YORKSHIRE NATURALISTS AT HATFIELD CHACE. 85 



Mr. W. E. Clarke, F.L.S., in reporting for the Vertebrate Section, 

 stated that 21 species of birds had been observed, including 14 resi- 

 dents, and seven summer visitors. Noteworthy amongst them was 

 the Stonechat, a bird very locally distributed in Yorkshire, and the Hen 

 Harrier, a dead specimen of which had been picked up on the moors. 



Mr. W. D. Roebuck, F.L.S., in reporting for the Conchological 

 Section, observed that 21 species of Mollusca had been collected, 

 18 of which were fresh-water species, including LinmcBa glabra 

 (abundant in one of the drains), Sphceriuui lacustre^ Valvata cristata, 

 etc., and three terrestrial species. The district was remarkably 

 deficient in land species. 



In the absence of the secretary of the Entomological ^Section, 

 Mr. Roebuck also stated that a number of insects had been reported. 

 The most interesting finds were larvae of Emperor Moth, Fox Moth, 

 Eiibolia cerDinaria^ several moths, and a number of fine caterpillars 

 of Trichiosoma vitellince. 



For the Botanical Section, Air. P. Fox Lee, phanerogamic 

 secretary, the only officer of the section present, reported that the 

 botanical members had had a rare field-day. At this late period of 

 the year and especially after the prolonged hot summer, it could not 

 be expected that very many of the phanerogams would be noticed in 

 bloom, and there was little to add to the known flora of this part of 

 South West Yorkshire. Compensating somewhat for the scarcity of 

 plants in bloom, a sight long to be remembered was the profuse 

 fruiting of the blackberries, the oak, the guelder rose, the dog rose 

 {Rosa lutetiana Leman), and the hawthorn. On the heather-clad 

 expanse of Hatfield Chace, a wild primeval bog, also on the banks 

 of the dikes and drains, several of the typical peat-loving plants were 

 observed. The best plant ' find ' on the Chace was Andromeda 

 polifolia L., a rare member of the Ericacece, with pink, waxy globose 

 flowers. It was fairly abundant, scattered among the Ling and 

 Cross-leaved Heath. A diligent search was made for the three 

 British Sundews, all of which occur on the adjoining larger tract of 

 Thorne Waste, but only one of them, Drosera 7'ot2indiJolia L., was 

 found. There were fine fruiting bushes of Myrica gale L. on the 

 Chace, but not a trace of Osniunda rcgalis L., once said to grow 

 here in thickets (quite likely places), could be made out. Besides 

 these, on the Chace proper, the following species worthy of mention 

 were seen far advanced in the * sere and yellow leaf ' :—j£^//7^'/V//;// 

 angustifoliuui L., Rhynchospora alba Vahl, and Eriophoruui vagina- 

 turn ]>. In the drains and on the })eaty banks of ditches occurred 

 Stellaria aquatica Scopoli, Siellaria glaitca With. (H. Payne), Hydro- 

 cotyle vulgaris L., Hippicris vulgaris L., Potaniogeton pusillus var. 



March 1888.
