TION OF ONE NEW SPECIES. 
(PLATE 227.) © 
The genus Scouleria was founded by Wm. Hooker in 1830, 
on specimens collected by Dr. Scouler at Observatory Inlet, de- 
scribed as S. aquatica, and subsequently distributed in Drum- 
mond’s Musci Americani as No. 63, collected in the Columbia 
and Portage Rivers. A few autograph duplicates of Dr. Scouler’s 
Specimens were also distributed in this country, and Dr. Torrey 
was fortunate i in possessing one of them, as well as a set of Drum-

_ dn. 1851. GC. Mueller ' transferred Scomleria aquatica to Grimmia

followed his example. Mitten in 1869 also subordinated the 
‘genus to Grimmia, describing one new species Grimmia patagonica 
(Journ. Linn. Soc. 12: 96, 1869), which Jaeger (Adumb. 1875) 
_ changed to Scouleria patagonica.. Since then the genus has been
