On a New Species of Eurypterus (E. Brodiei), from Perton, near Stoke Edith, Herefordshire

In March 1869, the Rev. P. B. Brodie, F.G.S., communicated to the Geological Society a short account of the occurrence of remains of Eurypterus and Pterygotus at Perton (see Quart. Journ. Geol. Soc. xxv. p. 235). Mr. Brodie stated that the specimens collected at that time and submitted to me were not considered to be new; in fact they consisted, for the most part, of fragments of Pterygotus (P. Banksii) and Eurypterus § (E. pygmæus, E. acuminatus, E. abbreviatus, &c.), already noticed by Mr. Salter elsewhere. Since that communication was read, Mr. Brodie has again explored this locality, and has forwarded to me several parts and an almost entire example of a Eurypterus, which differs considerably from any species previously examined by me, and of which I beg to subjoin a short notice. The most perfect specimen, from which the restored outline (fig. 1) is taken, measures 2¾ inches in length, and 10 lines in its widest thoracic segment. All the somites are united ; and one of the swimming-feet, although injured, is still in place. The head, which is semicircular in outline, measures 4 lines in length by 9 lines in breadth ; the eyes are subcentral, and the occlli nearly central, as in the other species of Eurypterus. The first six segments (thoracic) succeeding the head measure together 9 lines in length; commencing with a breadth of 9 lines, they increase at the third segment to 10 lines, and diminish at the sixth segment to 7 lines in
