carefully armng-ed tables, keys, and summaries. Six of the species are 

 described in the present instidment ; seventeen remain over. 



New England HepaticsB.* — A. W. Evans publishes critical notes 

 on the folloAving eleven hepatic^e, several of which are new to the 

 eastern United States : — Neesiella jjilosa, Lophozia Hatcheri {L. Baueri- 

 ana), L. heterocolpa, L. ohtusa, Ohiloscyphus ascendens, C. fragilis^ C. 

 rivularis, CephalozieUa bifida, C. byssacea, C. pctpiUosa, Antlioceros caro- 

 linianus. In point of structure there appears to be nothing to distin- 

 guish the Antarctic Lophozia Hatcheri from the northern L. Baneriana. 

 As to ChiJosf'i/phi(s, Schiffner published a critical review of the European 

 species in 1912, and disagreement prevails as to the value of the various 

 species. Evans discusses in detail the structure of the three species 

 above cited, and the views of various authors as to their status. 



New West Indian Lejeuneag.t — A. "W. Evans gives an account of 

 some new hepaticse from Jamaica : — DiplasioJejeunea Johnsonii^ Lejjto'- 

 colea appressa, and RectoJejennea Maa-onii^ with detailed descriptions 

 and figures of their structure and specific characters. 



Bryophytes of Bolivia. J — J. Perkins gives an account of the 

 plants collected in the high Andes of Bolivia by K. Planz and Edith 

 Knocke, including a list of three hepatics, determined by F. Stephani, 

 and of twenty mosses, eleven of which are new and are described by 

 Y. F. Brotherus. 



Mosses of Borneo.§ — Y. F. Brotherus publishes a hst of the mosses 

 collected by H. Winkler in south-east Borneo, seventeen species, four 

 of which are new to science. Careful descriptions of these are supplied. 



Mosses of Lomhok.|| — Y. F. Brotherus gives a Hst of the mosses 

 collected in Lombok Island by the Elbert expedition to the Sunda 

 Islands. The number of species is sixty-seven, and among them are 

 eleven new species, the characteristic structure of which is described 

 and for the most part figured.

(By Mrs. E. S. Gepp.) 



Chlamydomonas.lT — P. Desroche has made experiments on Chlamy- 

 domonas Steinii to determine the effect of different rays of light on its 

 growth. He placed drops of nutritive solution containing zoosporangia 

 under three bell-jars with double walls. Through the first only the 

 red rays could pass ; through the second only the middle part of the 

 spectrum ; through the third only the blue, indigo, and violet. He
