476 PROCEEDINGS OP THE AMERICAN ACADEMY 



scopic examination when they were soaked out for preparation showed 

 that the measurements agreed with those of Porphtjra miniata. 



FUCACEiE. 



A few specimens of Fucus were collected at Ungava Bay, but they 

 were all sterile and otherwise in too unsatisfactory condition to be 

 determined. 



PH^OSPORE^. 

 Laminaria longicruris, De la Pyl. 

 A single small specimen from Ungava Bay, with a fragment of 

 another unrecognizable species of the genus, and an imperfect Alaria. 



Agarum Turneri, Post. & Rupi\ 

 Ungava Bay. Several rough-dried specimens. 



Chorda filum, Stackh. 

 Ungava Bay (Turner, no. 485). 



Desmarestia aculeata, Lamour. 

 Ungava Bay (Turner, no. 507, 535, 4870, and 4872). 



Chordaria flagelliformis, Mull. 

 Ungava Bay (Turner, no. 500 and 4870), also collected by the 

 Howgate Expedition. 



Ralfsia deusta, J. G. Ag. 

 Ungava Bay. A single fine specimen four inches in diameter. 



DiCTYOsiPHON f^niculaceus, Grev. 



DiCTYOSiPHON f^niculaceus, Grev., var. flaccidus, Aresch. 



DiCTYOSiPHON HippuROiDES, Aresch. ? 

 The species of Dlctyosiphon are, at the best, difficult of determina- 

 tion, and of the material collected at Ungava Bay it is impossible to 

 speak with certainty, except that some of the few specimens may un- 

 doubtedly be named D. foeniculaceus. No. 464 is probably the vari- 

 ety ^aeciW?<s, and no. 475 may be referred with considerable doubt to 

 D. hippuroides. Without a larger set of specimens, one could not 

 venture to feel sure of the determination. 



Phlceospora tortilis, Aresch. 

 Kikkerton Islands. Growing on small stones, July, 1878. Abun- 

 dant (Kumlien). This is an interesting addition to our Arctic flora.
