and median generally noticeably less than the diameter of 

 the median, and always less, generally very much less, than 

 the long diameter of the lateral ; distance between the anterior 

 and posterior lateral eyes on each side much greater than that 

 between the anterior lateral and anterior medians. 



Loc. Pearston (Dr. R. Broom) and Jansenville {Miss 

 Leppan). 



Although the relative size of the eyes and the distances 

 between them are subject to considerable variation both with 

 age and individuals, the six specimens presenting the above- 

 described features may be at once distinguished from all the 

 examples of S. Schonlandi that I have seen. 



The females of this genus known up to the present time 

 may be diagnosed as follows : — 



a. No comb of spines on apex of protarsus of fourth 



leg beneath on the posterior side rufulous, Auss. 



b. A comb of spines on apex of protarsus of fourth leg 



beneath on the posterior side, 



a^. Some spines ou apex of protarsus of third leg 



beneath ; comb ou fourth protarsus consisting 



of about a dozen spines, the anterior of which 



are irregularly arranged and intermixed with 



adjacent setas. 



«^. About fifteen strong spines on apex of third 



protarsus beneath ; labial cusps 2 ; legs 



shorter oculatus, Poc. 



V. About half a dozen weak spines on apex of 

 third protarsus beneath ; labial cusps 8 ; legs 



longer ariifex, sp. n, 



V. No spines on apex of third protarsus beneath ; 

 comb on fourth protarsus formed of a single 

 definite series of 6-7 spines. 

 a^. Distance between the two lateral eyes on each 

 side about equal to the long diameter of the 

 posterior ; anterior laterals much larger 

 than anterior medians, the space between 

 them less than the diameter of the medians. . astutus, sp. n. 

 i'. Distance between the two lateral eyes never 

 less than twice the long diameter of the 

 posterior, and that between the anterior 

 median and lateral not less than twice the 

 diameter of the anterior median Schonlandi, Poc. 



Genus Pelmatorycter, nov. 



Allied to Cyrtaucheniiis, but with the ocular area scarcely 

 narrowed in front, the posterior line of eyes only the merest 

 fraction wider than the anterior. 



Eijes of the anterior line a little procurved, the anterior
