Remarks on the New Species of Muse i from Quito and Swan 

 River, indicated by Da. Taylor in the London Journal of 

 Botany, Vol. V. p. 41, by William Wilson, Esq. 



{With Two Plates, Tab. XV. XVI.) 



The writer of these remarks had devoted much time to 

 the investigation of most of the species here enumerated 

 hefore Dr. Taylor's publication appeared. In not a few 

 instances his conclusions were at variance with those of 

 Dr. Taylor, and he has since carefully reviewed every 

 species, for which task his long and familiar acquaintance 

 with Sir W. J. Hooker's Herbarium has given him superior 

 advantages. He has also gladly availed himself of the 

 specimens most liberally lent to him by Dr. Greville and 

 Dr. Taylor for this purpose. — He oilers his remarks, with 

 deference, to assist those who may hereafter study the 

 synonymy and affinities q( this tribe. 



Phascum cylindricum. -i-lntermediate forms rather show 

 this to be only a variety of P. tetragonum. 



Gymnostomum linearifolium is Zygodon cyathicarpus, (Mon- 

 ta gne, in Annales des Sciences Nat. Aug. 1845, p. 106 !) 



Gymnostomum brevicaule seems scarcely different from 

 Pottia minutula var. y . obtusa, (Bruch et Schimper). — The 

 'eaves are perhaps more elliptical, the nerve scarcely excur- 

 rent, and the operculum is apiculate.
