Curious Nesting Places. 
Some most amusing and curious places are at times chosen 
by our feathered friends for the purpose of their nidification. 
A very curious instance of this came under my notice a short 
time ago in a garden at Up mills ter, in Essex, where a pair of 
tom-tits ( Parus cceruleus) had built their nest in an old disused 
iron pump, the nest being built on the sucker and the birds 
making their entry through a small hole in the top and their 
exit through the spout. Another curious distance was that of 
a pair of wrens ( Troglodytes patvulus) building in a carcass of a 
carrion crow which had been shot and hung on a tree as a 
warning to others. This nest was exhibited for some time in a 
tavern at Colchester, in Essex. Blue Tit. 
CoLIAS EDUSA IN THE HASTINGS DISTRICT. 
I have found this species particularly abundant throughout 
the district this season ; the first specimens I saw early in June 
and the species gradually became more abundant until August, 
after this month the numbers began to decrease, the last 
specimen I saw about the middle of October. I managed to 
take five specimens of the pale variety helice and took another 
when collecting at Lewes, where the “ clouded yellows ” were 
very common but by no means easy to capture ; I also found 
the species common at Eastbourne, but saw none of the pale 
variety there. Of Colias hyale (the pale clouded yellow), I 
only took four specimens and saw a few more, all in this district. 
I cannot remember edusa being so abundant before, although I 
found it somewhat common here in August, 1885 and 1886.

Shells at the Wren’s Nest. 
Allow me to supplement Mr. Bath’s note, on the above, in 
the October issue of the Naturalists’ Journal. As no 
mention is made therein of the Vertigos and Pupas , I may say 
the following are found here, viz. V. edentula and pygmoe, and 
Pupa umbilicata and marginata. Among the Helices are wanted 
the following to complete the list given : H. rufescens , H. pygmoe , 
Id., rapes iris, and H. pulchella (rare). The var. lubncoides of 
Cocklicopa lub)ica is present together with var. dubia of Clausilia 
rugosa and var. alba of C. laminata. This last var. is rare here. 
H. ericetorum is very variable in its appearance, and while some 
years I have taken it almost as commonly as H. nemoralis , in 
others I have only succeeded in finding dead shells. This has 
been especially marked in this district in the case of the Hay 
Head (Walsall) locality. Mr. Bath should know his Black 
Country well, so that I need not say where the above locality 
lies: if he has not already been there, I would recommend him 
to take a hasty journey thither as soon as possible and judge for
