scribed from New Zealand. I have no means of settling this 

 point, but the strong resemblance of the two plants from oppo- 

 site sides of the Pacific should be noted. 



Hildenbrandtia rosea, Kg. This species was first reported as 

 occurring in this country in Rept. U. S. Fish Comm. for 1 871. 

 The same plant under the name of //; sangiiinea appears to have 

 been previously reported by Mr. J. L. Russell in 1856, in Proc. 

 Essex Inst, i., 193, as occurring at Salem, Mass. H. sajtgninea, 



H. rubra and H. rosea are all referred by Hauck to H. prototypus, 

 Nardo. 



Choreocolax Polysiphonice, Reinsch, Plate LXXXVIII, fig. 3. 

 This species of the Atlantic shore of North America was de- 

 scribed and figured by Reinsch in Contrib, ad Algolog, et Fun- 



gblog. 



of Polysiphonia ft 



were collected at Nahant by Mrs. R. S. Eigenmann. On the 

 upper parts, especially at the dichotomies, were small hemispher- 

 ical masses of a brownish color and cartilaginous consistency and 

 hardly an eighth of an inch in diameter, which, on examination 

 appeared to be without doubt Reinsch 's species, although not 

 agreeing in all respects with his figure. As far as I am aware, 

 no fruit, either tetrasporic or cystocarpic, has previously been de- 

 scribed. The specimens from Nahant contained tetraspores. 

 The hemispherical external part of the frond consists of a mass 

 of filaments composed of purple colored cells which branch and 

 radiate to the surface, where they end in pyriform cells encased in 

 a dense mass of jelly. The tetraspores are formed from the ter- 

 minal cells and are usually cruciate, but not rarely tetrahedral. 



Fiicus edentatus, De la Pylaie. The F. furcatiis of Marine 

 Alga; of New England is without doubt the same as F. edentatus 

 of Newfoundland, formerly united with F. fnrcatus, Ag., of the 

 North Pacific, a species to which was also referred a Fucus of the 

 northern coast of Norway. Later the two species were kept dis- 

 tmct by Prof J. G. Agardh, and Kjellman in the Algs of the 

 Arctic Sea referred the so-called F. furcatus of Norway and
