INTRODUCTION 
Through the kindness of Professor T. C. Frye, of the University 
of Washington, the writer has recently received a large collection 
_ of Alaska Hepaticae for determination. It was made in 1913 under 
the auspices of the Kelp Investigation Expedition of the United 
States Bureau of Soils. The vast majority of the specimens were 
collected by Professor F rye himself, but his collection is supple- 
mented by a few specimens collected by Mr. A. B. Foster, Dr. 
G. B. Rigg, and Dr. R. B. W ylie. The specimens were all gathered 
near the coast, the easternmost locality being Verdure Creek, near 
the upper end of Portland Canal, and the westernmost, Mitrofania 
Bay on the Alaska Peninsula. In spite of the fact that the region 
Visited represents a relatively small portion of Alaska, the collection 
is the most comprehensive which has yet been brought back from 
the territory. It includes seventy species in condition to be 
identified, twenty being new to Alaska (or not before reported), 
seven new to America, and three new to science. The next largest 
collection, that of the Harriman Alaska Expedition, contained sixty- 
three species, thirty-nine of which were reported from Alaska for 
the first time. Of these thirty-nine species six were new to 
America and one, Scapania cordifolia K. Miill., was new: to science, 
although it was at first —— with angen ome
