the Bolivian flora, which he enumerates in tables geographically arranged 

 according to the localities which he explored, including the same in a 

 bryo-geographical sketch. The new genera denned are Polymerodon 

 (to be referred perhaps to the Dicranaceas), Simplicidms (with the vege- 

 tative habit of a Fissidens), Wollnya (resembling Splachnacese in ha I tit 

 and Bryeoe in peristome). 



Sphagnaceae of Siberia.* — C. Jensen gives an account of the Sphag- 

 naceas collected by Arnell (in 1876) and others. These comprise twenty- 

 seven species and some varieties. In addition to synonymy and distri- 

 bution, the author supplies critical notes on the plants. The rest of the 

 mosses and the hepatics were published by Arnell and Lindberg in 1889. 



Mosses of Japan and Corea.f — J. Cardot publishes a further list of 

 new mosses collected by Faurie and others in Japan and Corea, being 

 a sequel to the lists in Bull. Herb. Boissier vol. vii. (1907) p. 701), 

 and vol. viii. (1908) p. 331. The present paper contains descriptions of 

 sixty-one species and varieties, nearly all of which are acrocarpous. 



C. F. Austin: North American Bryologist.J — E. Gr. Britton gives 

 a biographical account of Coe Finch Austin (b. 1831, d. 1880). Many 

 of the mosses and hepatics issued in his published sets were collected 

 near his home in Closter, New Jersey. His Musci Appalachiani con- 

 tained 450 numbers and were issued in 1870, followed by a Supplement 

 of 100 numbers in 1878 ; and his Hepaticee Boreali-Americana?, with 

 150 numbers, were issued in 1*78. His moss herbarium is in Columbia 

 College, New York, and his hepatics in Manchester. He published some 

 twenty-eight papers. 



Charles Lacouture.§ — C. C. Haynes publishes an obituary note on 

 Charles Lacouture, who died at Dijon on November 7, 1908, aged 

 76. He was the author of an illustrated synoptical key to the French 

 hepatics (1905), and of a similar key to the forty odd subgenera of 

 L&jeunea (1908) ; and he left a nearly completed key to all the 

 known genera of hepatics, which it is expected F. Stephani will finish 

 and publish.

Phycoerythrin.|| — E. K. Hanson publishes some observations on 

 phycoerythrin, the red pigment of deep-water algas. The object of his 

 study was to throw light on (1) its role in assimilation, and (2) its 

 chemical nature, suggested to be protein. The preparation of material 

 was a difficulty, as the colouring matter occurs in very small proportion 

 in most red algaa. Ceramium rubrum and other species of the genus 

 yielded a fair quantity. The author describes his methods and then
