594 THE FUR SEALS OF THE PRIBILOP ISLANDS. 



Ptilota asplenioldes (Turn.) Ag. No. 82. Faiiow, Anderson, and Eaton, Alg. Exsicc. Am. Bor., No. 82. 

 Kjellman, Beringsliafvets Algflora; 32, 1889. 



Plumaria asplenioides Evipr., Tange Och. ; 232, 1851. 



This largest, coarsest, and deepest- colored species of all the genus occurs in all 

 the collections from St. Paul and is further credited to it by Ruprecht. It must be 

 abundant along its shores and constitute its most characteristic species. (Bering 

 Island.) 



ptilota peotlnata (Gunn.) Kjellm. Kjellman, Berlngshafvets Algflora; 32, 1889. 



Specimens of this species occur in the collection made for Prof. D. 0. Eaton by the 

 Alaska Commercial Company in 1877. (St. Lawrence Island.) 



Ptilota illicina (Eupr.) J. Ag. 



A few specimens of what seems to be this species occur both in the collections of 

 the Albatross and those received from President Jordan. It is not always easy to 

 tell this species from P. plumosa or P. serrata. 



Odonthalia kamtschatioa (Rupr.) J. Ag. Kjellman, Berlngshafvets Algflora; 23, 1889. 

 Atomaria Tcamtschatica Rupr., Tange Och. ; 214, 232, 1851. 



Known to occur at St. Paul only through the reference in Ruprecht. 

 Rhodomela floccoaa (Esp.) Ag. Kjellmann, Berlngshafvets Algflora; 24, 1889. 



The forms referred to this species from St. Paul are by no means near the type of 

 the species. They are very much more slender than the ordinary Californian form, 

 resembling B. lycopodioides in this respect, but approaching B. larix in others, so that 

 the species as now understood and ranging from San Diego to Bering Island presents 

 an infinite variety of forms as regards coarseness or fineness and even as regards the 

 flattening of its branches, the character upon which its claim to specific rank princi- 

 pally rests. (Bering Island.) 



Rhodomela larix (Turn.) Ag. Kjellman, Berlngshafvets Algflora; 24, 1889. 

 Fuacaria larix Ruprecht, Tange Och. ; 219, 1851. 



Known from St. Paul only through this reference of Rupreoht's. (St. Lawrence 

 Island and Port Clarence.) 



Nitophyllum ruprechtianum J . Ag. ? 



Two more or less imperfect specimens of a large Nitophyllum of the Botryoglossum 



section, but provided with neither cystocarps nor sori, probably belong here. In the 



absence of any kind of reproductive bodies, however, it is impossible to tell with 



certainty. They were collected by Messrs. Greeley and Snodgrass. 



Nitophyllum ruthenicum (P. and R.) Kjellm. Kjellman, Berlngshafvets Algflora; 25 PI I f 11 

 12, 1889. ' ■ ' 



The specimens referred to this species were seen in Herb. Parlow at Harvard 

 University and were collected at St. Paul Island by Mr. White. They are young and 

 more or less incomplete plants; consequently they do not show the habit very well. 

 This is, however, quite variable, judging from Kjellman's figures (1. c). The speci- 

 mens of Mr. White are tetrasporic and have microscopic veins, at least at the base. 

 With the exception of the veins, they resemble very closely N. spectabile D. C. Eaton, 

 of the Californian coast. (Bering Island.) 



Delesaeria crassifolia Rupr. Ruprecht, Tange Och. ; 232, 18151. Farlow, Proc. Amer. Acad 21-473 

 1886. ' ' 



D. crassifolia is a large and apparently characteristic species of the Pribilof
