over seven pages fall of quotations to p. 183, line 1 from below. In 

 connection witli this remark, I may perhaps point out that, accord- 

 ing to a communication by the author, the asterisks and dashes 

 after the paragraphs containing the geographical distribution have 

 the same meaning as the corresponding signs used by the author 

 in his Flora tier Mark Brandenburg, and are devised to indicate 

 briefly the extension of the range of a species beyond the area of 

 the Synopsis, a dash above the asterisk designating that the northern 

 limit of the species lies within the area, one on the right side that 

 the species does not extend east of the area, &c. The nomenclature, 

 of course, strictly follows the new Berlin rules, sometimes perhaps 

 too strictly ; for it seems to us that cases like that of Larix Larix 

 or Cedrus Cedrus might have been allowed the benefit of the more 

 liberal construction of the rules followed in Abies alba (instead of 

 A. Picea). Eules intended to regulate the nomenclature of a 

 science which has a history as well as future, and grows and de- 

 velops like an organism, should not be made into a Procrustean bed. 

 The present year will carry the work to the end of the seventh 

 part. May equal success crown also in future the untiring efforts 

 of the authors. ^ o

Moss Exchanqe Club Catalogue of British Hepaticiv. Compiled by 

 the Eev. C. H. Waddell. London : Wesley & Son. 1897. 

 Price 6d. Pp. 8. 



This Catalogue, primarily intended for the use of the Exchange 

 Club managed by the author, deserves the attention of all who are 

 interested in the Hepatics of this country. With its fifty-nine 

 genera and 220 species it provides the only complete list yet pub- 

 lished. It is doubtful whether certain of the species and one or two 

 of the genera will retain the position here assigned to them ; but this 

 need not be considered now, for the Catalogue does not claim to be 

 authoritative. The classification adopted is founded upon that laid 

 down by Spruce in his Hepaticm of the Amazon and Andes and later 

 works. Mr. Waddell is to be congratulated upon his work, and 

 will doubtless find a ready sale for it. A trustworthy enumeration 

 at the very least was badly wanted. The new Catalogue is more 



than a mere enumeration. . ^
