Two nearlj' pei-fect heads, widely differing from all other 

 South African species. 



Head triangular; proportion of length to breadth about 2 to 3; 

 genal angles rounded, with small, sharp spines directed outwards 

 from the bend in the margin. Glabella acutely domed in front, 

 with irregular sides, divided from the cheeks by a distinct furrow; 

 broadens out forwards from the third axial furrows. First pair 

 of axial furrows long and shallow, directed outwards and oblique- 

 ly forwards, axial ends bent backwards. Second pair short and 

 shallow, not reaching the marginal furrows ; directed less oblicjue- 

 ly forwards than the first pair ; axial ends bent backwards. Third 

 pair very deep, reaching the marginal furrows, still directed 

 slightly forwai-ds : axial ends twisted backwards and then for- 

 wards. Axial ])ortion flat, slightly more depressed than the termi- 

 nal lobe. Neck furrow deep and straight, with marginal ends 

 curved forwards ; becomes broader and less deep over the axis. 

 Neck segment smooth, deeply indented at the axial furrows. 

 Cheeks rounded and smooth, somewhat swollen behind the ej-es 

 and steep in front of them, with a definite l)order on the sides 

 almost as distinct as the neck segment, but without the furrow. 

 Eyes prominent, lunate ; facets borne on a plate slanting up- 

 wards towards the axis ; viewed from above they api)ear semi- 

 circular with equal vision forwards and backwards. Sutures run 

 inwards and a little backwards from the margin to the base of the 

 eye, thence forwards and outwards and round the front maro-in 

 of the glabella. Refiexed portion with a narrow vertical border 

 in front, thence directed hoiizontally backwards : cheeks level 

 with the refiexed margin. Inner margin of the under surface
