The following teeth, which are absent in the Cat, are present in the Genet :—

one-rooted in the Cat, is two-rooted, as is also or DL has its crown more 
triangular than the Cat’s, the heel (or talon) being smaller. 5-3 is much like 
that of the Cat. The upper sectorial P.4 differs from the Cat's in that its 
anterior outer cusp is smaller, its third outer cusp, or talon, distinctly bilobed, 
and its inner cusp larger and more produced from the general surface of 
the tooth. The homologous lower tooth, 5, is very like that of the Cat. 
The first upper molar ear very much larger than that of the Cat ; its antero- 
posterior extent compared with that of P. 4 taken at 100, is in the Genet 37:5, 
in the Cat, at most, only 30-0; its transverse diameter compared with that of 
P. 44 ken at 100 is in the Genet 140-0, in the Cat only 80:0. Moreover it 
has three roots instead of only two asin the Cat. Its functional surface is 
trihedral and presents two outer and one inner cusp, with an external cingulum, 
which is very prominent at the outer anterior angle of the tooth. Between 
this and the two outer cusps is a flattened somewhat elevated (the skull having 
the basis cranii upwards) surface. Mee iy shaped like ae but is very much 
smaller. The lower sectorial tooth, 7-4 (the analogue, but not the homologue, 
of the upper sectorial), has a much larger heel than has that of the Cat, and one 
which is divided into an inner and an outer cusp. There is also a distinct 
internal cusp, which is placed opposite to the principal external cusp. 47518 
a much smaller tooth than 5-4, and is generally quadrate or quadricuspidate, 
but may be trihedral, with two cusps in front and one behind. 
Of the milk-dentition I have not seen the first upper and lower deciduous 
molars. The second upper deciduous molar, ue has a rather more developed 
prominence, both in front and behind the main cusp, than has the tooth which 
replaces it. It is therefore very unlike that of tie Cat, which is a small simple 
one-fanged tooth. The second lower grinder 5-5 is like 5—; but its talon is 
larger and is distinctly divided. This tooth is not developed in the Cat. 
The deciduous upper sectorial, p.3 , agrees with that of the Cat in being quite 
unlike the tooth which replaces it, and in resembling P4 Tt differs from the 
permanent: sectorial (as is the case in the Cat) in that the inner cusp is re- 
latively smaller and nearer to the antero-posterior middle of the tooth. A 
slight ridge extends from this inner cusp to the anterior cusp; and on this 
ridge a very small fourth cusp is developed. The homologous lower tooth 
D3 is like Py but has a relatively larger talon, thus resembiing the Cat’s Ee 
he hindmost upper milk-molar oe quite like M.1 though not nearly so 
antero-posteriorly extended as is the deciduous upper sectorial ; it is (as in the 
Cat) larger in relation to it than is P.4 to M1 he inferior deciduous 
sectorial 5— is quite like ;-7, except that the antero-exterior cusp is much 
smaller than that immediately behind it. In this difference it agrees with the 
Cat’s Bat but it has not that excess of talon compared with which pa has
