Lough Swilly. I have gathered it also westwards in the county, 

 often fresh, and do not think it rare. 



Tellina balthica, Linn. (T. solidula). — Dublin and Donegal, 

 common on muddy sand. 



T. tenuis, Da Costa.— Dublin and Donegal, common on sand. 



T. squalida, Pulteney {T. incarnata). — Dublin and Donegal, 

 frequent; often found quite fresh on sandy beaches of Lough 

 Swilly and elsewhere. 



T. donacina, Linn. — Dublin: I gathered fresh specimens 

 after a storm, in 1881, at Portmarnock. Several fine examples 

 were shown to me in Miss Willan's collection from the same 

 locality. Like several other interesting shells that used to be 

 found on this strand, the present species is now almost un- 

 known. A growth of glar, or ooze, appears to have stretched 

 along the coast outside, to the destruction of several clean- 

 feeding animals.

OKNITHOLOGICAL NOTES FKOM NOEFOLK. 

 By J. H. Gukney, F.Z.S. 



The following diary of ornithological events in Norfolk, for 

 the year 1891, comprises all that is likely to be considered of 

 more than local interest : — 



The frost, which had lasted for eight weeks, broke up on 

 Jan. 23rd, there having been only three nights in fifty-one days 

 on which it did not freeze. The memorable frost of 1860-1, 

 though more severe, did not last so long, being over in thirty- 

 six days. At that time the late Mr. Stevenson communicated an 

 account of the effect of the severe weather in Norfolk upon birds, 

 to the pages of 'The Zoologist' (1861, p. 7389). Amongst other 

 things he noted the absence of Waxwings, and the abundance of 

 Smews and Wild Swans, characteristics which have marked the 

 winter of 1890-91. Then, as now, all birds suffered. According 

 to the testimony of our meteorologists (cf. Trans. Norf. and 

 Norw. Nat. Soc. v. 191) the cold was greater in 18G0-61 than in 

 1890-91 ; but it was not the cold, but the starvation produced by 

 it, which tamed the Wild Ducks, killed the Redwings and Field- 

 fares, and drove the hungry Brent Geese into our harbours.
