a great part of all the material preserved in the museums of the world. 

 The U. S. National Museum alone furnished 324 specimens, including 

 29 types, almost all of which were collected and presented by Dr. W. 

 L. Abbott. 



The treeshrews are here divided into two subfamilies, one containing 

 the treeshrews proper, 5 genera, and the other only the aberrant pentail 

 (Ptilocercus), with two subspecies. The generic names Anathana for 

 the Indian species and Tana for the long-snouted Malay forms are new. 

 In the restricted typical genus Tupaia there are 48 forms, 5 of which are 

 new; in Anathana 3, 2 of which are new; in Tana 12, 6 new; and in the 

 Philippine Urogale only a single species. The remarkable pentail 

 shrew (Ptilocercus), though described in 1848, is still so rare in collections 

 that only twelve specimens are loio'^ni to the author. 



In addition to the systematic account of the genera and species, the 

 paper includes a history of the animals, their discovery, systematic 

 history, geographical distribution, and habits. The osteology and 

 visceral anatomy are described at length. Details of the skull and teeth 

 of each genus are illustrated by text figures, and the external appearance, 

 the skeleton, and skulls of group's of species are shown on plates. The 

 geographical distribution of each form is shown by maps, and there are 

 extensive tables of measurements of specimens. N. Hollister.
