as a whole than has been possible to obtain hitherto. Especially 

 in her treatment of the Thuyoideae and Claviferae is the author 

 to be commended. One is at first struck by the very large num- 

 ber of species reduced to synonyms under such species as G. 

 cupjressoides and G. racemosa, which latter name replaces C. 

 clavifera as generally used hitherto. But one who has had the 

 opportunity of examining large sets of specimens can hardly fail 

 to approve the specific limitations adopted by the author, for not 

 only are the species themselves very variable but, also, one more 

 than suspects that many of the species previously described 

 owed their assumed characters to some accident of preparation. 

 The arrangement of the present monograph seems to us to be the 

 natural one and one which is likely to be generally adopted.

11. De dispositione Delesseriearum ; by Prof. J. G. Agardh, 

 pp. 239, 8°, Lund, 1898. — This volume, which forms the third 

 part of the third volume of the classic Species Genera et Or dines 

 Algarum, of which the first volume appeared in 1848, is a rare 

 illustration of continued scientific activity in a field in which the 

 writer has been a master for more than sixty years. To Amer- 

 ican algologists it is of special interest, as it includes a revision 

 of the species of Nitophyllum, Delesseria and related genera from 

 our Pacific coast which were originally described in Agardh's 

 Epicrisis and subsequent memoirs, to which are added JSfitophyl- 

 lum macroglossiwi, N. stenoglossum, JV. marginatum, JV. Far- 

 lowianum, JYeuroglossum lobuliferum. The new genus Erythro- 

 glossum with five species includes Delesseria Woodii and D. 

 Californica, and Apoglossum includes D. dicijnens, all three 

 Californian species. The new genus Calloseris is founded on a 

 single species, G. JTalliae, from Florida. w. g. f.
