numerous critical notes are given. Considerable revision is also 

 evident in the Verrucariaceae. Each genus is illustrated by a plate 

 showing both macroscopic and microscopic characters, and a com- 

 plete index to both volumes is supplied. Part 1 being now out of 

 print, the author is engaged in a new edition of that volume.

Macvicar, S. M., The Student's Handbook of British He- 

 pa tics. (Eastbourne; Sumfield; and London: Wheldon & Co. 

 pp. XXIII and 463. 274 figs. 1912.) 



This is a complete illustrated handbook of the British Hepaticae, 

 issued at a moderate price. The number of species recognised is 

 274; and these are grouped in 73 genera. The System of classication 

 adopted is mainly that of Schiffner in Engler's Pflanzenfamilien. 

 The descriptions have all been rewritten on a fixed plan by Mr. 

 Macvicar, and present a uniformity of treatment, the more impor- 

 tant characters being emphasized by the use of italics. Simplified 

 keys to the genera and species are provided; and ample critical 

 notes on affinities, distribution. etc., are appended to the generic 

 and specific descriptions. The illustrations are reproductions of 

 drawings expressly prepared by the Rev. H. G. Jameson, and are 

 intercalated in the text. They show for each species the habit, leaf- 

 shape, areolation and other distinctive characters. A. Gepp.
