setae are rather more slender and the bifid papillae on the elytra rather 

 more deeply cleft.

This species, the type of which came from Icy Cape and is in the 

 collection of the Academy of Natural Sciences, appears to be quite 

 plentiful on the muddy bottoms of the Gulf of Georgia and equally so 

 on a gravelly bottom at Station 4228 in Behm Canal. Most of the 

 examples have lost most of the elytra and are otherwise mutilated, but 

 one specimen permits the description of the posterior elytra which were 

 lacking on the type. They are nearly circular in outline and of smaller 

 size and softer texture than the anterior elytra, but the most striking 

 difference is in the very great length of the terminal branches of the 

 dendritic spines of the posterior margin, the number of forkings of 

 which is, however, less than on anterior scales.
