In the spring of 1858 the Rev. H. M. White of Andover brought 
to the Museum of Practical Geology some fossils from South Africa, 
with whose nature he desired to be acquainted. Among them was 
a fragment of the skull of a Dzeynodon, which, on comparison with 
the species already described, appeared to me to be new. On 
applying to Mr. White for further information about the fossil, that 
gentleman was good enough to put me in communication with its 
discoverer, Mr. J. A. Murray, who, on learning what interest attached 
to the skull, very kindly undertook to procure a supply of more 
perfect remains of the same Reptile from his father, who resides 
near Colesberg in South Africa, and not very far from the junction 
of the Orange and Caledon Rivers, where the fossil was found. 
Under these circumstances I thought it better to abstain from pub- 
lishing the new species until the promised additional materials should 
have come to hand. They arrived at the end of the year; and in 
January, 1859, Mr. Dew, of the British Museum, to whom I had 
entrusted the working out of one of the three (nearly entire) crania 
which Mr. Murray had sent, brought me the skull figured in PI. 
XXIII. [Plate 9], which, I had the satisfaction to find, fully bore 
out the view I had taken of the specific distinctness of the fragment
