OYSTER ATTACHED TO MACTBA SOLID A.

On 6th September, I picked up, on the shore at Magilligan Point, County

Derry, a large oyster shell fixed to a single valve of the small bivalve Mactra

solida. The latter was firmly attached to the oyster and the space between

the two was filled up with shelly substance. When the oyster was quite young it must 'have fixed itself to the empty shell, and grown to it, just as

young oysters often fix themselves to stones.

CONVOLVULUS HAWK-MOTH IN BELFAST.

A much battered female Convolvulus Hawk-Moth (Sphinx convolvuli) was captured' on the grass in front of the Northern Parliament House, Belfast, on 7th October, by Mr. Richard Lynas, and brought to me for identification.

BOTANICAL SIFTINGS.

CEPHALANTHEBA ENSIFOLIA IN CO. DUBLIN.

Since the publication of Colgan's Flora of Dublin in 1904 quite a number of interesting plants have been found in the County, anxl strange to say the majority of fchese have come from Glenasmole^, in which is situated the Rathmines water works. This fact is strange, because Glenas

mole has attracted botanists for at least 130 years, and even in the days of

Templeton and Mackay it was a famous locality for the botanist. Yet what lis perhaps its most beautiful plant, and also perhaps the rarest known member of its flora, remained unreported until June 1929, when Mr. John, S. Rarrington brought me a flowering spike of Cepholanthera ensifolia Rich., the beautiful white orchid which in more popul

. jargon is called

the Narrow-leaved White Hellaboriine. A few days later I had the pleasure of seeing the plant growing in Mr. Barrington's station by a small rill

flowing into the north-east side of the lower reservoir in Glenasmole. Though there are several known stations for Cephalanthera in Co. Wicklow, its

possible presence in Dublin has, so far as I am aware, never even been hinted at. It is now, alas, a very rare plant in Ireland, chiefly confined to

damp spots in our fast vanishing oak woods, and its presence in 1929 so near the city of Dublin is no doubt due to the fact that the waterworks has created a partial nature reserve of this portion of Glenasmole. This dis

covery of Mr. Barrington's makes one wonder whether this plant is really extinct in its old northern stations. I would suggest that during the first week of June next still another effort be made to re-find it an one or more of its former Co. Antrim stations. In Wicklow it grows in ground that is

spongy, preferring either the swampy sides of little rills or growing in wet

pans full of dead leaves on the flat ground an the oak woods.

KILLARNEY FERN IN SLIGO.

Miss Orofton has sent a specimen of this fern collected on the northern

slope of the Ox Mountains. Though on record from stations both north and south of Sligo, .it has not been recorded from that county before. The finder describes the plant as forming a good patch under a

large bouldsr. A new station for the Killarney Fern is always welcome. For obvious reasons I withhold the exact locality.
