valuta, tortuosa, &c. Of the Extinguisher mosses (Encalypta), it 

 is rather strange that I have found only one species — strejjtocarpa, 

 on lime walls. The most common species of Sjylachmim, with 

 their flagon-shaped fruit, are occasionally met with on the hUls on 

 dung. Diphyschim foliosum, and Tetraj)his peWwcic^a are 

 common. The interesting genus Grimmia is well represented. 

 This genus is peculiarly saxicolous, and their neat, elegant, 

 and darkish tufts adorn the otherwise bare and weather- 

 beaten granite rocks and boulders. Gritmnia ^jwfewiato, the 

 cushion moss, is not a common species in the Glenkens, 

 though foTind in abundance in the south of the county. G. 

 doniana and trichoj^hylla, with various species of Rhacomitriuvis, 

 almost clothe some of the Galloway dykes. Higher up 

 on granite is found in plenty G. Schultzia. My best finds 

 in this genus are G. commutata, on boulders by Loch Stroan, 

 evidently washed down by the Dee from some higher station, and 

 G. contorta, a very rare species, on the Milyea. The moistness of 

 the climate is very favourable to the gi'owth of Orthotrichums, no 

 fewer than thirteen species being found, and among these 0. 

 Hutclihisice, saxatile, rivulare, stramineitm, rujyestre crispum, 

 puchellum, Lyellii, &c. I have hopes of finding also 0. Drum- 

 mondi, calvescens, and sprucei. Bartramia ithyphylla is 

 plentiful along the Ken, and on stones in the river itself is 

 Cinclidotus fonthialoides. Bryums and Mniums are fairly 

 represented, and among them, Bryuni roseum, the most beautiful 

 of the genus, according to some. Aulacomnium androgynum, a 

 rare moss, I find only in one spot. All the 'Pogotiatums, and 

 nearly all the Polytrichums, are found. Neckera crisjm, a large 

 and elegant species, covers the stems of trees and rocks in the 

 glens, often in fine fruit. Neckera pitmila, a much smaller 

 species, is given as occuri-ing near the coast in Wigtown and 

 Dumfries. This I have not gathered. Leskea pulvinata, almost 

 unknown in Scotland, I have found in the Kenmure Holms. 

 Anomodon viticulosum, generally a common moss, occurs, with its 

 soft pale green tufts, only on the rock on which Kenmure Castle 

 stands. Hookeria lucens is common in some of the woods in wet 

 places. It is one of the most beautiful of vegetable forms, both 

 as regards its pale pellucid leaves and in its peculiar capsule, and 

 also as having, when fresh, the odour of the sweet violet. The 

 niimerous genus of Hypnum is well represented by about fifty
