Hytomys—Tupanp. 99 
FAMILY HYLOMID (4Azderson). 
The following little animal has affinities to both Erinaceide and 
Tupaiide, and therefore it may appropriately be placed here. Dr. 
Anderson on the above ground has placed it in a separate family, other- 
wise it is generally classed with the Avinaceide. Its skull has the general 
form of the skull of Z/aza, 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 LAvinaceus. The teeth are 44 in number: Inc., ius : 
Po a ) 
can., — ; premolars, a ; molars, 3—3, and partake of the character 
of both Zupaia 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. 
GENUS HYLOMYS. 
Head elongate; ears round; feet arboreal, naked below; tail semi- 
nude; pelage not spiny. 
No. 157. HyLomMys PEGUENSIS. 
The Short-tailed Tree-Shrew. 
Hapitat.—Burmah, Pegu, Ponsee in the Kakhyen hills. 
Appears to be identical with the species from Borneo (7% sz/d/us). 
FAMILY TUPAIIDA: 
These interesting little animals were first accurately described about 
the year 1820, though, as I have before stated, it was noticed in the 
papers connected with Captain Cook’s voyages, but was then supposed 
to be a squirrel. Sir T. Stamford Raffles writes: “This singular little 
animal was first observed tame in the house of a gentleman at Penang, 
and afterwards found wild at Singapore in the woods near Bencoolen, 
where it lives on the fruit of the kayogadis, &c.” Another species, 
IT. Javanica, had, however, been discovered in Java fourteen years 
before, but not published till 1821. They are sprightly little creatures,
