Soc." vol. i. (1870), p. 292. Enlarged scales figured, ibid. 

 Plate XII. Fig. 6. Turin Hill. 



Euthaeanthus eurtus, Powrie. — Imperfect fish, from Farnell, 

 described and figured by Powrie, ibid. p. 293, Plate XII. Fig. 7. 



Note. — Messrs. Smith Woodward and Sherborn, in their " Catalogue 

 of British Fossil Vertebrata," p. 65, have placed this species 

 in Diplacanthus with a query. A second specimen in the 

 collection from Turin Hill shows, however, that there were 

 more than one pair of intermediate ventral spines, so I have 

 kept it here for the present, although its general contour is 

 somewhat unlike that of the other members of the genus.
