deenshire. Dr. Dickie finds the latter locality to be 

 tween 2400 and 2500 feet above the sea, and the former is 

 estimated somewhere between 2500 and 3000 feet. The 

 more productive locality is within a deer forest, where 

 sheep are not permitted to feed ; and the rocks of Glen 

 Dole are nearly or quite inaccessible to sheep. To these 

 circumstances, it may be conjectured, the preservation of 

 the species is to be attributed. Sheep and the dealers in 

 specimens are fast destroying the scarcer alpine species.

Native. Pascual. A local species, but its localities so 

 wide apart as to give it a large area in proportion to its 

 scarcity. Recorded for the counties of Wigton, Fife, 

 Forfar, Argyle, Ross and Sutherland. One of its locali- 

 ties may have considerable elevation ; namely, that given 

 in the Flora Scotica, " upon Cairn-dearg, one of the lower 

 heads of Ben Sguilert, a high mountain of Glen Creran, 

 in Upper Lorn." Possibly the range of mean temperature 

 might be extended one or two degrees lower.
