THE skull here described is that of Anarrhichthys ocellatits, 

 or wolf-eel. The AnarThichadidas proper are found in the 

 northern waters, few coming farther south than the 

 fiftieth parallel, and indeed most of them are found within the 

 Arctic circle. The subfamily Anarrhichthys is found farther 

 south, and the species described was taken at Monterey Bay, 

 California.
