HORN EXPEDITION—MURIDS, 
Teeth .—The incisors are sliort hut strong and much curved. The molars are 
considerably worn. In there is no anterior cusp and no outer cusps, with the 
exception of a small unworn one on the first lamina; the inner cusps on the 
contrary are remarkably developed, an antereo-internal cusp as in AIus. An 
outer cusp may have been developed on the first lamina, but the teeth are worn 
below the point where it would have been possible to be certain. The position of 
the first lamina in nf' seems to indicate that an outer cusp has been developed at 
the expense of the inner one.
