56 The Irish NA 7inralist. tVeb. iS9&6

HooPoE (U.puPa e.ops).-One from Rosslea, Co. Fermanagh, i9th September, a very curious date for the occurrence of this bird, as it is generally on the spring migration and usually in the south of Ireland that it occurs.

RICHARDSON'S SKUA (Stercorarius crepidatus).-All the specimens of this bird I have met this autumn belonged to the dark form; one obtained Rathangan, 13th August, a good many from Cliffoney, Sligo, during September; amongst them a curious variety with patches of pure white on wings and breast.

POMATORHINEU SKTux (Slercorarizs pomatorhznus).-One from Killarney, October ioth, one on i4th, Ballinfull, Sligo, and another captured whilst eating a good-sized chicken at Ballinastragh, Gorey, Co. Wexford.

SQUACCO HERON (Ardea ralloides).-A beautiful specimen of this bird was shot at Waterville, Co. Kerry, 17th September, a young male in second year's plumage; the stomach was filled with remains of small crustacea; I have heard of another shot in Co. Cork same time, but have not particulars.

GREAT NORTHZRN DIVER (Colymbus glacialis).-In full summer plum. age, oUtained so late as i6th October, without a trace of the winter moult,

Kylemore, Connemara. A variety of the BALD COOT (Fulica atra), with almost half the

plumage pure white was obtained near Enniskillen, and a RoCK PIPIT (Anhus obscurus) with head, wings, and part of breast white, was shot near Bray.

]EDWARD WILLIAMS, Dublin.

GEOLOGY. Quartzlte.-It might, perhaps, be worth mentioning that on the

occasion of the Belfast Naturalists' Field Club excursion to Co. Donegal last year, I secured in the quartzite specimens of suncracks, ripple

marks, and raindrop marks, the two first being especially characteristic. All three are small hand-specimens chipped off large slabs of the formation, and were obtained in or close to the Seven Arches Cave, Portsalon. Should they be thought of sufficient interest either Mr.

Watts or Mr. Kinahan are very welcome to examine them. Their general appearance, excepting, of course, the matexial, is wonderfully like the Triassic sandstones of Scrabo, near Newtownards, Co. Down, as the markings seem to occur chiefly on thin fine-grained bands, which are of mud, in the Triassic stones. A lucky chance might even hit on a fossil in some of these less altered deposits.

ALEc. G. W smso, Belfast.

The Denudation of the ChaIk.-Prof. Cole contributes a paper on this subject to the GeologicalMagazine for December, i895. Particular re ference is made to the startling photograph, by Mr. R. Welch, showing the condition of White Park Bay, Co. Antrim, after the great storm of

December, 1894-a chaotic expanse of great blocks of Chalk, resting on a floor of tias, where on the previous day, and for years previously, an uninterrupted expanse of smooth sand had stretched.
