whole body a beautifully distinctly reticulated appearance. The 

 shield is uniform grey, and the foot-fringe is pale and rather 

 dirty orange tawny, with the usual black streaks. This speci- 

 men is about half-grown, and was sent me by Mr. Kane on the 

 loth November, from the neighbourhood of Mallow, North 

 Cork (judging from the post-mark). With it were numerous other 

 slugs, an account of which I reserve for my paper for the Royal 

 Irish Academy. I will, however, here say that the slug-fauna 

 of Ireland, so far as Mr. Kane's numerous and extensive con- 

 signments show, has a marked character of its own, and offers 

 numerous forms of variation not usually observed by English 

 collectors.— W. Denison Roebuck, Sunny Bank, Leeds. 



Ancylus fluviatilis var. costata Fer. — This variety is 

 described by Baudon (' Journ. de Conch., 1884') as being dis- 

 tinguished from the type by striae, more or less marked, from 

 the summit to the base. Captain Brown (Recent ' Conch, of 

 G. B.') mentions a variety which exactly agrees with this defini- 

 tion as being found in a stream near Folkestone. This variety 

 ought therefore to be added to the British list. — T. D. A.

Pupa marginata var. brevis Baudon in Britain. — 



Amongst some shells collected by Mr. W. Denison Roebuck 

 on June 27th of present year, at Runswick Bay near Whitby, 

 I found a very characteristic specimen of this variety, which 

 has not previously been recorded as British. It is described by 

 Baudon as " Tres raccourcie, robuste, bourrelet epais, blanc au 

 peristome." The average size of the type as given by Dr. 

 Jeffreys is 0-133^ or about 3JE^ mill, and breadth o*6, the latter 

 presumably an error for o'o6 which is equal to about i}^ mill. 

 The specimen of var. brevis is 2 mill, long and about i^ mill, 

 broad, is composed of a whorl less than usual, and the mouth 

 being perfectly finished shows it to belong the edentate form of 

 the species. — J. W. Taylor.
