<paragraph blockId="54.[165,1963,497,2981]" pageId="54" pageNumber="79">I`he speeimen on which this species is based consists of an imperfect right mandibular ramus in which the fourth premolar and the first molar are preserved. The fracture in front exposes the large anterior root of the premolar and the small posterior root is seen from the outer side. The lower front border of the crown ofthe premolar is slightly excavated apparently for the accommodation of the posterior edge of a very small, closely fitting third premolar. The socket for the base of the root of the incisor is seen 011 the inner side and indicates a tooth of comparatively robust proportions. Behind the first molar, the socket of the second molar is preserved, which, judging from its size, held a tooth considerably smaller than the first molar.</paragraph>
<paragraph blockId="54.[165,1963,497,2981]" pageId="54" pageNumber="79">The characters of the teeth are as follows: —Fourth premolar with eleven serrations on its edge; on its inner side, five complete grooves preceded by three half grooves; on its outer side, five complete grooves preceded by one half groove. First molar with four tubercles on its inner side and six tubercles on the outer side.</paragraph>

is especially interesting on account of the small number of grooves on the large cutting fourth premolar (approching the genus Meníscoëssus ill this respect) and the slightly backward curve of the tubercles on the outer side of the first molar, also suggestive of Meníscoëssus.

<paragraph blockId="54.[165,1963,497,2981]" pageId="54" pageNumber="79">In the figures of the type of the species, the teeth are shown as they appear in the specimen, but the first molar is evidently somewhat out of its true position of close proximity to the fourth premolar.</paragraph>
