ON A SUB=FOSSIL HARE FROM A CAVE DEPOSIT 
AT GODWAN RIVER. 
By Dr. Lyster Jameson. 
In a small collection of animal remains brought from Godwan River, 
on the Delagoa-Pretoria line, by the late Dr. Karl Wildner of Johannes- 
burg, was the skull of a hare of the genus Pronolagus, which seems to 
occupy a position intermediate between the two living representatives of 
the genus P. crassicaudatus (Is. Geoff.) and P. ruddi (Thomas and Schwann), 
Abstr. P.Z.S. No. 18, p. 23, April, 1905, and P.Z.S., 1905, Yol. I, p. 272, 
pi. XVI, and which I propose to call Ronolagus intermedins , n. sp. 
The skull was found in a thin bed of red earth, cemented together 
into a solid matrix by carbonate of lime, in a lime deposit in the face of 
a hill which was being worked for commercial lime. I have not yet had 
an opportunity of examining the spot ; but, from Dr. Wildner’s descrip- 
tion, the deposit is probably the remains of a cavern in the Dolomite, 
which has become secondarily obliterated by stalagmitic deposits. 
Such deposits of stalagmite are being worked for lime in many parts 
of the Transvaal where the Dolomite formation occurs. Beds of red 
earth, representing former floors of the caves, are common in these 
deposits, and in several places (e.g. Wonderfontein, near Bank Station, 
and Sterkfontein, near Krugersdorp) contain bone braccias that ought to 
be systematically studied before all these deposits have been passed 
through the kilns. 
The type specimen of this hare consists of a fairly perfect skull and 
lower jaw. 
Description : Skull intermediate in size between P. crassicaudatus and 
P. ruddi ; heavily built. Muzzle broad proximally, relatively and 
absolutely broader than even in P. ruddi. 
The frontal bones are lost, but from the contour of the maxillae and 
premaxillae it would appear that the frontal profile was probably more 
convex than in P. ruddi. 
Postorbital wings resemble those of P. ruddi, but the angle between 
them and the brain case is narrower. 
Anterior shoplder of the zygoma not produced forward as in P. ruddi, 
but not so acute, and with a more obtuse angle between itself and the nose. 
The palatal foramina resemble those of P. crassicaudatus, but are 
broader in the middle, and slightly constricted posteriorly by their 
inwardly directed edges. 
Bullae very large, as in P. crassicaudatus. 
Incisors deeply grooved. Upper molars resemble those of P. ruddi, 
in that the uncrenulated parts of the anterior enamel walls of the posterior 
laminae extend about half way across the tooth, and further in having 
the crenulated outer parts of the posterior enamel walls of the anterior 
laminae and of the anterior enamel walls of the posterior laminae about 
equally developed. 
The anterior wall of the anterior lower premolar is only faintly 
crenulated. The lower molars are not well preserved.
