limestone of Scotland, equivalent in age to the Mississippic of North 

 America, has yielded three species of Eurypterus: scabrosus, Wood- 

 ward, scouleri Hibbert and ? stevensoni Ethridge. Of the first species 

 a doubtful fragment has been reported from Eskdale, Scotland. 

 Hibbert was the first to describe as a Eurypterus the two nearly com- 

 plete individuals and three or four fragments found in the Burdie- 

 house fresh-water limestone at Kirkton, near Bathgate, West Lothian. 

 The organic remains are scattered through in no regular order and 

 are not confined to the limestone particularly, but occur in the sandy 

 beds above and below, not in particular seams. One of the euryp- 

 terid remains had earlier been described under the name Eidothea, 

 but Hibbert rightfully called it Eurypterus scouleri (116, 280, 281, 

 pi. XII). Vegetal matter is diffused through the limestone and in 

 this fossil plants are well preserved, the form particularly abundant 

 being Sphenopteris affinis. Microscopic Entomostraca abound which 

 have been named by Hibbert Cypris scoto-burdigalensis , and a micro- 

 scopic mollusc approaching Planorbis also occurs. Fish remains are 

 abundant: Gyracanthus formosus Agassiz, ganoid and sauroid teeth, 

 and many coprolites are found. Woodward says of this limestone: 

 "it is a fresh water deposit, and abounds in bands of silex alternating 

 with calcareous matter and presents all the appearance of having been 

 deposited by thermal waters during the Carboniferous epoch" (312, 

 1 8a). The third species above referred to was described by Etheridge 

 from a few fragmentary spines found in a light-colored micaceous 

 sandstone of the Cement-stone group in Kimmerghame quarry, near 

 Dunse in Berwickshire, Scotland. In the same shire Peach has 

 recently discovered some fragments for which he erected the genus 

 Glyptoscorpius, a eurypterid which had combs, and walking feet 

 ending in two claws. In the Calciferous sandstone here at Lennel 

 Braes, near Coldstream, Berwickshire, a specimen of G. perornatus 

 Peach showing five body segments much broken, and a number of 

 combs, referred to G. caledonicus (Salter) have been found. Besides 

 these, are a number of fragments referred to the genus Glyptoscorpius, 

 but specifically unidentifiable (209, 516-525). At the River Esk, 

 four miles south of Langholm, Dumfriesshire, the two species of 

 Glyptoscorpius are found with the foil owing associates: several species 

 of Phyllocarida, Ceratiocaris scorpioides Peach, C. elongatus Peach; 

 Peracarida, Anthrapalaemon etheridgei Peach, A. parki Peach, A. 

 traquairii Peach, A. macconochii, A. formosus Peach, Palaeocrangon 

 eskdalensis Peach, Palaeocaris scoticus Peach, and later discoveries
