FIELD NOTES. 
BIRDS. 
Bitterns in Holderness.—On the 12th January, a bittern 
was picked up near the Humber shore at Paull. The bird was 
in immature plumage and very poor in condition. On the 20th 
January, Mr. E. Stubbs received a fine mature example of 
this species. Mr. Stubbs informs me he had received three 
birds of this species within a fortnight, and in addition, two 
had been shot by a local gamekeeper. I have repeatedly 
noted the Bittern’in this district during the month of January, 
but never before in such numbers as recently.—STANLEY 
Duncan, Hull.

HYMENOPTERA. 
Willow Gall (Euura pentandrae) near Leeds.—On 
7th December last, at Alwoodley Gates, near Leeds, I observed 
this gall on the willows which for upwards of twenty yards 
line the right-hand side of the road leading to Shadwell. The 
tall bushes were completely overspread by the gall, and the 
twigs, hardly one of which was without one example at least 
were in consequence strongly bent and contorted. In their 
leafless condition and thus heavily burdened they were very 
conspicuous objects. The gall is caused by one of the saw- 
flies. In each may be from one to six or eight larve, and the 
flies emerge in April.—Wwmn. FALconeER, Slaithwaite, Hudders-

ARACHNIDA. 
Coryphzus simplex F.O.P.Cb. new to Lancashire.— 
At the end of July last, while collecting on the shore at Fair- 
haven, south of Blackpool, I took a female of this spider 
from beneath a tuft of Atriplex. It is one of the rarer British 
species, with as yet few recorded stations. Originally dis- 
covered, both sexes, in some quantity, in 1891, in the cellar of 
a brewery, Cannock, Staffordshire, it has since been met 
with at Brierley Hill, in the same county, (several examples), 
and on the coasts of Yorkshire (Scarborough), Northumber- 
land, and Cumberland ; all solitary specimens. The present 
record is thus a new one for the county of Lancashire.
