* Since described under the name, Asterias Atlantica Verrill, from Brazil, Cuba, and 

 Bermuda, — Reprint. 



f Mr. A. Agassiz records 19 additional species, including 9 new genera and 14 new 

 species, from the deep-sea coUeetious of Pourtales, in Bulletin M. C. Z., No. 9, — Reprint. 



\ The Essex Institute, Salem, Mass., has two specimens, beautifully variegated with 

 green, and agreeing entirely with the description of this species. One is labelled as 

 coming from the "West Coast of Africa," the other from the "Sandwich Islands." 

 The former locality is most likely to prove to be the true one.
