The Naturalist. 



pascuellus, EupEecilia angustana, &c,, &c. Mr. P. F, Lee, secretary for 

 phanerogamic botany, reported, upon the day's proceedings, that the 

 total number of phanerogams, ferns, &c., of London Catalogue observed 

 on the Common, as well as at Warthill and near the village of Strensall, 

 was 258. Of these, note should be made of the following, as they include 

 some good things rarely met with at the Union's excursions : — Drosera 

 intermedia, Polygala vulgaris, sub. sp. depressa, Stellaria glauca, Hyper- 

 icum elodes, Radiola millegrana, Spira3a Filipendula, Carduus pratensis, 

 Pyrola minor, Scutellaria minor, Daphne Laureola, Habenaria bifolia, 

 Carex dioica, C. pilulifera, C. distans, sub-sp. fulva, Aira caryophyllea, 

 JPestuca myurus, sub.sp. sciuroides, Nephrodium Oreopteris, Botrychium 

 Lunaria, Lycopodium inundatum. The Cryptogams (for which Mr. G. 

 Massee reported) appertaining to heathy swamps were abundant ; good 

 fruiting specimens of the following were obtained : — Pilularia globulifera, 

 Sphagnum rosellum, S. acutifolium, S. squarrosum, Meesia uliginosa, 

 Lastrsea Oreopteris, Lycopodium inundatum barren. Amongst algse and 

 fungi the most noteworthy were Yolvox globator, Chsetophora tubercu- 

 losa, Mougeotia genuflexa, Meridion circulare ; Omphalia campanella, 

 O. umbelliferus, Thelephora terrestris, and Tubulina cylindrica. For 

 the Geological Section no report was presented. In Vertebrate Zoology 

 Mr. Clarke, secretary, reported that most of the specimens announced in 

 the circular had been observed, and in addition to these the curlew. The 

 sandmartins, numerous on the common, were nestling in the turf-clad 

 marker's butts— the only habitat offered in the neighbourhood. Th& 

 water vole among the mammalia, the lizard (Zootoca vivipera) among the 

 reptiles, and the trout and stickleback among the fishes, were also 

 observed. 



Micro-aquatics at Strensall. — On our recent Y.N.U.. visit to Strensall 

 Common, I was the only collector of micro-aquatic plants, and I found a 

 rare store of good things," — some new to Yorkshire, and I almost think 

 new to England, as certain desmids which I found have only been 

 reported from Wales (A. W. Wills, of Birmingham, in his famous Capel- 

 Curig gathering), and Ireland (W. Archer, F.U.S., of Dublin). When 

 verified, I will send a full list, but at present will only mention the 

 following as a sample : — Microspora fugacissima, Aptogonum desmidium, 

 Glseocystis rupestris, G. ampla, Cosmarium pyramidatum, C. margariti- 

 ferum, C. cucurbita, Euastrum binale, E, elegans, E. didelta, Xanthidium 

 fasciculatum, X. octocorne, Zygnema stagnale, Z, stellinum, Staurastrum 

 dilatatum, S. furcigerum, S. anatinum, S. aristiferum, S. inflexum, S. 

 margaritaceum, Arthrodesmus convergens, A. incus, Polyedrium tetra- 

 hedricum, Pediastrum Ehrenbergii, P. Boryanum, Sphoerozosma verte- * 

 bratum, Anabaina circinalis, Yolvox globator (T. Hick), ditto, (W. B. T.) 

 It is to be noted that Diatomacepe were but few in number, and that 

 many common confervae and desmids are conspicuous by their absence ' 

 from this gathering. — W. B. Turner, Leeds, 24th July.
