Pal/lopecten Danbyi McCoy. 
Remarks. — As Williams* lias recently pointed out, it is 
probable that more than one species has been included by 
McCoy amongst the shells from Westmoreland, which were 
named by him Avicula Danbyi. In the Usk district also the 
species may likewise be composite. The genus Palceopecten has 
been established by Williams {op. cit) for this type of shell, and 
the British representatives must be revised in the light of his 
conclusions. 
Horizon and Localities. — Ludlow beds : (i) in Usk Station 
Cutting ; (2) behind Parish Room, close to Llanbadoc Church ; 
(3) in the quarry close to Ffynnonau, near Clytha Castle ; 
(4) in the quarry 500 yards South of Clytha Castle ; (5) in the 
quarry by the side of the road leading East from Sluvad, about 
half a mile from the farm of that name ; (6) in Sorbrook, half 
a mile North-East of Llanthewy Court ; and (7) in the quarry 
to South-West of the Farmers' Arms, Llandegveth. 
Eurymyella cf. Shaleri Williams [PI. VIII., fig. 3.] 
Remarks. — The reasons for the separation of the genus 
Eurymyella from Modiolopsis Eurymya, Anodontopsis and 
Whiteavesia have been carefully explained by the author of 
the genus, H. S. Williams,^ and following his definition, 
there is a shell from Usk, which . must be referred to it, 
and it agrees closely with one of his species, E. Shaleri 
Williams,^ occurring in the Cobscook Bay Series (Silurian) 
of Moose Island, Maine. Williams remarks on the resem- 
blance of this species to the British Anodontopsis angustifrons 
McCoy'^, from the Upper Ludlow of Kendal ; but our Usk 
right valve cannot be referred to A . angustifrons, as it has no 
posterior lateral teeth. 
Dimensions. — Length, 11.5%. 
Horizon and Locality. — Near the topofWenlock Shales by 
the road-side above Upper Wern-hir.
