now known with certainty from Alaska only, but it has been 

 reported from Japan and from antarctic America, and it is ex- 

 tremely probable that its range extends into British America. 



The Hepaticas brought back by the members of the Harri- 

 man Expedition, which are in condition to be identified, num- 

 ber 63 species, of which 38 are here recorded from Alaska for 

 the first time. Adding to these the 42 species previously known 

 from the Territory, gives a total of 80 species. In addition to 

 these there have been recently sent me specimens of Nardia 

 compressa, collected on Atka Island by J. M. Macoun in 1891, 

 and specimens of Grimaldia fragrans, collected in the Yukon 

 River district by Funston in 1894. Both of these are new to 

 Alaska and increase the number of known species to 82. Of 

 these 82 species, 7 (or about 9/0) are Marchantiaceas, 8 (or 

 about 10/0) are Metzgeriaceas, and 67 (or about 81/0) are Jun- 

 germanniaceEe. No representatives of the Ricciaceae or of the 

 Anthocerotacese are as yet definitely known from the Territory. 



In the following list the principal collectors are indicated by 

 initials only: ' T.' referring to Dr. William Trelease, ' B. & C.' 

 to Professor W. H. Brewer and Dr. W. R. Coe, and ' C. & K.' 

 to Messrs. F. V. Coville and T. H. Kearney, Jr. The other 

 collectors are named in full. A few specimens collected by 

 Professor W. A. Setchell in 1899 are also included in the list, 

 although he was not a member of the Harriman party.
