170 DR. HARVEY ON A COLLECTION OF ALGE 
42. Delesseria hypoglossum, var. arborescens, Lamour.; D. arborescens, 
De la Pyl. 
Fuca Strait, Dr. Lyall. 
Fine specimens, not unlike some from the North of Ireland, or 
the * D. arborescens ” of the French coast. 
43. Delesseria alata, Lamour., var. latissima. 
On stems of Nereocystis, Dr. Lyall. 
The fronds, though evidéntly not fully developed, are of extraor- 
dinary width ; the broadest 1—3 inch, the narrower 1 inch wide. 
44. Hymenena fimbriata, P. & R.; Harv. Ner. Bor. Amer. ii. p. 102. 
On the beach, Victoria Harbour; Esquimalt, Dr. Lyall & C. Wood. 
45. HYMENENA LATISSIMA, n.s. Fronde latissima, juniore flabelli- 
formi, adulta vage partita v. laciniata infra venulosa sursum subavenia, 
laciniis latissime cuneatis v. flabellatis inciso-lobatis, lobulis rotun- 
datis, cystocarpiis sparsis, soris totam frondem demum percurrentibus. 
Esquimalt Harbour, dredged and adrift, Dr. Lyall, C. Wood. 
Fronds 12-15 inches long and wide, variously cleft, the seg- 
ments fan-shaped, cut at the apex into many, short, round-topped 
lobes. The lower half of the frond is traversed with many con- 
spicuous, subparallel, anastomosing veins; the upper apparently 
nerveless, until the tetrasporic fruit is formed, when the inter- 
spaces of the sori indicate the lines of nervation ; and in older 
specimens anastomosing nerves may be clearly traced, even to the 
extremities. Colour, a bright red. The herbarium contains spe- 
cimens with both kinds of fruit; but the bulk of those sent are 
without fructification, and consequently not clearly distinguish- 
able from a Nitophyllum. 
46. Nitophylli? v. Hymenense species ? 
Victoria Harbour, in deep water, Dr. Lyall. 
Specimens without fruit, much torn, and proliferous from the 
wounds, and therefore not determinable. Some look as if they 
belonged to Nitophyllum laceratum, and others like a divaricated 
state of Hymenena. 
47. Gracilaria confervoides, Grev. ; Harv. Ner. Bor. Amer. ii. p. 108. 
Esquimalt, Dr. Lyall. 
A deep-water variety, very much resembling, in ramification 
and aspects, our Cystoclonium gracilarioides, but quite distinct in 
structure. 
48. Rhabdonia Coulteri, Harv. Ner. Bor. Amer. ii. p. 154, t. 23. B. 
Esquimalt, C. B. Wood. 
A single specimen, in fruit (cystocarpia).
