Mr. Wallace observed two male adult Orangs (Mias Kassu of the Dyaks), however, so very different from any of these that he concludes them to be specially distinct; they were respectively 3 feet 81/2 inches and 3 feet 91/2 inches high, and possessed no sign of the cheek excrescences, but otherwise resembled the larger kinds. The skull has no crest, but two bony ridges, 13/4 to 2 inches apart, as in the _Simia morio_ of Professor Owen. The teeth, however, are immense, equalling or surpassing those of the other species. The females of both these kinds, according to Mr. Wallace, are devoid of excrescences, and resemble the smaller males, but are shorter by 11/2 to 3 inches, and their canine teeth are comparatively small, subtruncated and dilated at the base, as in the so-called _Simia morio_, which is, in all probability, the skull of a female of the same species as the smaller males. Both males and females of this smaller species are distinguishable, according to Mr. Wallace, by the comparatively large size of the middle incisors of the upper jaw.
y men were paddling away with great vigour and were making rapid progress, the river flowing almost all the time northward, with deviations of a few degrees toward the east, in stretches from 2,000 to 6,000 m. in length. We crossed an immense basin 1,500 m. broad with most gorgeous sand beaches. Their formation in small dunes, occasionally with an edge like the teeth of a double comb, was most interesting. Once or twice we came to musical sands such as we had found before. Everywhere on those beaches I noticed the wonderful miniature sand plants, of which I made a complete collection.
