NOTES FROM LANCASHIRE. 185 
Iimnea glabra.w—This seemed to me to become: suddenly 
abundant during 1877. At any rate I had always before that 
looked upon it as quite a rarity, but in the autumn of that year 
I found it plentiful in various ponds near the Bootham Junction 
signal-box, on Tillmire, in ditches along the sides of both Acomb 
and Knavesmire Woods, in various ponds and ditches on or near 
Strensall Common, and several other localities. Mr. Jeffreys 
mentions York as a habitat and it used formerly to be found at 
Langwith (B.) It also occurs now in the first pond at Askham 
Bog (R.); and in many ponds about Clifton, sometimes in 
abundance (H). 
Var. albida.— About Clifton (H.) 
Ancylus fluviatilis As there are so few streams round York 
adapted to the requirements of. this species, it is not to be 
wondered at that it is rare. It lives in fair numbers in stony 
places in the Ouse and also in the Foss, where the current runs 
over many large stones at Yearsley Lock. 
Ancylus lacustris.—Few and small in the Foss, at Hobmoor, 
Askham, and doubtless some other places. A sure method of 
finding it is to pull up the large flags and other weeds and care- 
fully examine them. Fairly abundant in a pond on the Wiggington 
Road (H.)

ORNITHOLOGICAL NOTES FROM LANCASHIRE. 
By F. S MrrcuHett. 
Tue following notes represent some of the experiences of 
myself and my coadjutor, T. Altham, for the last few years in 
Clitheroe and its neighbourhood. The town lies in the middle 
of the Ribble valley, which is both well wooded and well watered, 
and is bounded on one side by Pendle, over 1800 feet in height, 
and on the other by the lesser fells of Waddington and Grindleton. 
There is, therefore, plenty of variety of bird ground, and within 
a radius of three miles from Clitheroe seventy-three species breed 
yearly, from the Curlew to the Grasshopper Warbler, and from 
the Twite to the Landrail. 
IT have been for some years working at the birds of Lanca- 
shire, and should be very grateful for any aid in the way of lists
