182 GANOID FISHES OF THE CARBONIFEROUS FORMATION. 



Genus — Eurylepis, Neioherry, 1857. 



1. EuBYLEPis ANGLICA, Traquair.

pi. ix, fig. 9. 



Description. — This is the posterior part of a cranial shield, representing the fused 

 parietals, frontals, and squamosals ; it is |- inch in length and the same in breadth across 

 the parietal region. It is ornamented with tolerably coarse rounded ridges, which are 

 comparatively slightly elevated and mainly follow a direction concentric with the margins 

 of the respective bones, except at the anterior angle of each frontal, where there is a 

 group of ridges, which pass obliquely inwards and a little backwards, so as in the 

 middle line to meet those of the opposite side at an obtuse angle. 



.Observations. — This little relic is almost identical with the similar cranial shield of 

 Burylepis tuberculata, Newberry,^ from the Coal Measures of Linton, Ohio, but differs in 

 the ornament being more of a ridged than tuberculated character. 



Messrs. Hancock and Atthey mention, without description, the occurrence of a fish 

 in the Northumberland coal-field which they suspected might belong to Newberry's 

 Eurylepis ; but there cannot be any doubt of the generic position of this, the first 

 figured English specimen. 



Geological Position and Locality. — From the Ash Coal-shale (Upper Carboniferous), 

 Longton, Staffordshire. Collected by Mr. J. Ward, F.G.S., by whom it was lent to me 

 for description. The specimen is now in the British Museum. 



Genus — Styeacopterus, Traquair, 1890. 



A genus closely related to Benedenichthys, Traquair, from the Carboniferous Limestone 

 of Belgium {Benedenius, Traquair, in de Koninck's * Faune du Calcaire carbonifere de 

 la Belgique,' pt. i, 1878, p. 15). 



1. Styracopterus fulcratus, Traquair.
