middle 1 * . The humerus is rather short, and powerful — 
shorter, and with the muscular ridges more developed, than 
in DUte/phys: the deltoid ridge is very prominent, projecting 
boldly about midway between the extremities of the humerus: 
the internal condyle is perforated. 
With respect to the remaining portions of the skeleton I shall 
only observe, that the ulna and radius are nearly in contact 
for their whole length, as in the Dasyures, and the same 
remark applies to the tibia and fibula. The metatarsal hone 
of the thumb is exceedingly short, and supports hut one 
phalanx, which is very small, and is so enclosed in the integu¬ 
ment, in the living animal, as not to project in the form of 
a free point. 
In the mounted skeleton of a Myrmecobius in the College of 
Surgeons, the inner toe or thumb of the fore foot has three 
phalanges *.

jaw larger than the others; premolars true molars 
studded with prickly tubercles ; those of the tipper jaw with 
triangular crowns; the last tooth very narrow, and trans¬

shorter, and has the spine much more developed. 
5 In a foot of a bear in the same museum, I find three phalanges to the 
inner toe, and M. De BlaiuriUe represents three to the inner toes of the fore 
and hind foot of Urrtis feror. I have never seen any other instance amongst 
the Mammalia in which the thumb has more than two phalanges.
