gathered and studied. Forster's name, ampullatus, revived by Rhoads 
(Science, N. S., vol. 15, p. 756, 1902) appears to have escaped the 
compiler, and seems applicable in place of rostratus for Hyperoödon. 
Four new generic names are proposed, to take the place of others 
that are preoccupied. Sphenodontherium for Sphenodon, Heterodon- 
therium for Heterodon, and Propareutatus for Pareutatus among the 
Edentata, and Odontocyrtus for Kurtodon among the Marsupialia. 
The compiler also deems it necessary to amend the name Tatu to 
Tatus. The index includes those specific names only that have 
figured in works published since the previous catalogue.

Britton's Manual. — In form, the recently issued second edition 
of this now well known work conforms closely to the first edition pub- 
lished in 1901. Analytical keys to the families, prepared by Wiegand, 
have been added to the prefatory matter, and a key to the genera of 
Compositz, also prepared by him, has been placed at the end of the 
treatment of that family. The lamentable absence of necessary syn- 
onymy from the first edition has been rectified to a considerable extent ; 
and in addition to such corrections as were possible in the original 
text, the appendix has been amplified by the incorporation of descrip- 
tions of over 100 species not recognized in the earlier edition, while, 
e. g., under Cratzgus, the fact that still others have been published 
is indicated.

A New North American Flora 2 Since the appearance some years 
ago of the latest fascicle of the Synoptical Flora begun by Asa Gray, 
there has been no evident effort to provide a collective systematic 
treatment of the plants of the entire United States, though several 
handbooks covering a part of the country have appeared. 
The fascicle now under review, though pertaining to a volume far
