Cope, is identical with his Peplorhina anthracina. The chief dis- 

 tinction made by him : the ditference in the surfaces of what he 

 calls the " gular shields" in one case smooth, in the other granu- 

 lated or pustular is due simply to the exposure, in one case, of 

 the inside, and the other, the external and ornamented surface of 

 the cheek plates as the^'^ are, and not jugulars as he considers 

 them. 



6th. The material representing Prof. Cope's genus Peplorhina 

 is too imperfect for satisfactory study, but, in my judgment, it 

 represents an amphibian and not a fish. 



I ought, perhaps, to say in justification of the somewhat posi- 

 tive manner in which tlie above statements are made, that they 

 are based upon a careful study of an immense amount of material 

 which I have been gathering from Linton during the last twenty 

 years. The richness of this material may be inferred when I say 

 that of the species especially referred to in the above note, Ccela- 

 canthus elegans, I have obtained more than 500 specimens.
