Dr. H. Woodward—On Arthropoda of Coal-measures. 543 
Dr. H. Dukinfield Scott, F.R.S., has figured a Calamite node from 
Sparth obtained by Mr. W. A. Parker, F.G.S., in 1891, in his ‘ Studies 
in Fossil Botany,” fig. 11, p. 35. Other figures will be found in 
Professor A. C. Seward’s ‘“‘ Fossil Plants,” vol. 1, 1898: p. 310, fiz. 73; 
p. 316, fig. 77, showing nodes and buds; p. 330, fig. 85 (linear leaves 
of a Calamite). 
The above specimen was obtained by Messrs. W. H. Sutcliffe, 
F.G.S., and Mr. W. A. Parker, F.G.8., and presented to the British 
Museum (Natural History). 
8. Eoscorpius (Mazonta) Warpineteyr, H. Woodw., sp. noy. 
Since the discovery by Mr. W. A. Parker, F.G.S., of the nearly 
erfect specimen of a fossil Scorpion in the Middle Coal-measures at 
Sparth Bottoms, Lancashire (described and figured by Messrs. Walter 
Baldwin and W. H. Sutcliffe, F.G.S., in 1904; see Quart. Journ. 
Geol. Soc., vol. lx, pp. 394-399, figs. 2, 3), another less perfect 
example belonging to a distinct species has been forwarded to me for 
examination. It presents upon the two split surfaces of an irregularly

abdominal segments attached; the post-abdomen is not preserved. 
In front of the head-shield the two chelicerz (f.) are seen, and one of 
the pedipalps (p.) or maxillary palpi on the right side and a detached 
portion of the other on the opposite side’; also parts of three or more 
of the imperfectly preserved ambulatory legs (/., 7.), which appear to 
have had only a simple single claw (noé claws) at their extremities.

with their lenses directed forwards; they are placed near the centre
