Remarls. — Muller and Troschel's description of Fchinaster eschrichtii agrees in 

 tlie main with this coinraon siiore form of Bering Sea. AUliough there are no 

 records between Point Franklin and Greenland (which is not surprising), I l>elieve 

 I do not err in applying tiie name eschrichtii to the species under consideration. It 

 hixs seemed di>sira})le to keep this siiort-rayed, thick-set form with conspicuous 

 marginal plates tlistinct from typical sanguinohnia. Wliether it is a distinct 

 species with a distrihiition nearly coextensive with saiiguinolenta or only a variety 

 of the latter, must for the present remain undecided. I have, however, founti 

 several intcrgrades, ami for that rcn.son and the obviously close kinship of ischrichtii 

 to sangninolenta have used a trinomial designation.
