646 A CONTRIBUTION TOWARDS A KNOWLEDGE OF THE 



A Contribution towards a Knowledge of the British species 

 of the Order Syniphyla. 



By Richard S. Bagnall, F.E.S., F.L.S. 



(Plate xix., figs. i-io). 



Until 1903, when Professor H. J. Hansen monographed the 

 Order Symphyla in the Quarterly Journal of Microscopical 

 Science (xlvii., pp. i-ioi, pis. 1-7), little was known about the 

 species. As long ago as 1845 a British naturalist, Newport, 

 described the species commonly known as Scolopendrella 

 inunacjilata, and from that day to this Scutigerella imniaculata 

 (Newp.) is so far as I am aware the only species recorded 

 from the British Isles. 



In 1907 I collected from various localities forms of 

 Symphyla, which included, so far as I could discriminate, 

 Scutigerella imniaculata (Newp.), S. caldaria, Hansen, Scolo- 

 pendrella vulgaris, Hansen, and an apparently closely allied 

 species, this latter animal being found plentifully amongst 

 the submerged sand and shingle by the sides of the Derwent 

 at Winlaton Mill. 



Unfortunately this collection had been mislaid, but as I 

 have discovered S. vulgaris in various localities this year, and 

 have, through Dr. Jackson's kindness, had the additional 

 pleasure of examining S. notacantha, Gervais, it would seem 

 desirable to record the four species enlarged upon hereafter, 

 of which S. caldaria, S. vulgaris, and S. notacantha are 

 distinct and interesting additions to the British fauna. 



As Professor Hansen's very important, exhaustive and 

 interesting monograph is written in English, and published in 

 an English work easily accessible to all scientists, it will not 

 be necessary to enlarge upon the characters of the various 

 species, nor to figure them in detail. In fact I write this 

 paper in the sincere hope that some British naturalist seeing 

 it will take up the study of the British species, and I shall 

 gladly lend my material to any one intending to study the
