Those things in which it agrees with the Marsupials are not the 

 same as in the Hedgehog; it differs from both Insectivores and 

 Marsupials in its own peculiar way, and in some things is more 

 archaic than either. This type appears to me to be a waif from a 

 large group of forms that were beginning to be transformed out of 

 the Metatheria into the Flying Eutheria (Chiroptera), certain of 

 which, this living type among the rest, being arrested at the general 

 level (or platform) of the Insectivora ; they are equal to, rather than 

 members of, the order Insectivora. The last type to be mentioned is 

 the Tupaia, an Eastern form, rather high in position, yet combining cha- 

 racters for the first time seen in the Mammalia, namely, a perfect orbital 

 ring, with old Metatherian structures, such as the large os-bullae, the 

 small external and internal pterygoids, and a soiuewhat absorbed hard 

 palate. The last three kinds, Bhynchocyon, Galeopithecus, and Titpaia, 

 all show a curious mixture of that which looks upwards to the 

 highest types, and of that which has been retained from the lower and 

 more archaic forms of the Mammalian class.
