 numbers five species, including that alluded to, but not de- 

 scribed, by Mertens.

of Chili and Behring Strait as the home of this to Beroe (Mertensia) compressa, which is truly an 



species, I suspect, that, in the arrangement of his arctic species ; for it is hardly credible that the same 



manuscript, which was printed after his death, the species should occur in the waters of Behring 



editor may have confounded the memoranda relating Strait and on the coast of Chili.
