Tate, (op. cit.) in the only modem 

 attempt 'o evaluate phylogenetic 

 relationships in the genus SfninthOp 

 m. separated the known species into 

 two divisions, A "primitive" division 

 characterised by striated foot-pads 

 and P 4 very large with P 1 (and 

 sometimes P') considerably reduced; 

 and a more "advanced" division com- 

 prising forms with granulated foot- 

 pads, no extreme enlargement of P 4 , 

 and P> subequal to P-\ Tate also

stated that those species in the • primi- 

 tive" division possessed stiongly built 

 skulls with well formed, low sagittal 

 crests and relatively small bullae; 

 and that lor I hose species in the 

 "advanced" division, the defmlag 

 characters could be accompanied 

 variously, by partial coalescence ot 

 individual loot pads, nat rowing of the 

 feet, caudal incrassation and enlarge- 

 ment of the ears and bullae.
