■J'OMLIN: notes on ^rARINK MOLLUSCA OF NORTH WALKS. 3 I 



Sepia biserialis DeMont. — Cymmeran Bay, Anglesea, shells 



only(L.). - 

 Eledone cirrosa I, am. — Occasionally at I.landudno near 



the pier. Also recorded from Puffin Island and Colwyn 



Bay (L.). 

 Sepiola atlantica d'Orb. — Menai Straits: Puffin Island (L.). 



P.S. — The Rev. H. Milnes writes as follows : — " The 

 Pecten taken at Barmouth was the ordinary white var. of 

 variiis: Cvliclina alba of ours really = C. cylindracea Penn. 

 . . . CJiitoii a/l'i/s must be wrong; it is some years since I 

 was at Barmouth, and I cannot just now find any notes of my 

 visit, nor any specimen of Ch. al/u/s from Barmouth in my 

 collection. I am very glad you wrote to me about them, as it 

 is a sad thing when errors get stereotyped." 



Arion minimus=intermedius Norm. — The slug intro- 

 duced to the British fauna by Dr. Scharff as Arion minitiius 

 Simroth, is probably a perfectly valid species, but it appears to 

 be identical with the earlier described A. intermedins Normand 

 ([852). It is the A. flavns of my 'British Naturalists' Cata- 

 logue of Land and Freshwater IMollusca,' p. 7 (1890). In 1885 

 I found an example at Kingsley, Staffordshire, and described it 

 •ssA. flavusm 'Science Gossip,' Oct. 1885, p. 224. In this 

 latter place some confusion is apparent owing to the fact that 

 the passage from ' I have recently found ' to ' central line of 

 the mantle,' was written as a footnote, but printed in the body 

 of the text. I meant to imply that Mr. Sutton's form was the 

 dubious form (really suhfuscus) referred to earlier, and did not 

 wish to connect it in any way with ray A. flaims (really inter- 

 niedins). A. ijitermedius has been recently re-described, and 

 the synonymy given by Pollonera (1890). — T. D. A. Cockerri.l, 

 December 12, i8go.
