30. E. fasciculatus, Harv. Caraquet Bay, Hay. 
31. E. bracliiatus, Harv. P. E. Island, Jeans- 
32. E (?) (A still undefined species). Shippegan Island, 
Hay. 
33. Elachistea fucicola, Fries. Pictou, MacKay; Halifax, Harvey; 
Frye’s Island, Miscou, Grand Manan, Hay. 
34. Leathesia difformis, (Linn.) Areschoug. Halifax, Harvey. 
35. Chordaria flagelliformis, Ag. Pictou, MacKay; Halifax, Harvey; 
Frye’s Island, Caraquet, Hay. 
36. Mesogloia divaricata, Kutz. Pictou, MacKay; Frye’s Island, 
Hay. 
37. M. vermicularis, Ag. Halifax, Harvey. 
38. Castagnea Zosterae (Molir.) Tliuret. Halifax, Harvey. 
39. Chorda filum, Linn. Pictou, MacKay ; Frye’s Island, Gulf Shore, 
Fowler, Hay. 
40. Laminaria longicruris, De la Pyl. Halifax, MacKay and Harvey. 
Stipes three or four yards long have been observed. Prof. 
Lawson, of Dalhousie College, says that on taking charge of 
chemistry on his arrival at Halifax he could get no rubber tubing 
in the city. While his order was coming he used the hollow 
stipes of this sea-weed, which is always cast up in abundance on 
the Halifax coast, and found it to answer splendidly for the con- 
duction of gas. — MacKay. A specimen of this plant thrown on 
the Caraquet beach measured seventeen feet in length, and the 
widest part of the blade from two to three feet wide. But in the 
masses of sea-weed thrown on the southern shores of Shippegan 
and Miscou still larger specimens were observed. One measured 
twenty-eight feet, while the stipe of another which was ail 
that could be pulled from the debris, measured fifteen feet. 
This species makes up the great portion of the laminarias grow- 
ing along the gulf shore of New Brunswick. It is distinguished 
by its hollow stipe. Around Grand Manan and the southern 
coast of New Brunswick the forms of laminariae are far more 
variable and confusing, the two following species (L. saccharina 
and L. digitata) being most abundant. —Hay. 
41. L. saccharina, (Linn.) Lam.x. ? Pictou, MacKay; Halifax, Prof. 
Lawson; Frye’s Island, Grand Manan, Hay; Gulf St. Lawrence, 
Fowler. 
42. L. digitata, Lam.x. Pictou, MacKay; Halifax, Harvey, Lawson ; 
Grand Manan, Hay. (The stipes of this species are used by 
surgical instrument makers in the manufacture of sponge- 
tents.) 
43. Saccorhiza dermatodea, De la Pyl. Halifax, Harvey ; Grand 
Manan, Hay.
