The MegalicMliys Jiibberti Ag., which this species resembles in some de- 

 gree, is represented by authors as having the scales minutely granulated 

 on the surface. The ganoine layer also covers the superior surface of the 

 skull, a peculiarity which is not present in the Ectosleorhachis nitidus.
