ZOOLOGICAL NOTES 113 



PLAGIOTHECIUM TRICHODEUM. Stems slender, straggling, turn- 

 ing a dark colour, irregularly branched ; branches with leaves rather 

 laxly and divaricately disposed, as well as arranged almost bifariously, 

 slightly oblique, ovate or narrowly so, gradually acuminate and the 

 apex attenuated into a long, slender, hair-like acumen, not infre- 

 quently 0.27 mm. long, at times longer, margin plane or a little 

 incurved on one side at the rounded base, entire, shortly two-nerved : 

 cells at base bluntly oblong, generally in one row across, but in two 

 or three rows at margin, 0.025 to -35 by 0.018 to 0.022 mm. ; 

 the rest of the cells very long and sharply fusiform, or elongato- 

 rhomboid near the base, 0.09 to 0.13 by 0.007 to - 01 rnm., or 

 near the base, breadth as much as 0.013 mm - Slender stolons are 

 present, with minute narrowly-pointed leaves. The shape of the 

 leaf as well as the areolation are quite different from those of P. 

 piliferum, inasmuch as the latter has leaves nearly ellipsoid, and 

 cells the narrowest almost of any in the genus, viz., 0.004 to 0-005 

 mm. broad. 



CERATODON CONICUS is found in the Orkneys, more plentifully 

 in the Outer Hebrides, but hitherto only in a barren condition. In 

 1904, at Arisaig on the West Coast, I alighted on a curious form. 

 The tuft was rather lax, leaves much longer and more slender than 

 usual, slightly twisted in a dry state, nearly straight when wet. 

 The remarkable condition is that the sharply-pointed, excurrent 

 nerve is extruded beyond the pagina from 0.3 to 0.6 mm. and 

 turns, at an early stage, to a deep red indeed, much earlier than 

 the reddening of the nerve at the base. I propose to name this 

 C. comcies, var. acicularis. 



Atrichum angustatum was got this year near Connel, and 

 Heterocladium heteropterum, var. flaccidum, as well as, in all likeli- 

 hood, Schistidhtm teretinerve (Limpr.), at Dunstaffnage Castle. 

 Hyp nu m hispidulum (Brid.), has also to be recorded from Ben 

 Lawers, as well as a rather curious form of H. chrysophyllum (Brid.).
