Natural History of the Mammalia of India and Ceylon

Family Hylomidæ (Anderson)

The following little animal has affinities to both Erinaceidæ and Tupaiidæ, and therefore it may appropriately be placed here. Dr. Anderson on the above ground has placed it in a separate family, otherwise it is generally classed with the Erinaceidæ. Its skull has the general form of the skull of Tupaia, but in its imperfect orbit, in the rudiment of a post-orbital process, and in the absence of any imperfections of the zygomatic arch and in the position of the lachrymal foramen it resembles the skull of Erinaceus. The teeth are 44 in number: Inc., 3—3/3—3; can., 1—1/1—1; premolars, 4—4/4—4; molars, 3—3/3—3, and partake of the character of both Tupaia and Erinaceus. The shank-bones being united and the rudimentary tail create an affinity to the latter, whilst its arboreal habits are those of the former.
