besides much Anthoceros laevis L. Along the wet clayey road between Lunkasoo 

 and Staceyville there were unlimited quantities of A. Macounii Howe. 



Of former additions to the Maine hepatic list first collected on Ktaadn., 

 E. D. Merrill, in 1898, got Scapania convexula, described as new by Miiller.* 



Mr. Collins, in 1900, found Gymnomitrium concinnatum (Lightf.) Corda, 

 Nardia obovata (Nees) Carringt., Lophozia harhata (Schmid.) Dum., L. lyco- 

 podioides (Wallr.) Cogn. (new to New England), L. alpestris (Schleich.) Evans, 

 and Scapania umbrosa (Schrad.) Dum. 



The Cowles party, in 1902, working in the North-West Ba'sin, acquired 

 MarsMpella aquatica (Lindenb.) Schiffn., Lophozia confertifolia Schiffn., (new to 

 North America) and Ptilidium pulcherrimum (Web.) Hampe. 



Dr. Evans, in 1908, in an ascent via the Abol Slide, collected Marsupella 

 ustulata (Hiiben.) Spruce, and Lophozia bicrenata (Schmid.) Dum. 



The writer, in 19 16, added Gymnomitrium corallioides Nees, Nardia Geoscyphus 

 (De Not.) Lindb., Lophozia Kunzeana (Hiiben.) Evans, Cephaloziella bifida 

 (Schreb.) Schiffn, and C. Starkei (Funck) Schiffn. 



Some notes on the species either lacking, or overlooked, may be of interest. 

 The writer collected all the hepaticae on Mr. Collins's list, with the exception of 

 Scapania umbrosa (Schrad.) Dum. Of the two closely related Sphenolobi, every- 

 thing collected was exsectaeformis (Breidl.) Steph. No Lophozia longidens (Lindb.) 

 Macoun was noted, and no Scapania nemorosa (L.) Dum. 



Marchantiaceae were entirely lacking until well down the trail, and then 

 mainly Conocephalum. Lophozia lycopodioides (Wallr.) Cogn., while abundant, 

 and typical about the camp, was inclined to be var. obliqua K. M., up above. 

 Cephaloziella species were less numerous than in the White Mts. No Porella 

 or Radula was collected by the writer. 



A more leisurely survey of the mountain is necessary than that which the 

 writer was enabled to bestow upon it during her ten-days' stay, but it would 

 undoubtedly yield many species, including some more denizens of a distinctly 

 arctic character, besides those already upon our list. 



The attention of collectors is called to this mountain, a New England — No! 

 a National asset, as yet unrealized by the majority of our fellow-citizens — • Ktaadn 

 the Magnificent! far to the north of Boston!

* A quantity of Mr. Merrill's bryophj'tes, presumably from the same expedition, now in the 

 hands of Dr. Riddle, may prove to contain some of the additional species listed below, in which 

 case they will antedate these records.
