mostly vanishing at base of hyaline apex; leaf-cells in lower 
one half of leaf mostly square, up to 16 x 16 4, with thin walls 
and either hyaline or green, above to the hyaline apex green, 
somewhat elongate, with slightly thickened and rarely sin-

Arequipa, Peru, 2400 meters, on dry, exposed rock, Aug.

CoRRECTIONS. 
In Part I of this enumeration, Bull. N. Y. Bot. Garden 3 
(9): 107. 1903, the following corrections should be made. 
No. 1756, Campylopodium sulcatum n. sp.,is Campylopus 
(Pseudocampylopus) Krauseanus (Hpe. et Lor.) Par. 
No. 1748, Campylopus concolor (Hook.) Mitt, is evidently 
not that species but C. rosudatus (Hpe.) Mitt. 
No. 1759, Campylopus porphyreodictyon (C. M.) Mitt., is 
rather C. filzfoldus (Hornsch.) Mit 
No. 1741, Dicranella Subse ilata n. sp., equals D. 
Fitilariana (Mont.) Mitt.
