119. Dinichthys terrelli Newberry. Cleveland shale; north- 

 ern Ohio. 



The most recent restoration of the skeletal parts of this spe- 

 cies is that given by Professor E. B. Branson, of Oberlin Col- 

 lege, in volume <S of the Ohio Naturalist (1908), pp. 365, 367, figs. 

 1,2. 



120. Dinichthys intermedins Newberry. Cleveland shale; 

 northern Ohio. 



121. Dinichthys minor Newberry. Cleveland shale; north- 

 ern Ohio. 



122. Dinichthys curtus Newberry. Cleveland shale; north- 

 ern Ohio. Also according to Newberry's identification, from 

 the Chemung of Warren, Pennsylvania. 



123. Dinichthys gouldi Newberry. Cleveland shale; Berea, 

 Ohio. The so-called D. prentis-clarhi of Claypole is very likely 

 identical with this species. 



124. Dinichthys clarhi Claypole. Cleveland shale; Berea, 

 Ohio. The type of this species was originally described under 

 the name of "Gorgonichthys" clarhi, but is not generically dis- 

 tinct from Dinichthys. The obscure dental plate subsequently 

 described as D. clarhi is of different nature, and requires a new 

 specific title if retained in the genus Dinichthys.* 



125. Dinichthys gracilis Claypole. Cleveland shale; Berea, 

 Ohio. 



[Dinichthys hepleri and D. prentis-clarhi Claypole. These are 

 probably synonymous with D. herzeri Newberry and D. gouldi 

 Newberry respectively. Both are from the Cleveland shale of 

 the Eocky river valley, Ohio.] 



126. Brontichthys clarhi Claypole. Cleveland shale; Cuya- 

 hoga county, Ohio. 



127. Stenognathus corrugatus (Newberry). Cleveland shale; 

 Lorain county, Ohio. 



128. Titanichthys agassisii Newberry. Cleveland shale; 

 Lorain county, Ohio. 



129. Titanichthys attenuatus Wright. Cleveland shale; 

 Ohio. 



130. Titanichthys brevis Claypole. Cleveland shale; Ohio.
