To these ought to be added the Stenops potto BOSMAN, coming from the coast of Guinea. It has a short tail and a short index. In a .skull of a young Stenops potto, from the Museum at Leyden (Jig. 135), the distance Fig. Skull of Stenops potto. ( Original, Mus. Leyden.) between the two orbits is much larger than in Stenops javanicus, tardigradus and gracilis. It is the narrowest in Stenops gracilis, broader in Stenops javanicus, still broader in S. tardi- gradus, and the broadest in S. polio. In S. potto the circular boundary for the orbits is not so distinct as in other species. Fourth Genus. Lichanotus ILLIGER. Indri. The same form of teeth, but they have only two incisors in the lower jaw. This genus has but one species (L. Indri), distinguished by the want of the tail. Madagascar.

The Semnocebus approaches very much to Lichanotus, from which it differs by the exist- ence of a tail, and by the form of its skull. In a skull of the ^wz/«, Mus.
