NATURE NOTES 
and Mr. Lydekker some ten years ago, since which date several most interesting 
new types, such as the Australian Marsupial Mole, the Okapi of Equatorial 
Africa, and the “sub-fossil” Ground-sloth Glosnotherinm of Patagonia, have 
been discovered. When we say that Mr. Beddard gives a systematic account 
of all the more important genera, both living and extinct, dealing not only with 
their distinctive structures, but also with their habits, and yet manages to devote 
upwards of a sixth of his work to such valuable preliminaries as the comparative 
anatomy, geographical distribution and possible forerunners of the Mammalia, 
it will be seen th.at in condensation alone he has performed a remarkable feat. 
Australian Anteater {Echidna aculeaia), x From Beddard’s “ Mam- 
malia,” by permission of Messrs. Macmillan and Co. 
He reproduces, with but brief comment, Wiedersheim’s admirable figures of the 
different forms of the stomach in the Class, and devotes no less than eighteen 
pages to the dentition, whilst in the systematic portion of his work, he, as we 
think, rightly gives more space to the primitive groups, the Edentates and 
Marsupials, than to higher and more familiar types. Man and Pithecanlhropus 
between them occupy only the final six pages of the work. Nearly three 
hundred illustrations, as excellent as those in the previous volumes of this series, 
adorn the work, and, by the courtesy of Messrs. Macmillan and Co., we are 
able to give, as examples of these, three characteristic Australian species. We 
could have wished that Ocapia, Glossotherium and Pithecanthropus, had been 
included among the types illustrated.
