1. — Pteryyotus of the Upper Llandovery Sandstone. 



Having been requested by my friend Mr. Henry Woodward, of the British Museum, 

 to give a short description of the principal localities in which those remarkable Crustacea, 

 the Pteryyoti, Stylonuri, and JEurypteri, are found in the region of Siluria, I cannot do 

 better than allude, in the first place, to the oldest known form of Pteryyotus, discovered 

 some years ago by Mr.John Burrow, of Great Malvern, and figured in the ' Memoirs 

 of Hugh Edwin Strickland,' by Sir Wm. Jardine, Bart., under the title of " Pteryyotus 

 pi'oblematicus." It is the jaw-foot only that is preserved. The strata in which the 

 relic was discovered belong to the upper series of the Upper Llandovery beds, where 

 they support the Obelisk in Eastnor Park, near Ledbury, Herefordshire. The common 

 fossils of these strata are the Nucula Eastnori, with Pentameri and Stricklandinia. The 

 author of these notes was present with the Malvern Field Club when this oldest known 

 evidence of the existence of Pteryyotus was discovered. 



2. — Wenlock Limestone and Shale. 



Although I am tolerably conversant with the fossils as well as the physical geology of 

 the Wenlock rock series, it was not until lately that I became acquainted with the fact 

 that remains of Pteryyotus had been found therein. Mr. Woodward, however, has 

 directed my attention to the occurrence of portions of the body of this Crustacean in a 

 slab of Dudley Limestone in the British Museum. The rock in which these relics occur is 

 undoubtedly the well-known Wenlock Limestone, so celebrated for its Trilobites and 

 Crinoids. The remains occur not only imprinted upon shale attached to the limestone, 

 but, in several instances, in the limestone itself. 



The first of these remains, consisting of small fragments only, covered with the cha- 

 racteristic scale-markings, were obtained by Mr. John Gray, of Hagley, and are now in 

 the British Museum.
