A total of 1616 cryptogamic species is now vbodried for Alaska, 
and is composed of 240 fungi, 459 alge, 400 lichens, 460 bryophytes, 
and 58 pteridophytes. The special sections on Alge, Mosses, and 
Hepatice, originally published in the Proc. Waaliiuston Acad. Sci., 
are reprinted here from stereotype plates, with a new consecutive 
pagination alongside that of the original seta The other sections

a EK. Cummings, in ‘working up the section on Lichens, 
has performed her task with care and thoroughness. She describes 
two new species, and adds three to the American flora and eighty- 
four to that of Alaska. A useful key is given under each genus, and 
the new species are figured on two plates. 
Prof. De Alton Saunders, who treats of the Algz, was one of the 
collectors of the expedition. With the help of other Rega s ied

Pacific Coast of North America, which he divides — oo regions 
—a southern, a Californian, and a northern. The s ern region 
extends from Point Conception southward to the pensien and is 
characterized by Merona giganteus, Sargassum Agardhianum, Ta-

region extends from Point Coneepken on the south to Puget Sound
