Fissidens rufulus B. and S. Confirmed in fruit in its station in 
River Wharfe (V.C. 64). 
Leptodontium flexifolium Hampl. Found in fruit on Moughton 
(V.C. 64). 
Trichostomum mutabile Brach. var. lophocarpum Schp. Found in

Zygodon lapponicus B. and S. Confirmed on Ingleborough (V.C. 64). 
Myurella julacea B. and S. Confirmed on Ingleborough (V.C. 64). 
Hepatics. 
Ptilidium pulcherrimum (Web.) Hampl. A welcome confirmation 
of its presence in V.C. 64, by its discovery at Eldroth. 
Marchesinia Mackair (Hook) Gray. Confirmed in Ingleton Glens by 
its discovery in plenty in another habitat from than in which it was 
originally found. 
In conclusion, emphasis is placed on the appeal made last year that 
old records of rare mosses should be followed up in order that definite 
information can be available as to which of the rare species can be con- 
sidered extinct in the county. 
Ecological Committee (Miss D. Hilary, B.Sc.) : — Two meetings 
have been held, one at Skipton on the occasion of the Annual Meeting, 
and the other a field meeting, May 7th. A second field meeting arranged 
in October did not take place owing to the impossible weather conditions. 
At the May Meeting the plots which last year were staked out on Moughton 
Fell for the investigation of the degeneration of the Juniper Scrub, were 
revisited and a few new records made. Another plot was entirely cleared 
of vegetation so that any invasions may be recorded in subsequent visits. 
Several exposures were made in the Juniper Valley, and the nature of 
the soil and the acidity at different depths was recorded. It is hoped 
later to obtain a more detailed record of soil analysis and acidity. 
Mycological Committee (Dr. J. Grainger) : — The Committee has 
continued its activities during the year and has been represented on 
each of its general excursions. Its annual Foray was held at Kirby - 
moorside from September iyth-22nd, when excursions into the valleys 
which run northwards to the moors were arranged, and a large number 
of species was collected. The Chairman, Mr. J. W. H. Johnson, M.Sc., 
F.I.C., presided over the Annual Meeting held on the 17th, when Mr. 
A. E. Peck was elected Chairman for the ensuing year. Miss K. 
Moorhouse was elected a member of the Committee ; the Hon. Secretary, 
Representative on Executive, and Recorder being severally re-elected. 
GEOLOGICAL SECTION. 
Glacial Committee : — -Renewed attention has recently been paid 
to the coast sections in Holderness, and Hull members have been active 
in a re-examination of the Boulder Clays from a stratigraphical aspect. 
A new classification of these clays has recently appeared in The Naturalist 
from the pen of Mr. W. S. Bisat, and members are invited to test the 
validity of his conclusions on the coast and in inland sections.
