404 MR B. N. PEACH ON SOME 
comparison with the Indian scorpions for size. I propose to name it from its 
exceedingly beautiful combs which are the most complex that have as yet come 
under my notice in the present collection. Fossil combs often turn up among 
the disjecta membra of scorpion, so that a specific character founded on these 
may be useful for recognition. The tuberculations on the under edge of the 
third joint of the walking limbs, and on the dorsal segments are sufficient to 
distinguish it from £. glaber, while the comb is quite distinct in shape from 
E. carbonarius (Meek and Worthen), and its limbs seem to be shorter and 
stouter. From &. Anglicus (Woodward), the shape of the palpi at once 
distinguishes it. 
Locality.—River Esk, four miles south of Langholm, Dumfriesshire. 
Horizon.—Near the base of the Cementstone group, Calciferous Sandstone 
series (Lower Carboniferous). 
Collector.—A. MACCONOCHIE. 
Eoscorpius, sp. (Plate XXIII. figs. 11 to 11a). 
A specimen which among other crushed and unrecognisable portions of 
a small scorpion shows more than half of a carapace which is distinct from that 
of E. tuberculatus. It has a corresponding groove mesially, near the anterior 
of which is set an eminence with two eyes directed forwards. The swollen 
cheek-like portions, however, are much more complicated by being divided by 
lateral grooves into three distinct portions on each side. One of these is small 
and elongated, well-covered with tubercles, and lies just within and parallel to 
the antero-lateral margin. The middle portion is the largest, and rises above 
the rest of the carapace, with steep sides all round, the side overlooking the 
mesial groove being steepest. This eminence is covered with large irregular 
pustules, some of which are compound, almost like a strawberry. The posterior 
eminence representing the hinder portion of the swollen cheek in £. tuber- 
culatus is triangular in shape and divided into two horns by a deep mesial 
depression and is almost free from tubercles. The postero-lateral angles are 
rounded, and enclose, with the outer margin of the eminence, triangular areas 
of the wrinkled test as in F. tuberculatus. Mesial eyes are two large simple 
ones, set in front of an elongated triangular eminence, which has its apex 
directed backwards. The eminence, as in &. tuberculatus, is nothing more than 
two connate tubes, which very gradually rise from the level of the floor of the 
mesial sulcus, and the long axes of which diverge at an angle of only 15° to 20°, 
no portions of the tubes being free, differing in both the latter characteristics 
from £. tuberculatus. Four lateral eyes are visible on the right antero-lateral 
margin. Behind the fourth the margin is incomplete, so that there may have 
been more. One of the lateral eyes is shown magnified in fig. 11a. 
Fig. 13 shows a portion of a carapace from Dalmeny railway cutting.
