NOTES AND LITERATURE. 
BOTANY. 
Porter’s Catalogue of the Bryophyta and Pteridophyta of 
Pennsylvania ! is an attractive volume of 66 pages. It is a list in 
which localities and collectors are indicated after the name of each 
species, and includes about 542 species and varieties. The cata- 
logue was compiled by Dr. Porter, the mosses revised by Mrs. Brit- 
ton, and the whole edited by Dr. Small. The names of such well 
known collectors as James, Austin, Muhlenberg, Porter, Rau, Garber, 
Burnett, Small, and Mrs. Britton appear many times throughout the 
catalogue and add much to its value. The arrangement of families 
and genera conforms very closely with that in Limpricht’s Die Zaub- 
moose, Some exceptions to this statement will be noticed, e. g., 
Hylocomium is placed between Brachythecium and Eurhynchium. 
Some of the most conspicuous changes in familiar generic names 
are the following: Mollia Schrank for Gymnostomum (partly), 
Gymnostomum Hedw. for Pottia, Weissia Ehrh. for Ulota, Leersia 
Hedw. for Encalypta, Astrophyllum Neck. for Mnium, Arrhenop- 
terum Hedw. for Aulacomnium (partly), Mnium Dill. for Aulacom- 
nium (partly), Webera Ehrh. for Diphyscium, Eleutera Beauv. for 
Neckera, and Forsstromia Lindb. for Leptodon. 
The catalogue is well bound in a very neat cloth cover and is 
clearly printed on good paper with a dead surface. It is absolutely 
indispensable to all students of the Pennsylvania Archegoniates and 
even the more general student should not neglect placing it in his 
library.
