The Plant World for January comes in a new 
and improved garb externally and internally. 
The first article, by Alice Carter,Cook, entitled, 
‘Some Filipino Botany ’ comprises'some curious 
extracts from Blanco’s ‘ Flora.’ C. F. Saun- 
ders contributes ‘Hints for Beginners in the 
Determination of Grasses,’ and an excerpt from 
Bulletin 28, Division of Forestry, discusses 
‘The Threatened Destruction of the Big Trees 
of California.’ E. M. Williams‘describes ‘The 
Rosy Tricholoma’ and C. L. Pollard in the 
supplement continues ‘The Families of Flower- 
ing Plants,’ treating of various families of the 
orders Polygonales and Centrosperme. 
The American Naturalist for February is a par- 
ticularly strong number in spite of the absence of 
‘Editorial Comment and Reviews.’ It opens 
with a long and critical review of ‘Scharff’s 
History of the European Fauna’ by Leonhard 
Stejneger, Scharff’s work being praised for its 
admirable suggestiveness'and treatment of the 
subject, though Dr. Stejneger combats, we think 
successfully, his advocacy of an invasion of 
Europe from North America by way of Green- 
land. B. Arthur Bensley discusses ‘The Question 
of an Arboreal Ancestry of the Marsupialia and 
the Interrelationships of the Mammalian Sub- 
classes,’ considering that in spite of all evidence 
presented, Huxley’s theory of a genetic succes- 
sion of the former representatives of the Mono- 
tremata, Marsupialia and Placentalia is still 
entitled to first consideration. Arnold E. Ort- 
mann briefly reviews ‘The Theories of the 
Origin of the Antarctic Faunas and Floras,’

stating that heaccepts Hooker’s general idea of - 
the former existence of land connection between 
the southern portions of existing continents. 
Oldfield Thomas writes of ‘The Generic 
Names Myrmecophaga and Didelphis,’ claiming 
that the former name justly belongs to the 
Great Ant-eater and Didelphis virginiana to the 
Virginia opossum. The species cinereus and 
alstoni he considers as members of the genus 
Marmosa. Finally Edwin C. Eckel presents 
‘The Snakes of New York; an Annotated 
Check List,’ giving twenty-five species and sub- 
species, this being the first paper on the ophid- 
ian fauna of New York since Baird’s ‘Ser- 
pents of New York.’

ANTHROPOLOGICAL SOCIETY OF WASHINGTON. 
THE 315th meeting of the Anthropological 
Society was held on February 12th. Mr. Paul 
Brockett gave a short paper on ‘Ancient 
Mexican Books,’ and exhibited a copy of the 
Borgian Codex, lately reproduced through the 
munificence of the Due de Loubat. With the 
codex was shown a Japanese book, illustrating 
the similarity in methods of folding. ‘The Un- 
wrapping of a Peruvian Mummy,’ by W. H. 
Holmes and Walter Hough, proved interesting. 
A mummy pack from Peru was divested of its 
wrappings and from the swathings of cotton- 
bolls, leaves and cloth were taken the skeletons
