 No. 2 in non-calcareous black shale. No. 3, two separate left valves. These have no fringe on 

 the ventral border, but the edge is turned up as a sharp rim along its front half. In very slightly 

 calcareous black shale. Nos. 4 and 5 in black shale slightly calcareous. No. 5 is a left valve, 

 together with the filmy relic of another similar valve, with a narrow fringe and very fine mesolateral (?) 

 ridge. No. 7 a right valve, badly preserved as a light brown film. No. 8 (PI. XXV, fig. 2) has a 

 delicate fringe, continued forward into the simple raised ridge. Mus. Geol. Surv. Scotl., No. 25, is 

 from " the shore east of Ardross Castle, Elie." In the British Museum there is a group of fifteen 

 loose pieces of black shale with fragments of D. glabra, of which seven are from Ardross and eight 

 from Castle Ardross. 



" There are two places at Ardross where fossils are found. One is a little west of the remains 

 of the old castle, and the other about a hundred yards east of it. The latter place is where 

 Ditht/rocaris and other crustaceans are met with. 'Ardross' and 'Ardross Castle' are used 

 indift'erently for either or both spots. Ardross itself is a farmhouse, and nearest to the Bithyrocaris 

 locality. There is no village called Ardross. Elie is about a mile to the west, and is the nearest 

 post-town and railway-station." — J. "\V. Kiekbv, July Sth, 1898.
