174 DR. HARVEY ON A COLLECTION OF ALGE 
longis, 3-5 lineas latis, plus minus margine pinnulatis, pinnulis sub- 
horizontalibus anguste linearibus v. apice dilatatis. 
This seems to be the central or typical form of the species. The 
larger fronds are 12-14 inches in the expansion of the branches. 
Var. ò. densissima. Fronde creberrime ramosissima pluries pinnatim 
ramosa, pinnis pinnulisque linearibus basi angustatis. 
A narrower and more densely branched state than the preceding. 
Var. e. intermedia. Fronde ramosissima angustata, ramis superioribus 
plus minus dilatatis. 
Between 6 & £Z. 
Var. €. dilatata. Fronde plus minus ramosa vix pinnulata, ramis supe- 
rioribus dilatatis foliaceisve lanceolatis. 
Var. 5. depauperata. Parvula, debilis, szepius di-pollachotoma et fasti- 
giata. 
Numerous other minor and connecting states might be named. 
71. PRIONITIS LANCEOLATA ? var. FILICINA. Fronde creberrime bi- 
tripinnata, pinnis pinnulisque horizontalibus. 
On rocks, Esquimalt, Dr. Lyall. 
Two specimens only. In substance, colour, and structure these 
specimens agree with the Californian P. lanceolata, than which, 
however, they are much more densely branched and more pinnated. 
I do not venture to propose them as specifically different. 
72. Schizymenia Dubyi, J. Ag.; Harv. Ph. Br. t. 123. 
On rounded pebbles, on an exposed beach, Esquimalt, Dr. Lyall. 
Very similar to some of the larger English specimens. 
73. Schizymenia Mertensiana, P. & R.? J. Ag. Sp. ii. p. 174. 
Adrift, Victoria Harbour, Dr. Lyall. 
A fragment only. The substance resembles parchment. 
74. SCHIZYMENIA ? COCCINEA, n.sp. Fronde.................. maxima 
rubro-coccinea gelatinoso-membranacea tenui, siccitate charts arcte 
adh:zrente, structura laxa, filis medullaribus paucis arachnoideis. 
Dredged in 14 fathoms, Griffin Bay, St. Juan Island, Dr. Lyall. 
Fragments only, from which the outline can be but vaguely 
guessed at. The largest piece is about 16 inches long and a foot 
wide, and presents a bright-crimson, glossy, soft membrane closely 
adherent to paper. Its cellular structure is rather that of Haly- 
menia; but the habit is more that of Schizymenia, where I pro- 
visionally place it. 
75. Gloiosiphonia capillaris, Carm.; Harv. Phyc. Bor. t. 57. 
On stems of Nereocystis, Dr. Lyall. 
Two specimens only.
