A MONOGRAPH 



OF THE 



BRITISH FOSSIL CRUSTACEA 



OP THE 



ORDER MEROSTOMATA. 



PART IV. 



Genus 3. — Stylonurus, Page. 1856. 



To the acuteness and discrimination of Professor Page, P.G.S., we are indebted for 

 the earliest indication of two very well-marked genera of Palaeozoic Crustacea of the order 

 Eurypterida, namely, Slimonia and Stylonurus} Slimonia has already been figured and 

 described in the preceding part of this Monograph (pp. 105 — 120), and Stylonurus in 

 the ' Geological Magazine' (1864, vol. i, p. 197), and in the ' Quarterly Journal of the 

 Geological Society ' (1865, vol. xxi, p. 482). 



During a visit to Scotland early in 1864, I spent a week with my friend Mr. James 

 Powrie, F.G.S., at Reswallie, which enabled me to examine the localities in Forfarshire, 

 whence the Devonian species of JPterygoli, Stylonuri, &c, have been obtained. Upon 

 that occasion, and also upon a subsequent visit in 1867, I had the great advantage of 

 studying, not only Mr. Powrie's fine collection of palaeozoic fossils, but also the collections 

 of Lady Kinnaird, at Rossie Priory, of the University of St. Andrew's, the Watt Institu- 

 tion, Dundee, the Natural History Museums of Arbroath and Montrose, the Andersonian 

 and Hunterian Museums in the University of Glasgow, and the Museum of Science and 

 Art, Edinburgh ; besides the private collections of James Armstrong, Esq., and others, 

 in both Edinburgh and Glasgow, containing many fine examples of these palaeozoic

 Mr. Page, however, has published no descriptions of these fossils, and bis woodcut, figures, and explana- 

 tions appended thereto are only partially correct.
