twist at all. It is perfectly straight and tapering, and when dry has 

 straight furrows : the lid seems to close in consequence of the swell- 

 ing of the columella, which diminishes its length." These different ap- 

 pearances may have depended upon the different ages or states of the 

 plant under examination.

On trees and rocks. Fr. Nov. — This has something of the habit of 

 the two last species; but its stems are leafy throughout ; the nerve of 

 the leaf is sometimes forked. Mr. Wilson finds, in Cheshire and near 

 Killarney, a state of this plant in which the outer ])eristome is abortive, 

 but the rudiments of teeth are visible. 



34. H. myosuroides, Linn, (mouse-tail Feather- Moss); branches 

 fascicled curved, leaves lanceolato-acuininate serrated the mar- 

 gin inflexed at the base, the nerve disappearing near the 

 middle, capsule ovate-cylindrical erect, lid rostrate. Linn. Sp.

Trunks of trees and rocks. Fr. Autumn. — Distinguishable from the 

 preceding by its slenderer habit, its more acuminated, less concave leaves, 

 with their shorter nerve, and reflexed margins, which are serrated for 

 nearly their whole length. Mr. Wilson finds a large var. of this, on 

 Conner Hill near Brandon mountain, Ireland.
