Skull of nearly adult Bear from Norway. The palate is very con- 
cave, especially in the middle of its length, in a line with the first large 
false molar ; the hinder edge rather concave, and smoothed behind, 
near the front edge of the internal nostrils, which is thin and regu- 
larly arched ; the aperture of the hinder nostril large, rather broader 
in front than behind. The hinder tubercular grinder rather short. 
Forehead quite flat, produced behind to a line over the ears, not con- 
vex above the orbits, narrow between the orbits. Nose broad, flat 
at tip ; nasal bones only extending to rather behind the front edge 
of the orbit, not nearly so far as in U. arctos of Sweden. The aper- 
ture for the passage of the artery to the palate in a line with the 
front edge of the hinder grinder. Length of the skull below 113 
inches, of palate 5? inches ; width at condyle of lower jaw 64 inches, 
of nose behind, at aperture 22, at canines 23, of nose-aperture 12 inch, 
between orbits 23 inch, at back of orbits 33 inches. 
I think that the skeleton which is in the British Museum, which 
was received from Mr. Brandt of Hamburg as that of a Bear from 
Norway, and named U. norvegicus, is the Myrebiorn or Ant-Bear 
of Worm. 
I am not so sure that it is the Ant-Bear of Eastern Siberia, figured 
by Eversmann as U. formicarius, as the figure of the skull does 
not quite agree with the Museum specimen: the flat plane of the 
forehead is not carried so far back on the crown as in the skull 
here described. If it is not the same, the U. formicarius of Siberia 
must be, from the description, a nearly allied species of the same 
enus. 
The figure of the skull of the young Brown Bear from Norway, 
figured by De Blainville (Ostéogr. t. 7), is probably a young skull of 
this species: it differs from the figures of the skull of the other 
European Bears in the same work, in the forehead not being separated
