A form of Eurylepis, apparently distinguished from E. granulata 

 merely by the extension of the scale-ornament over the caudal 

 region, is named E. ornatissima, J. S. Newberry, Rep. Geol. Surv. 

 Ohio, vol. i. pt. ii. (1873), p. 352, pi. xxxix. fig. 4 (= J\£ ecolepis 

 oniatissimus, J. S. Newberry, Proc. Acad. Nat. Sci. Philad. vol. viii. 

 1856, p. 97). Three other species are also determined as enume- 

 rated below, the type specimens being nearly complete fishes in 

 the Aluseum of Columbia College, New York : — 



Eurylepis corrugata, J. S. Newberry, Rep. Geol. Surv. Ohio, 

 vol. i. pt. ii. (1873), p. 350, pi. xxxviii. fig. 4 : Mecolepis 

 oorrugatus, J. S. Newberry, Proc. Acad. Nat. Sci. Philad. 

 vol. viii. 1856, p. 96 (adopted as type of Mecolepis). 



Eurylepis (?) lineata, J. S. Newberry, ibid. 1873, p. 353, pi. 

 xxxix. fig. 7 : Mecolepis lineatus, J. S. Newberry, ibid. 

 1856, p. 97 : Bhadinichthys (?) lineatus, J. S. Newberry, 

 Palseoz. Pishes N. America (Mon. U. S. Geol. Surv. no. xvi. 

 1889), p. 228. 



Eurylepis striolata, J. S. Newberry, torn. cit. 1873, p. 355. 



The small fish from the Coal-Measures of Linton, Ohio, named 

 Mecolepis serratus, J. S. Newberry (Proc. Acad. Nat. Sci. Philad. 

 vol. viii. 1856, p. 97), does not appear to have been mentioned 

 since the original notice. 



The following specimens appear to the present writer to be 

 specifically indeterminable immature individuals : — 



P. 998. Two small fishes of the form named Eurylepis ovoidea \ 

 from Linton. Egerton Coll. 



P. 1006. Three small fishes of the form named Eurylepis minima 2 , 

 from Linton. Egerton Coll. 



P. 3451. Four similar specimens. EnnisJcillen Coll. 



Another genus of stout proportions, with nearly vertical sus- 

 pensorium, now assigned to the Paheoniscidoe, is Benedenichthys, 

 R. H. Traquair (Ami. Mag. Nat. Hist. [6] vol. vi. 1890, p. 492), 

 originally defined under the pre-occupied name of Benedenius 

 (Traquair, in L. G. de Koninck, Paune Calc. Carb. Belg. pt. i. 1878,
