he names EH. Beecheri.' From the presence of parts of two long 
slender, ridged, non-spinose appendages associated with the body in 
the position which would have been occupied by the swimming-feet, 
J am led to surmise that this may possibly prove to belong to the 
genus Stylonurus ; but I offer this suggestion with extreme caution 
and reserve, well knowing the great care and vast experience of 
Prof. James Hall in dealing with this group of ancient Merostomatous 
Crustacea. 
Body-segments of Eurypterus Wilsont, H.W. (natural size), Coal-measures, 
Radstock, Somerset. 
Before concluding this note, I desire to call attention to a very 
interesting discovery made by Mr. Edward Wilson, F.G.S., of the 
Bristol Museum, of a part of the body of a Eurypterus (see woodcut) 
from the true Coal-measures at Ludlow’s Pit, Radstock, Somerset. 
The specimen consists of the first six body-segments only, following 
immediately behind the head: they measure together 533 millimétres 
in length by 52 mm. in greatest breadth. The first segment, as is 
constantly the case, is shorter than any of the others, being only 
4; mm. deep; the 2nd is 8 mm.; the 3rd 11 mm.; the 4th, dth, and 
6th are each 10 mm. deep. The first segment is nearly straight and 
42+ mm. broad; the segments gradually become more arched, and 
increase in breadth slightly to the 4th, which is 52 mm. broad; 
contracting slightly to the 6th segment, which is 474 mm. broad. 
The Ist, 2nd, and 8rd segments have their lateral borders nearly 
straight, but the 4th, 5th, and 6th are rather more expanded and the 
posterior angles are produced and rather more pointed. The surface 
of each segment is marked by squame which are extremely numerous 
and very minute along the anterior border of each segment, but near
