The posterior nares are narrow, as in other members of the genus 
(6 mm.), and the contours of the lower jaw also conform to the;, pronolagus 
type- 
This skull then belongs! to a hare, which, in its cranial characters, 
was more heavily built than either P. ruddi or P. crassicaudatus. It agreed 
with the former species in its broad arch nose and in the relations of the 
postorbital processes, the anterior shoulder of the zygoma-root, and the 
upper molars. 
On the other hand the palatal foramina, the incisors, and the large 
bullae are characters which it shares with P. crassicaudatus.
