BOTANY.— The Botanical Section will be officially represented by Dr. 
T. W. Woodhead, F.L.S. 
Flowering Plants. — The district will be found to be an interesting 
one to the botanist. The following are amongst the plants that will be met 
with : — Dyoscra rotiindi folia, Campanula latifolia, Pediadatis palustris, P. sylvatica, 
Agrimonia eiipatoria, Scrophidaria nodosa, Mimulus luteus, Euphrasia officinalis, 
Scutellana galericulata, Trientalis eiiropcsa, and Briza media. 
Mr. Frank Elgee, F.G.S., writes : — Heather moorland is well developed on 
Great Ayton and Kildale Moors. Easby Moor is a good example of the Mat 
Grass and Heather Moor, a type that often prevails at the moor edge in 
Cleveland. Lonsdale is a characteristic moorland valley with great Jiincus 
swamps on its floors The hill slopes are largely clothed with Bracken and 
Grass, and sometimes Gorse is abundant as on Cockshaw Hill 
Mosses and Hepatics.— Mr. W. Ingham, B.A., who will attend the 
meeting writes : — The following Bryophytes may be found close by Great Ayton. 
Mosses. — Polytrichum alpinum, P. formosum, Pleuridium axillare, Swartzia 
monfana, Fissidens exilis, F. incurvus, Pottia lanceolata, Weisia criapa, Hedwigia 
albicans, Tetraplodon mnioides, and Aulacomnium androgvnum. Mr. Mudd found the 
very rare moss, Oreas Mielichhoferi var. elongata on dripping liassic rocks above 
Ingleby Greenhow, and it would be very interesting to find this moss near Great 
Ayton. Its only other British habitat is on iron-bearing rocks above Loch 
Kander, S. Aberdeen, where it was refound in July, 1912. 
Sphagna. — These are to be sought for chiefly on Ayton Moor where grows 
the rare 6. obestcm. On Roseberry Topping grow S. cymbifolinm, var. glaucescens, 
S. papillosum var. normale. S. tur/aceiim, and 5. rufescens. These sphagna and others 
probably occur nearer Great Ayton. 
Hepatics. — Alicularia scalaris, Plagiochila asplenioides, Lophocolea bidentata, 
Lophozia Floerkii, L. incisa, Lepidozia setacea, Blepharozia ciliaris, and Radula 
compianata. 
Note. — The Basaltic Dyke close by should prove good ground for rare 
mosses and hepatics. 
Fungi. — The Yorkshire Mycological Committee will be officially repre- 
sented by its Secretary,' Mr. Charles Crossland, and other members. 
VERTEBRATE ZOOLOGY.— The Vertebrate Section will probably be 
officially represented. 
Mammals.— Mr. T. A. Lofthouse, writes : — The Badger occurs in the 
district, and the Otter in the River Leven. Others which have been noted are 
Squirrel, Stoat, Weasel, Hedgehog, Water Vole, Field Vole, Short-tailed Field 
Mouse, Shrew.

following interesting specimens have been noted, viz. :— Green and Spotted 
Woodpeckers, Jay, Pied Fly Catcher, Tree Creeper, Blackcap, Long-tailed Tit, 
Gold-crested Wren, Stock Dove, Woodcock, Snipe, Hawfinch, Night-jar, King-

of the Vertigoes having been taken. 
ENTOMOLOGY.— The Entomological Section will be officially repre- 
sented by Mr. G. T. Porritt, F.L.S., F.E.S. 
Lepidoptera. — Mr. T. A. Lofthouse, writes : — Many interesting species 
of Lepidoptera occur in the district to be visited, and a specimen of the Brim- 
stone Butterfly, G. Rhamni, was taken in the district as recently as 1911. Among 
the Macros occuring in the district are E. tithonus T. rubi, N. plantaginis and var. 
Hospita, N . Russula. C./urcula, N. dictaeoides, A . ligtistri, Noctu depuncta, N. siigmatica,
