|Title||A further Note on the Canines of Celebochoerus|
|Abstract||The genus Celebochoerus was based by me (Hooijer, 1948) on two fragments of upper canines of rather large size, different from their homologues in Sus celebensis Müller and Babyrousa babyrussa (L.), the two living species of Suidae of Celebes. The specimens originate from Pleistocene deposits at Desa Beru, Tjabenge (Sopeng district), about 100 km N.E. of Macassar, S. Celebes, and were collected by Mr. H. R. van Heekeren, prehistorian to the Archaeological Survey at Macassar.|
In the meantime I have received more specimens of upper canines, collected by Mr. Van Heekeren at Desa Beru and also at Sompoh, 12 km N. of Beru. These specimens, like those first described, are surface finds and consequently more or less water-worn. They show a great deal of variation in size as well as in the shape of their cross-section. As time fails now to give a description of all the fragments, I shall describe the best specimens first.
The largest specimen is the greater part of a right upper C, 11 cm in length. It originates from Sompoh. At the proximal end (pl. I fig. 3, to the right) the apex of the pulp cavity is shown. The tooth is slightly curved upward and backward and tapers distally. The cross-section is similar to that in the first described specimens (Hooijer, 1948, fig. 1 a, b): the anterior surface is at right angles to the upper and both surfaces possess a shallow longitudinal groove. The posterior upper and lower angles are gradually rounded off, and there is a sharp groove in the lower half posteriorly. The greatest diameters are ca. 42 mm horizontally and ca. 39 mm vertically.
The present canine is covered on all sides by a thick whitish layer also
