HORN EXPEDITION—MURIDiE. 
399 
laid forward do not quite reach the eye; the liairs of the tail are long and almost 
conceal the scales, which average twenty to the centimetre; mammie, 0-2 = 4. The 
palate ridges are three predental undivided and five interrupted interdental, the 
fourth reduced to two tubercles. 
Sh ///.—Moderately stout, ridges low but discernible. The posterior wall of 
the orbit is deflected outwards, giving a squarish appearance to the brain case; 
the anterior zygoma root projects slightly above, but the front edge is not 
markedly concave. 
Teeth .—The molar teeth are somewhat worn, the second and third lamina 
of the upper vh having united on the inner side into a C-like figure; otherwise 
they agree very well witli AVaterhouse’s illustration. The upper molars may be 
briefly described as follows, but as in other cases the figures are mainly relied 
upon, explaining what the best possible description would fail to convey :—;/d, the 
anterior cusp is doubled, partaking almost of the character of a lamina. In the 
first lamina proper the inner cusp is remarkably large, while the outer one is 
equally small. The condition of the second and third laminre has been referred to. 
the antereo-intei-nal cusp is large; the remaining cusps are united in a similar 
manner to the second and third laminje of vh. vf quite worn down ; mai'kings 
show that it possessed three cusps.
