Liebmannia (?) but without specific name, and some 60 species of 
desmids are figured on Plates XLIII and XLIV. 
Nereocystis Priapus (Gmelin) Saunders takes the place of JV. Luet- 
&eanus Mert, universally accepted since its publication in 1829. 
While it is probable that Gmelin's plate of Ulva priapus, published 
in 1768, represents a fragment of a frond of this species, no one 
before Mr. Saunders has proposed the change, though Gmelin's 
name has often been mentioned as a possible synonym. 
Some curious phrases occur: p. 426, Alaria lanceolata is said to 
be “easily recognized by the tufts of long cryptostomata "; p. 434, 
Jridea membranacea J. Ag., “To this species Dr. Farlow has very 
questionably referred," etc. The context shows that * questionably ” 
is used in the sense of ** doubtfully," and the word is used in apparently 
the same sense (p. 440) in regard to G/orosipAonia californica. On 
p. 438 there are notes on the “ perithecia " of two species of Odon- 
thalia. There is a curious tendency to give specific names the femi- 
nine ending in all genera whose names end ina. In the table, p. 394. 
this is consistently carried out, — Streblonema pacifica, Homeostroma 
undulata, etc. In the descriptive text, later, some are changed to 
neuter, others continue feminine. Possibly these are only instances 
of the misprints which abound in the names throughout the paper, 
due in part to scanty time allowed for correction of proof, and per- 
haps to volunteered corrections by sóme other than the author. See 
P- 414, Cladophora arctica for C. arcta. 
The plates are clearly drawn and printed, the descriptions of new 
species are fairly complete, and, as a whole, the paper is a valuable 
addition to our knowledge of the plants of our northwestern 
possessions. 
Agardh's Alga.'—— In the notice of Part III of this work, in the 
American Naturalist for June, 1899, attention was called to the long 
time, the greater part of the nineteenth century, of Agardh's work in 
this field, and the hope was expressed that the paper under consider- 
ation might not be the last. One more part has been issued, but 
only half of the proof had been read by the author at the time 
of his death. In this part there is a rearrangement of the genus © 
Gracilaria, notes on some other genera, and an article, “On the. 
Principles of Classification to be adopted for the Florideæ.” This 
he considered as of great importance, as a final statement of his
