NEW BRITISH LICHENS. 



279 



JOSEPH A. MARTINDALE, 



I have recently gathered the following lichens, new, so far as I know, 

 to the British Flora : — 



1. Parmelia isidiotyla Nyl. in Flora, 1875, P- 8 - On walls near 



Cliburn, Westmoreland, and near Penrith, Cumberland. 



2. Paimularia lepidiota (Smrft.) Nyl, Scand., p. 290. Lamy., 



Lich. de Cauterets, p. 34. On Andrceas and other mosses, 

 Red Screes, Westmoreland. Nylander has described this 

 plant at page 124 of his Lich. Scand., under the name of 

 P annaria praztermissa. 



NOTE— MICRO-ZOOLOGY AND BOTANY. 



Microscopic Life near Askern. — The report of micro, work at the 

 Askern meeting on the 20th May, must of necessity be somewhat meagre, owing to 

 the prevalent flooding of the water-courses and land at the time. The following 

 were, however, noted: — Entomostraca: Cy clops quadricoriiis,Canthocamptusminu- 

 tus, Diaptomus castor. RhizopodS: Arcella vulgaris, A. aculeata, Difflugia sp. 

 INFUSORIA: Duisbryon sertularia, Paramecium sp. , Trachelitis lamella, Chceto- 

 notus sp. , Euglena pyrum, E. viridis, Chilodon cuculluhis. MlCRO-FUNGI : 

 Puccinia anemones (Campsall), ALcidium ficarice (abundant in Burghwallis Wood), 

 and Podosph'cera clandestine (on hawthorn in road from Campsall to Burghwallis). 

 Alg/E : The Diatoms were plentiful, but of common species, Pinnularia, Navicula, 

 and Diatoma, the chief feature being the large floating masses of Diatotna elon- 

 gateim in the peaty ditches at Campsall. Of DesmidE/E few were seen, viz.: 

 Cosmarium crenatum, C. pyramidatum, ClOsterium lunula, CI. acerosum, and a 

 new Yorkshire form, which I have elsewhere described as CI. eboracense. Among 

 the unicellular Algae a peculiar form was kindly pointed out to me by Major Bacon 

 Frank, in the pools at Campsall. Of minute size (the little cells only measuring 

 •000063 in. to '00015 m< ) ^ covered, in irregular patches of pink hue, several square 

 yards at the shallow end of the pool. It seemed to grow alike upon the debris 

 leaves or dead sticks. On examination I find it is the Pleurococcus roseo-persicinus 

 ' Peach-bloom Pleurococcus' (Kiitz.) Rabenhorst ; a rather interesting discovery, 

 as I have never before seen it in the county. Other unicells were Pandorina 

 morum, Goninm pecto rale (both universal), and Chlorospha;ra oliveri. — W. Barweli.

Spurn Head. — The learned author of 'The Geology of Holderness,' 

 published last year among the Memoirs of the Geological Survey, states at p. 1 01 

 of his very able and interesting work that ' previous to the 17th century an allusion 

 in Camden's Britannia (published in 1586) is the Only clue we have to the ancient 

 form of Spurn Head . . .' &c, and on p. 102 he asserts that ' the first survey 

 of Spurn Head was that made by Capt. Greenville Collins, Hydrographer to the 

 King, in 1684.' Mr. Clement Reid has evidently not seen the map of Yorkshire 

 issued in 1577 by Christopher Saxton, the first English chorographer, and has not 

 referred to the edition of the ' Britannia' of 1607, in which the map is reproduced. 

 Saxton's epitaph, given by Tanner, informs us that the maps of England were 

 made from an actual survey which took up nine years. The map of Yorkshire 

 shows the form of Spurn Head very distinctly. A MS. chart of the Humber in 

 Lord Burleigh's collection at the British Museum is also very instructive, though 

 perhaps not very accurate. — Lewis L. Kropf, 37, Margaret Street, Hull, June 

 12th, 1886. 



Sept. 1886.
