as to this, 17 are males, 28 females. Among specimens obtained at Petro- 

 jiaulski and at Albaiross Station 3646, off Kobben Island, in 18 fathom-, 

 no males are included. TLe females differ from those we have examined 

 from Bristol Bay in having the top of head more extensively plated, the 

 rough plates extending onto middle of iuterorbital space, or in 1 specimen 

 onto snout. The preorbital ridges are less regular and have lower tuber- 

 cles. The specimens indicate an approach therefore to 6r. galeatus. The 

 fin rays are as previously given. In 8 specimens they are as follows:

•'Mr. Scofield has the following note on this species:

Fin formula'. 



I have compared them with .specimens taken by the Albatross in southern Bering Sea 

 and find them the same. In tlii' female taken at Port Clarence the crown (not between 

 the eyes), nape, and ujiper half of opercles are covered with scabrous bony plates. These 

 plates are present in souie of the females taken by the Albatross, but are not so evident. 

 The female has a few scattered iiiui;h jirickle.s back of the origin of the pectorals. The 

 males have the mueliroiiiu like tiliuiuiits <ci\ cn-d by the pectorals, and the middle rays of 

 the pectorals have ]>a]iiUir iilmi-j; their iuuer edge. Tliis fish has been reported from the 

 Atlantic side of North Auurica, Imt it is probably a ditierent species, as the mushroom- 

 like filaments are not mentioned in their desciiption. Sir John Richardson took a single 

 specimen, a female 5 or 6 inches long, at Hudson Bay, which appears to be the same as 

 these from Bering Sea. He identified it as Fhobetor tricrispis (Kroyer), and his plate of it 

 agrees perfectly with our specimens, but in his description he does not mention the prickles 

 back of the origin of the pectorals, and he mentions a few scabrouabony plates just below 

 the second dorsal which our specimens do not have.
