The first toe, if the terminal joint is included, reaches only to the extremity of the 

 second metatarsal, which does not reach quite so far forwards as the third and fourth, 

 which are of equal length. The fifth metatarsal is little more than half the length of 

 the fourth; and its first phalange reaches only to the end of the fourth metatarsal. 

 The united tibia and fibula are one fourth the length of the femur longer than it ; and 

 the extreme length of the foot from the heel to the extremity of the third toe is only a 

 very little shorter than the tibio-fibula.

From the foregoing description of the skeleton and dentition of this remarkable form, 

 it would seem that Hylomys is more closely allied to Gymnura and Erinaceus than to
