ZOOLOGY AND BOTANY, MICROSCOPY, ETC. 783 



Mexican Moss-flora.* — J. Cardofc, in finishing his survey of the 

 moss-flora of Mexico, points out that the actual number of Mexican 

 mosses known is about 650, and may easily be doubled as time goes on, 

 The moss-flora is closely related to that of the West Indies and Andes, 

 and less intimately with that of the United States. It has but little in 

 common with that of westerly regions in the same latitude — Hawaii, 

 Formosa, Philippines. But curiously enough Mexico has some 20 species 

 iu common with India, and 14 others which are very closely allied with 

 Indian species. The author adds critical notes on more than 50 species, 

 which he is compelled to reduce to synonyms or to transfer to other 

 genera. 



Hepaticae of the Bahama Islands.! — A. W. Evans gives an account 

 of the hepaticae of the Bahamas based on material collected for the New 

 York Botanical Garden. Of the thirty-four species recorded, it is 

 curious that thirty belong to the Jubuleae, namely to Lejeunea and 

 Frullania. The other genera represented are Riccia, Marchantia, 

 Plagiochila, Radula, with one species each. Three new species are 

 described and figured. The flora has but little in common with that of 

 Bermuda — five species only. 



Hepaticae of Puerto Rico4 — A. W. Evans publishes his tenth 

 article on the hepaticae of Puerto Pico, and devotes it to a careful account 

 of Cololejeunea, Leptocolea, and Aphanolejeunea. Besides discussing each 

 genus critically, and describing the species in detail, he gives a chapter 

 to a description of the gemma? in the three genera — a character very 

 little studied, but showing great constancy. Cololejeunea contains about 

 twenty species, two of which are treated here ; Leptocolea includes about 

 fifty known species, four of which occur in Puerto Rico ; Aphanolejeunea, 

 a new genus, with the Irish A. microscopica Tayl., as its type, contains 

 about six species. In all the author describes three new species, re- 

 describes several others, and makes critical allusions to numerous others. 



New Zealand Hepaticae.! — L. S. Gibbs publishes a list of forty-one 

 hepaticae collected by her near Auckland, in the northern island of New 

 Zealand, in the spring season in 1007. The specimens were determined 

 by F. Stephani, and include four new species — Marchantia laceriloba, 

 Aneura papulolimbata, Calobryum Gibbsise, Lepidozia Gibbsiana. Some 

 notes on habitat are appended. 



Japanese Bryophytes.|j — S. Okamura gives descriptions in German 

 of the following seven new species of Japanese mosses : Dolichomitra 

 robusta, Cryphsea obovatocarpa, Dichelyma hatakeyamse, Calliergon 

 nakamurse, Astomum kiiense, Dicranella salsnyinosa, Meteor ium cuspi- 

 datum, and gives figures of most of them. 



He also describes If Trichocoleopsis sacculata, a new genus of hepatics,
