p. 27-31). 
In Rev. Bryol. some of the dates that refer to the flowering 
on account of the printers blunder are a little wrong ; the 
dates are corrected in Grevillea. Thus at Hernôsand Grimmia 
apocarpa, Hedwigia ciliata, Ceratodon purpureus, Hypnum 
Scheberi and Hylocomium triquetrum are in flower about 
the 7% of July (not the 4 of July); Barbula ruralis, Pottia 
truncata, Dicranom undulatnm and D. fuscescens are in 
flower about the 93% of July (not the 15 of July) and 
Hypnum crista-castrensis, H. cordifolium and H. cuspidatum 
bloom in the same place about the 15 of August (not the 
5 of August). |

In most mosses the proembryo is confervalike. In Sphag- 
num, Tetraphis, Tetrodontium and Andreæa the proembryo 
at times forms a flatly expanded plate of tissue ; the author 
in this paper describes and pictures simular flat proembryos 
in Diphyseium and Œdipodium. In Diphyscium the proem- 
e bryo in its form very much resembles a Cantharellus 
Ra amongst the Fungi or the fruit of a Buxbaumia. In OEdipo- 
dium the author found gemmæ together with antheridia 
amongst the topleaves; the germinating gemmæ produce à 
flat proembryo ; in these respects Œdipodiam thus very much 
resembles Tetraphis, in which moss the gemmæ also produce 
a flat proembryo. #5 PTE
