Dr. H. Woodward—On Arthropoda of Coal-measures. 547 
has noticed four species in Bohemia alone; one is found in Bavaria, 
one in Silesia, and at least two in our own coal.” If we follow 
Professor Fritsch’s classification and include, under the Anthraco- 
martide, Anthracomartus, Brachypyge, Anthracosiro, Eotrogulus, and 
Vratislavia, we should have to record fourteen species in this very 
widely distributed Carboniferous family of Opiliones. 
1. The first recognised form of British fossil Arachnids of the order 
Opiliones was described by me in 1871 (see Gror. Mae., Vol. VIII, 
pp. 385-388, Pl. XI) under the name of Lophrynus Prestvici, Buckl., sp. 
This was originally noticed by Buckland in 1836, from a less perfect 
specimen, in his ‘‘ Bridgewater Treatise,’ who referred it ‘‘to the family 
Curculionids, of which the diamond beetle is a familiar example.” 
He adds: ‘‘ the abdominal rings are very distinct. I shall designate this 
insect by the provisional name of Curculioides Prestvicii””’ (Buckland, 
vol. 11, 1836, pp. 76-77, pl. 46, fig. 2; fig. 1 op. cit. has not been 
identified). Locality, Coalbrook Dale. 
2. The second was figured and described in the GrotoeicaL 
Magazine for 1872 (pp. 385-387, Pl. IX, Figs. 1, 2) under the name 
of Architarbus subovalis, H. Woodw., from the Coal-measures of 
Lancashire, an Arachnide with an elongated form of body. It 
measures only 16 mm. in length and 7 mm. in greatest breadth, but is 
more evenly oval in form than is Geralinura Sutcliffec, which is more 
nearly elliptical in outline (see Fig. 4 of this paper). 
3. The fragmentary remains of an Arthropod figured and described 
by J. W. Salter in 1863 as Hurypterus mammatus, Salter, from the 
Coal-measures of Pendleton, Manchester (see Quart. Journ. Geol. Soc., 
vol. xix, p. 84; and Grox. Mae., 1873, p. 105, Figs. 1, 2), are 
still known only from portions of body-segments, but there is little 
doubt in my own mind that they are parts of a large Arachnide. 
They agree closely with similar Arthropod remains described and 
figured by Jordan! under the name of Arthropleura armata, Jordan. 
Similar specimens have come into my hands from the Coal-measures 
of Fifeshire, collected by Mr. J. W. Kirkby, F.G.S.; from the Coal- 
measures of Radstock, Somerset, collected by Mr. J. McMurtrie, F.G.S. ; 
and from the Coal-measures near Manchester by Professor Sollas. 
To these I hope to refer again shortly. 
4. Mr. R. I. Pocock has contributed so largely to our knowledge of 
the recent Arachnida that one is not surprised at his interest also 
in fossil forms (see his paper on ZHophrynus and allied Carboniferous 
Arachnida in the Geotoeicat Macazine, 1902, pp. 439-448 and 
487-493, with figures of Hophrynus, Brachypyge, and -Anthraco- 
martus, pp. 490-491). 
5. In 1903 Mr. Pocock continued his researches and described 
a new Carboniferous Arachnid, Anthracosiro Woodwardi, gen. et sp. 
noy., Grou. Mac., 1903, pp. 247-251, Figs. A, B. 
6. He described a second species of Anthracosiro (A. Fritscht, 
sp. nov., op. cit., 1903, pp. 405-408).

measures of Saarbruck, Rhenish Prussia. See also Pal. Soc. Mon. Merostomata,
