are elongate, with anterior and posterior cutting edges, and are 

 recurved. Their size seems to diminish very suddenly toward 

 the posterior extremity, which is expanded. The epi-, cerato- 

 and urohyals are in place on one side but do not seem to differ 

 materially from those described above. A portion of the pec- 

 toral fin shows the rays to be cross-segmented as in E. nepse- 

 olica, but the proximal ends are straighter than in this form. 

 The bones are for the most part in so fragmentary a condition 

 that only approximate measurements can be made ; hence they 

 are omitted. 



OSTEOGLOSSID^E 



The genus Anogmius j described by Professor Cope, 94 was left 

 by the author in his family Stratodontidtc, to which, it seems evi- 

 dent, it does not belong. 



After carefully studying the material at hand, it seems to bear 



a close relation in many respects to the genus Plethodus, recently 



described and figured by Dr. A. S. Woodward, 96 which the 



author is inclined to place in the family Osteoglossidse. For the 



present, at least, I think that Anogmius should be left in this 



family. 



ANOGMIUS. 



Cope, Proc. Am. Phil. Soc. 1870, p. 170. 



This genus was first described by Professor Cope 95 from ver- 

 tebrae and fin remains of an individual from the Niobrara Cre- 

 taceous of western Kansas ; the name Anogmius contractus was 

 applied to it, and, later, two more species, 97 A. favirostris and 

 A. evolutus, were added to the genus by the same author. The 

 first of these was a small individual, while the second was much 

 larger, and is probably the same form described as ? Beryx multi- 

 dentatus,™ described by myself. Professor Cope also mentions 

 another species, A. aratus, but so far I have been unable to find 

 any other reference to it. I am inclined to think that this was 

 a slip of the pen on the part of Professor Cope, and that A. con-
