FIELD NOTES. 
BIRDS. 
Peregrines at Bempton.—This year the Peregrine Falcons. 
have returned to their usual site at Ravencliff, on the Bempton 
cliffs. There are two young ones, and it is pleasing to report 
that, as a result of the stringent watching that has been kept 
by the ‘ climmers’ and others, the birds have been successfuliy 
reared.—E. W. WADE. 
Dipper using same nest twice.—A Dipper built its nest 
on the rock above a small waterfall near Beamsley Moor. It 
has done this for several years past but this year the first 
lot of eggs was taken by someone. After a short interval the 
bird laid another clutch in the same nest and is now feeding 
a lusty brood.—R. FORTUNE.

GEOLOGY. 
Macropoma mantelli in the Lincolnshire Chalk.— 
Among some of the fossils recently obtained from the large 
chalk quarry at South Ferriby, Lincolnshire, is:a,small object 
very much resembling a fir cone. I have not seen anything 
of the kind in the North of England chalk previously, but 
they seem to be known to the quarrymen, who call them 
‘fossil fir cones.’ This particular specimen was obtained in 
the Lower Chalk at a depth of twelve feet below the Belem- 
nitella plena zone. Mr. C. Davies Sherborn informs me that 
it is a coprolite of Macropoma mantelli Ag., and that it is not 
uncommon in the chalk of the south of England. So far as 
I can find, however, it does not appear to have previously 
been recorded for the Lincolnshire chalk.—T. SHEPPARD.

ARACHNIDA. 
Gamasus ignotus in Yorkshire.—I have received another 
specimen of this curious Gamasid (see The Naturalist for 
March) from Mr. Winter, of Shipley. They were collected by 
Mr. Castle at Kirkby Stephen. This is another locality, con- 
sequently the mite may be widely distributed and perhaps not 
uncommon. In Mr. Soar’s drawing no shoulder bristles are 
shown, and no doubt these had been rubbed off before Mr. 
Soar received the mite, but in this more recent specimen they 
are very much in evidence, and are long, straight, and pointed— 
dagger-like. This is of some importance, since Koch, in his 
Uebersicht, divides these mites into those with shoulder bristles, 
those without them, and those having shoulder bristles knobbed 
at the free extremity. Their absence may therefore be only 
accidental, in which case identification may be the cause of 
error in diagnosis.—C. F. GEoRGE, Kirton Lindsey.
