nis, Thuret. This common European species, 

 recognized by the moncecious conceptacles and margined recep- 

 tacles, has only recently been recognized with certainty on our 

 eastern coast. It appears to be not uncommon at Nahant, 

 Mass., and is In good fruit in October. 



rntea, Aresch. A second species o{ Nereocystis 

 from the coast of California was described by Areschoug in Bot. 

 Notiser, 1876, p. 71, which in Bot. Notiser, 188 1, p. 49, was made 

 the type of a new genus, Pelagophycus. The two species of 

 Nereocystis are certainly distinct, but in my own opinion they 

 form one very natural genus from which Pelagophycus cannot be 

 separated generically. The specimens described by Areschoug 



were collected near San Francisco by Dr. Eisen, and the same 

 plant has been occasionally seen by Dr. Anderson at Santa Cruz, 

 but, strange to say, the locality where it most abounds is much 

 farther to the south, at Pt. Loma, near San Diego, Cal., and ex- 

 tending to Todas Santos Bay, in Lower California, where it was 

 found by Mr. Orcutt and Mrs. Eigenmann. Near San Diego, 

 according to Mr. D. Cleveland, it appears to be the only Nereo- 

 cystis which occurs, certainly in any quantity. It is difficult dry- 

 ing specimens of this very succulent plant, and even in a cHmate 

 as dry as that of California, it usually rots without drying, but, 

 in the hotter air, of Lower California, according to Mrs. Eigen- 

 mann, it is often found dried on the beach and the bladders are 

 used for making a rough sort of lamp. N. gigantea differs from 

 N. Liitkeana in having the fronds above the bladder, borne not 

 on short pedicels, but on dichotomous stipes several inches long. 

 Whether the ciliate margins are also specific is less certain, for,
