142 CANON A. M. NOKMAN ON 



2nd foot with the inner branch bearing a strong, curved spine-process and two long 

 setae. 



5th feet of nearly the same structure as those of the female, but very much shorter. 



This species was dredged, in company with Ancorabolus mirabilis, on the east side of 

 Little Cumbrae, in the Firth of Clyde, in 1888. Sars has found it in the outer part of 

 the Trondhjem Fiord and other places in Norway, and records a specimen taken by 

 Mr. Nordgaard at Repvaag in East Finmark. 



In my description of Ancorabolus I referred to this form as a second species of that 

 genus. I feel considerable difficulty with respect to the description I have given. In 

 its structural details it seems to agree closely with Sars's species, but in the drawing 

 which I publish it will be seen that the segments are armed with spines. These are 

 not noted by Sars. The drawing was made for me by Mr. A. Scott in 1890, who is 

 extremely accurate. In my specimens now mounted I am unable to see, in consequence 

 of the opacity of the animal, the spines referred to. I thought it was better, therefore, 

 to give it a varietal name, which can hereafter be used as specific if the form should 

 prove to be distinct from that described by Sars.
