ia MISCELLANEA. 
Fresh-water Alge.—BSeveral interesting species have occurred 
to me recently, in our neighbourhood. At Ryton Spherozyga 
elastica(Ag.),Cylindrospermum spirale, and Draparnaldia cruciatw 
(Hicks,) in a ditch near Crag Lake; Raphidia viridis, on stones at 
the margin of a deep pond near the Brockley Whins Station; 
Tetraspora gelatinosa, in a pond near Charlton, on the North 
Tyne; Tolypothrix« distorta, abundantly on Mordon Carrs ; 
Physactis parvula, (Kutz), and Clathrocystis eruginosa, (Henfrey), 
in the moat at Raby Castle. The two last named were kindly 
sent to me by the Rev. A. M. Norman, and for their identifica- 
tion, I am indebted to Professor G. W. Arnott, and Mr. Roger ~ 
Kennedy of Glasgow. I may add, that, with a view to the 
preparation of a complete catalogue of the local species, I should 
feel obliged, if such of our members as are interested in the 
subject, would communicate to me any interesting specimens 
which may occur to them.—Jdid. 
Volvox globator.—This beautiful organism appears to be more 
generally distributed in our district than we have been used to 
suppose. For several years the only known locality for it was 
Prestwick Car, where it was found by Mr. Atthey. In a 
” 
recent part of the ‘‘ Transactions,” Mr. Norman records its 
occurrence at Sedgefield; and during the past year it has been 
noticed in several fresh places. According to newspaper report, 
it was found abundantly in a pond at Darlington, by some 
‘“‘minute philosophers,” attached to a temperance excursion. 
I detected it at Ryton in September, and also among some alge 
brought from Fardingslake near Marsden in October. Lastly, 
Mr. Norman informs me that he noticed it in the moat at Raby.

Botanical Notes.— During the summer I have noticed but 
few plants of any rarity in this district, viz: Phalaris Canariensis 
growing in a turnip field at Norton, and Medicago stativa 
(Lucerne), on September 13th, in a stubble near Billing- 
ham, the seed of it had doubtless. been sown by accident 
with the corn, as the plant is not cultivated for fodder in this 
neighbourhood. On the 28rd October I gathered Mumaria 
capreolata, which is rare here, in flower. I never before saw it
