.—The crown of both teeth is very flat labio−lingually and completely smooth on both lingual and labial crown faces. The labial crown face is plane and mesio−distally expanded with a cordiform outline. The basal edge is regularly convex. In lateral view, the labial face is also more or less flat without any concavity between central cusp and crown shoulder. The central cusp is slender, pointed and bent lingually. The transverse cutting edge is distinct and is continuous between the central cusp and the lateral heels. The cutting edge of the distal heel is angled forming an incipient, rudimentary cusplet whereas the mesial one is convex without any cusplet. The lingual face is much reduced and more convex. The lingual protuberance is prominent and supports a tapering and rather short lingual uvula. The root is completely missing.
