Dr. H. Woodward—On Arthropoda of Coal-measures. 539 
V.—Fourruer Notes on THE ARTHROPODA OF THE British Coat- 
MEASURES. 
By Henry Woopwarp, LL.D., F.R.S., F.G.S. 
OR some years past a Committee of Littleborough and Rochdale 
geologists, consisting of Messrs. W. H. Sutcliffe, Walter Baldwin, 
W. A. Parker, S. S. Platt, and others, have devoted themselves to 
the task of working out the beds of shale containing clay-ironstone 
nodules, a portion of the Middle Coal-measures at Sparth Bottoms, 
half a mile south-west of Rochdale Town Hall, in beds estimated to 
occur 135 feet above the Royley Mine Coal-scam. 
In the clay-ironstone nodules occur well-preserved ferns, Calamites, 
Sigillarie, shells of Carbonicola acuta and other Coal-measure 
lamellibranchs, whilst the number of Arthropoda obtained is probably 
unsurpassed in any locality of this formation.’ 
The first Arthropod obtained from Sparth Bottoms was noticed 
by Mr. Walter Baldwin, F.G.S., under the name of Prestwichia 
rotundata, Prestw., sp. (Trans. Manch. Geol. Soc., vol. xxvii, part 6, 
1901, pp. 149-155, with a plate); the second in 1908, by the same 
geologist, who identified it as Bellinwrus bellulus, Konig (op. cit., 
vol. xxviii, part 8, pp. 198-202). The third and most important 
discovery was made by Mr. W. A. Parker, F.G.8., namely, a new 
species of fossil Scorpion, which was described and figured in 1904 by 
Messrs. Baldwin & Sutcliffe under the name of Hoscorpius Sparthensis 
(Quart. Journ. Geol. Soc., vol. lx, p. 896, fig. 2). These geologists 
have continued their researches, of which a brief account was given 
by me at the York Meeting of the British Association (1906). Many 
subsequent finds have been most obligingly confided to me by these 
gentlemen, and through the kindness of Mr. W. H. Sutcliffe the 
specimens figured have since been presented to the Geological Depart- 
ment of the British Museum (Natural History), the only condition 
imposed being that they should be described. I am endeavouring 
gradually to carry out this part of the agreement. — 
Previously (Gror. Mag., 1905, Dec. V, Vol. II, pp. 483-444) 
I had described and figured various forms, namely: Anthrapalemon 
serratus, H. Woodw., sp. nov. (op. cit., pp. 438-439, Figs. 1, 2); 
Euphoberia Brownii, H. Woodw. (Fig. 3); and Xylobius moniliformis, 
H. Woodw., sp. nov. (op. cit., pp. 442-448, Fig. 4). In that paper 
I also gave a summary of several other Arthropods discovered and 
described from the Lancashire Coal-measures up to that date (1905). 
In June last I figured and described two new species of Lurypterus 
from the Coal-measures of Derbyshire? (Gror. Mag., 1907, pp. 277-282, 
Pl. XIII); and in September I gave a description of the brood-plates, 
or marsupium, lately discovered in several examples (evidently the 
females) of Pygocephalus, a primitive Schizopod Crustacean (op. cit., 
1907, pp. 400-407, Pl. XVIII), which was first obtained in 1857 
from the Glasgow Coalfield, afterwards from near Manchester, later 
from Dudley,’ and finally from Sparth, Rochdale.
