the preparation of this paper. Professor Setchell says, 

 "Specimens in herbarium of Professor Farlow (ex. herb. 

 Acad. Petrop.) labelled '■ Aglaofhylhun rutkenicum, Exp. 

 Lutk. ad litora Americanas borealis-occidentalis, Ross' are 

 young (about an inch high, with no fruit present), and 

 might be the young plants of JV. s-pectabile. In the herba- 

 rium of Farlow are also several specimens from St, Paul 

 Islands, in Behring Sea (legit White), which might be N. 

 sfectabihy 



The account of this species was advanced to a great 

 extent by examination of a large collection of material from 

 Mrs. J. M. Weeks, of Santa Cruz, Calif., who made an 

 especial effort to secure antheridial, tetrasporic, and cysto- 

 carpic plants. The material thus obtained confirms the 

 conclusion that N. spectabile is entitled to rank as a distinct 

 species, as established by Professor D. C. Eaton.

 zone. Dredged in 12-15 fathoms, Monterey Bay, Calif.
