Occurrence of a Pearl in Littorina littorea Linne. — In July, 1915, my 

 friend, Mr. Alexander C. Smith, of Claremonl, Perth, was staying at Westhaven, 

 Carnoustie, near the mouih of the Tay, where he collected some specimens of 

 Littorina littorea. On examining these, he found under the mantle of one of them 

 what appears to be a genuine pearl. It is 2 mm. in diameter, of a pale horn colour, 

 almost spherical, and slightly translucent. It is similar to the small brown seed 

 pearls, frequently found in U7iio margaritifer. So far as I am aware, this is the 

 first time that a pearl has been found in this species, or, indeed in any British 

 marine univalve. — Henry Coates {Read before the Society^ Oct. i6th, 1915). 



Zonitoides nitidus (Miill.) New to Herefordshire. — I found this species 

 fairly plentiful in the dried-up bed of the canal near Wellington Heath last June, 

 and a few days later obtained it again in marshy ground on the banks of the 

 Malhon Brook between Mathon and Old Country. In each case it was associated 

 with Succinea elegiins Risso and S. piitris L. , and in the second locality also with 

 a small dark form of Euconithis fiilvus (Mtill.) — probably \a.x. alderi Gray. It 

 seems rather remarkable that Z. nitidns should have been for so long overlooked 

 in Herefordshire, where there are many suitable habitats for it. Mr. J. W. Taylor 

 has kindly verified my determination. Mr. Tomlin writes that he took the species 

 in 1911 in damp ground in Stoke Edith Woods, and on the borders of the county 

 near Pontrilas. — Norman G. IIadden {Read befoic the Society, Nov. 10, 1915).
