Ochotona yarlungensis

It looks like a Metaceratops, with a narrow dark grey circle on the lip edge.

The individual is small, with a body length of no more than 150mm. Its appearance is very similar to that of the Intercranial Pika, but there is a very narrow dark gray circle on the edge of the lip, and the outer part of the dark gray circle is grayish white. The bottom of the hind foot is densely furred, and the hair on the toe tip is long and thick, with the toe pads and claws hidden in the hair. The cranial face is relatively protruding, but relatively flat compared to the black-lipped pika. The fur is dark brown, not the light yellow-white of the black-lipped pika. On the skull, there is no oval foramen in the frontal bone, and the incisor foramen and palatine foramen are merged into one large hole.

It is endemic to China and is only distributed along the Yarlung Zangbo River in Tibet.
