teeth so much better preserved it will be better to regard it as 

 the holotype, and the British Museum specimen as a paratype. 



The British Museum specimen shows the skull to be at least 

 68 mm. in length. When complete it probably measured 75 mm. 

 The greatest breadth was probably about 40 mm. The orbit 

 looks upwards and outwards, and measures about 18 mm. in 

 diameter. From the front of the orbit to the front of the snout 

 is about 33 mm. The interorbital measurement is 18 mm., and 

 the intertemporal about 8 mm. There is no pineal foramen. 

 The postorbital arch is delicate but complete,

The upper incisors are lost from the Capetown specimen, but 

 remains of most are seen in the British Museum specimen. 

 There are apparently six, and together they measure 8 mm. 

 Behind i B there is a diastema of 1*5 mm. There are three small 

 canines. The first is less than 1 mm. in diameter, the other two 

 have each an antero-posterior length of about 2 mm., and the 

 third, nearly perfect on the left side, has a height of about 

 7 mm. The three canines together measure 6 mm. The first 

 molar is less than 1 mm. behind the last canine. There are 

 altogether eleven small, pointed, rounded, and unserrated molars,
