Two specimens from station 4281, one from 4285, one from 4286 (all in Chignik Bay), and one from

 Bristol Bay (Gilbert 1895). 



This species is easily distinguished by the 2 pairs of spines on occiput, but the specimens we have 

 vary as to the number of dorsal spines, there being 8 or 9, and the rays vary from 17 to 20.
