ii6 ANNALS OF SCOTTISH NATURAL HISTORY 



long and narrowly cylindrical, 40 to 65 by 4 to 6 /*, and 

 these long cells continue far up the pagina on its central 

 aspect, while near the margin the cells are abruptly changed 

 into those seen in the upper part of the leaf, viz. roundish, 

 separate, and distinct, and their size as much as half as 

 large again as those in the normal form, 8 to I 2 yu, ; pagina 

 unistratose ; the nerve soon becomes red, is about 55 fj, 

 broad, and continues of this breadth for three-fourths up, 

 afterwards it narrows and ends either just below the apex 

 or is prolonged into it, prominent on the back and slightly 

 convex in front, so as to render a cross section broadly 

 elliptical or nearly circular in outline, with a row, in the 

 centre, of 3 to 5 pellucid cells, 9 to I 3 JJL diameter, and 2 

 rows of minute cells on either side of the central row, which 

 however, near the apex, degenerate into one row on each 

 side ; large hemispherical papillae (4 to 6 yu, in height) cover 

 both surfaces of the nerve as well as both aspects of the 

 pagina, while the margin is merely crenulate or, at times, 

 entire : the margin is closely reflexed to near apex and, near 

 the middle of the leaf, reflexed as much as 60 /i. In the 

 other specimens the papillae are minute, scarcely half the 

 height and usually bigeminate. I may mention also that 

 the whole areolation of the Lawers' specimens is of a fulvous- 

 yellow, even to the base. Although this moss is barren, I 

 am persuaded that the differences indicated are of sufficient 

 significance to warrant specific distinction. Accordingly I 

 give this moss the name, Barbula chlorophana. 



Rhacomitrium microcarpum has turned up in two places 

 near Killin, and, in all likelihood, Didymodon luridus, on 

 rocks partially covered with earth. As the latter has only 

 been seen in a sterile condition, I fear to pronounce definitely 

 concerning it, as the areolation is scarcely of a sufficiently 

 distinctive character. 



ZOOLOGICAL NOTES. 



Melanie Mountain Hare in Roxburghshire. Early in March I 

 received a black variety of the Mountain Hare (Lepus timidus) for 

 preservation, which had been shot near Galashiels. It is the first 

 black specimen of this animal that I have ever seen. ROBERT 

 SMALL, Edinburgh.
