78 MR. 0. THOMAS ON THE [Jan. 3, 
Mungooses except the present species and those of the very distinct 
genus Crossarchus. The absolute sizes of the molars in Bdeogale 
are, however, as is shown in the table of dimensions, much less 
than in Ichneumia. 
The following table gives the dimensions of the last upper pre- 
molar and last molar of the species of Herpestes, with the percentage 
of the latter tothe former. The letters correspond to those denoting 
the different skulls of which the measurements are given above. 
Where the teeth belonging to a skull not previously referred to are 
measured, an asterisk is inserted instead of a letter.
