Northern Ncivs. 



mm. broad, very concave by the broad incurving of the margin 

 right down to the base, often iinsymmetrical ; in the narrow 

 blunt apex almost cucuUate and faintly toothed. Hyaline cells 

 of numerous fibrose bands, and on the leaf surfaces with 

 exceedingly numerous rows of very small pores in the commi- 

 sures, and those of the inner surface are for the most part 

 pseudo-pores. 



Chlorophyll cells in cross-section triangular to trapezoidal 

 (barrel-shaped according to Roll), emerging from the inner 

 surface or free on both sides, but the broad outer wall is always 

 on the dorsal surface. 



Mrs. Walker and her son, Mr. Gelson Walker, have presented the 

 valuable collection of fossil brachiopoda formed by the late J. F. Walker, of

An exhaustive article dealing- with lona Marble appears in 'The Quarry'

 reproduced by the three-coloured process. 



The North Lonsdale Field Club, formed in April last, has already over a 

 hundred members, and appears to be very enthusiastic in its work. Our

Under the name of Massaria theicola Y'eich. , our contributor, Mr. T. 

 Petch, B.A,, B.Sc, describes 'A Stem Disease of Tea' in Vol. IV., No. 4 

 of the circulars issued by the Royal Botanical Gardens Ceylon. 



Throug-h relying- upon a newspaper notice, in a note on page 413 of our 

 December issue, we erroneously attributed to the late John Farrah the 

 authorship of the 'Flora of Nidderdale ' in Speight's ' Nidderdale.' This 

 was written by Dr. F. A. Lees. 



Amongst the many valuable notes in the recently issued Journal of the 

 Quekett Microscopical Club, the following' are of particular interest to our 

 readers: — 'Notes on Pseudoscorpions, British and Foreign,' by E. Elling- 

 sen ; ' Three Water-mites new to Britain,' by G. P. Deeley ; and ' Some 

 British Spiders taken in 1907,' by F. P. Smith. 



In the December ' Geological Magazine,' Dr. Henry Woodward, F.R.S., 

 has some * Further Notes on the Arthropoda of the Coal-Measures.' In these 

 he figures and describes a number of interesting specimens from the well- 

 known locality at Sparth Bottoms, which are new to science : — Bellinurus 

 BaMwitii, H. Woodw. ; B. longicai(dattis, H. Woodw. ; Eoscorpins {Mazonia) 

 WardhigJeyi, H. Woodw. ; and Geralhinra Siifcliffei, H. W^oodw. 



We regret to learn of the death, early in December, of Robert Gilchrist, 

 of Scarborough, at the age of forty-three. He was a g^ood ' all round " 

 naturalist, and paid particular attention to botany, geology, and the 

 arachnida. In recent years, as a result of the Fungus Forays of the York- 

 shire Naturalists' Union, he gave much time to mycolog-y. He took a 

 prominent part in connection with the work of the Scarborough Field 

 Naturalists' Society, of which he was twice the president. 



W^ith reference to the record of Deleaster dichrous Grav. which appeared 

 on page 353 of our October issue, Mr. J. W. Carter, of Bradford writes : — 

 ' Mr. Bayford has evidently overlooked the fact that this species has 

 previously been recorded for the West Riding of Yorkshire. I had the 

 pleasure of taking six or seven specimens, all under one stone, in the bed of 

 the Greta, at Burton-in-Lonsdale, on the 23rd of May, 1903. Mine too, I 

 find, were all of the variety leachii Curt." (see the ' X'ictoria County Hist.').
