ZOOLOGY AND BOTANY, MICROSCOPY, ETC. 343 



Galls on Mosses (Journ. of Bot., Sept. 1905) is reprinted. C. C. 

 Haynes * has compiled a list of helpful literature for students of North 

 American hepaticae, being principally the papers of A. W. Evans, 

 M. A. Howe, and L. M. Underwood. 



Hepaticae of Puerto Rico.f — A. W. Evans, continuing his studies 

 of the hepaticae of Puerto Rico, publishes his eighth article upon the 

 Lejeunese, in which he treats of the genera Symbiezidium, Marchesinia, 

 Mastigolejeunea, Caudalejeunea, and Bryopteris. Symbiezidium is a 

 revived name, first published by Trevisan in 1877, and now utilised 

 by Evans to replace Platylejeunea Spruce. Four species of Symbiezidium 

 are treated of in the present paper. The genus Marchesinius was first 

 employed in 1821 to contain the species Jungermannia Mackaii ; and 

 the synonyms which have usually replaced it are Phragmicoma Dumort. 

 (1822) and Homalolejeunea Spruce. Evans follows Trevisan and 

 Schiffner in reviving Gray's genus with a feminine termination, and 

 treats of one species. Mastigolejeunea is represented by one species in 

 Puerto Rico, and Caudalejeunea by one species only, the author being 

 of opinion that the five so-called American species are simply forms of a 

 single one. Finally, one species of Bryopteris occurs in Puerto Rico. 

 The author carefully redescribes in detail and figures or annotates the 

 species of which he treats. 



Tropical American Mosses.} — R. S. Williams publishes some lists 

 of determinations, namely, twenty Colombian and two Guatemalan 

 mosses collected by H. Pittier, and eleven Cuban mosses collected by 

 W. R. Maxon. Among them are descriptions of four new species. 



West African Mosses.§ — E. G. Paris gives a list of thirty-eight 

 mosses collected by Pobeguin in Fouta-Djallon in French West Africa. 

 Among them are thirteen species new to science. Appended are deter- 

 minations by F. Stephani of six hepatics from the same collection. 



Hepaticae of New Caledonia and Tonkin. || — F. Stephani gives 

 descriptions of tweuty new species of hepatics, seventeen of which were 

 collected in New Caledonia and three in Tonkin by Le Rat and his 

 wife. 



Japanese Hepatics.^ — A. W. Evans gives an account of twelve 

 hepatics from the province of Tosa in Japan, most of them being new 

 records for Japan. Seven of them are described in detail and figured, 

 and five of them are new to science. The Japanese hepatics are of 

 unusual interest, and already more than 250 species have been recorded. 

 These are partly of northern, partly of southern type, as might be 

 expected in view of the many degrees of latitude over which Japan 

 extends. At least two endemic genera are found there, Gaviculuriu 

 Steph. and Makinoa Miyake, both monotypic. And a number of species
