Rossettiaiiia, the antheridia of which he has discovered. The plant is 

 autoicous. A. Martin * gives a list of hepatics gathered in the department 

 Hantes-Pyrenees. A. J. M. Garjeanne f has studied the hepatics of the 

 Netherlands for five years and gives a list of 78 species, indicating 

 the provinces in which they occur. C. Massalongo % gives a critical 

 revision of the hepatics published in the Erbario Crittogamico Italiano 

 by De Notaris, twenty-five years ago. S. S. Radian § describes Bucegia 

 romana, a new thalloid genus gathered in the Carpathians. V. Schiffner |j 

 gives a critical and historical account of Dichiton calyculatum, a rare 

 African hepatic which, discovered GO years ago in Algeria only once, 

 has recently been found in the south of France, and is thus an addition 

 to the European flora. 



Gymnomitrium and Marsupella.^T — V. Schiffner publishes some 

 studies on critical species of these two genera. He finds Marsnpella 

 Sprucei to be distinct from 31. ustulata ; refers 31. olivacea to Gymno- 

 mitrium adustum ; describes as a new species 31. (Hyalacme) apiculata, 

 which Lindberg and others wrongly referred to G. condensata Angstr. — 

 this latter being also a Marsnpella and synonymous with Sarcoscyphus 

 icmi/h/x Limpr. ; and shows that S. alpinus Gott. is a true Gymno- 

 mitrium. 



North American Hepaticse.** — A. W. Evans in enumerating the 

 hepatics of the Yukon district, 38 in number, raises to generic rank 

 Mesoptychia, Lindberg's section of Jungermannia. The same author ft 

 gives a list of 32 hepatics of Minnesota, 16 of which are new to that 

 State, and 3 have not been recorded previously south of the Canadian 

 frontier. The same author %% also publishes lists of the hepatics that 

 occur in each of the six States of New England.

Algae. 



Marine Algse of the Shetlands.§§ — F. Borgesen publishes a list of 

 75 species from these islands, including all previous records as well as 

 the results of his own gatherings. Comparisons are drawn between this 

 flora and that of the Faeroes, together with notes on the local dis- 

 tribution of certain species.
