II. MAMMALIA. 
[ 1905 ] 
INTRODUCTION. 
The number of papers recorded falls only a little short of that of last year. 
Among noticeable work, reference may be made to Mitchell’s investi- 
gations on the mammalian caecum, to those of Assheton and of Assheton 
& Stevens on the placenta, and those of Eqgeling on the lacteal and 
sudoriferous glands of the Marsupials. In connection with the latter, 
reference may also be made to other work on Marsupials and Monotremes 
in “Semon’s Reise.” Schlaginhaufen’s study of the papillary ridges 
and folds on the hands and feet of the Primates likewise claims a foremost 
place. Bardeleben’s views on the compound structure of the mammalian 
lower jaw, if substantiated, revolutionize our conceptions of this part of the 
skeleton. » « 
In systematic work Mearns’s paper on Philippine Mammals and 
Andersen’s Ohiropteran studies are noteworthy, as is Thomas’s descrip- 
tion of a new genus of Old World Cricetine Mouse. Reference may also be 
made to Elliot’s synopsis of American Mammals, to the completion of 
the supplementary edition of Trodessart’s “ Catalogue,” and to the issue 
of the second volume of British Mammals by Millais. Ridgway’s work 
on the Thoroughbred Horse is also one which has attracted much 
attention. 
In palaeontology Scott has added largely to our knowledge of the 
Patagonian Tertiary Mammal fauna ; while the new Ruminants from 
Californian caves described by Sinclair and others are of the highest 
interest.
