anything to do with its southern migration I cannot say, but the bird 
appeared in other respects perfect in form and condition.—E. H. Ropp 
(Penzance). 
[The Grey Phalarope, when going northward to breed in spring, 
apparently travels by a different route to that which it takes when migrating 
southward in autumn. At the latter season it passes through the British 
Islands often in large numbers, but in spring it is very rarely seen in 
the red plumage. This change of route is very curious, and deserves 
investigation.— ED. | 
Cuckoo Lavine Two Ecos 1n Onr Nest.—About two years ago, I found 
two Cuckvo’s eggs in a Hedge-Sparrow’s nest, both apparently laid by one 
bird, as neither was similar to any other Cuckoo's egg I have ever taken, 
but more resembled the Pied Wagtail’s eggs in colour. I mention this as 
in the Introduction to “ Montagu’s Dictionary of British Birds,” it is 
stated that “Where two eggs have been found in one nest, they certainly 
were laid by different birds.” I think the above affords strong proof that 
one Cuckoo does sometimes lay two eggs in the same nest.—ARTHUR 
BeaLe (Chiddingstone, Kent). 
Biackcap 1x County Dusirn.—On two occasions, during the second 
week in June, I observed a male Blackcap warbler (Sylvia atricapilla) in 
my garden by the Liffey, near Lucan, Co. Dublin. On both occasions it 
was feeding on cherries, under a net which hung in the tree. I never saw 
it in this county before.—J. F. Suackieron (Anna Liffey House, Lucan). 
[The Blackcap, although a regular summer visitant to Ireland, appears to 
be very local there.—Eb. ] 
A New Fossit Birp.—From a recent Bulletin of the ‘United States 
Survey of the Territories,’ it appears that the remains of a passerine bird 
of high organisation have been discovered at Florissant, in Colorado. 
Although certain portions of the head are wanting, the remains include the 
greater part of the skeleton and nearly all the bones of the anterior and 
posterior extremities. The impressions of the wings and tail on the rock are 
so clear as to show even the shafts and barbs of the feathers. The bird was 
evidently of arboreal habits and well-developed powers of flight, and although 
the absence of bill renders it impossible to decide with certainty the family 
to which the species may have belonged, it is thought to be allied to the 
Finches. Mr. J. A. Allen has described it under the name Paleospiza bella. 
A Rary Crustacean From Mount’s Bay, Cornwatu.—lI have just had 
brought to me the tubes of a large colony of Cerapus of some sort, found 
attached to a rock near St. Michael’s Mount. I am unable to determine 
the precise species, as my informant, with the best possible intentions,
