Platycran^ ELBGANS, gen. et sp. n. 
A slightly crushed skull found at Harrismith and in general shape 
somewhat resembling Trirachodon could not be placed in any of the 
known genera. It was named Platycraniffitori account of its great breadth 
across the temporal vacuities. The crushing had hidden or damaged the 
teeth, and only one canine of the lower jaw is visible. The lower jaw has 
now been ground away to such an extent as to show on one side the roots 
of the teeth in the upper jaw and on the other side those of the teeth in 
the lower jaw. It has thus been made out that there are at least eight 
molars in each jaw. Dental formula probably : r i. : -f ; c. : -J- ; m. : f ? 
Length of specimen from tip of snout to hinder end of parietal ridge : 
78 mm. Greatest breadth: 74 mm. The zygomatic process of the 
squamosum lies on the jugal, leaving a narrow strip of this bone uncovered 
along the temporal vacuity. The other uncovered part of the zygomatic 
process of the jugal gradually diminishes in breadth backwards.
