 of these nodules, which appear to 

 contain the skeletons of some spe-

 that I have been unable to identify 

 the species. Recently, Mr. J. 

 Stewart, of Ottawa, has kindly 

 placed in my hands a better pre- 

 served specimen, showing more 

 especially the pre-opercular spines 



and pectoral fins in comparatively 

 good preservation, and with the 

 help of these I think I can identify 

 the species, notwithstanding the 

 confusion which at present seems 

 to reign as to our North American 

 cottoids.

 spines and of the pectoral fin seem 

 to identify this specimen with Cottus 

 {Oeiitrodermichthys) undnatus of 

 Gunther's British Museum cata- 

 logue. This is C. undnatus of Rein-
