Sub-order O. Cyphophthalmi. 



The main work on this sub-order is H. J. Hansen and W. 

 Sorensen: On two Orders of Arachnida. Cambridge 1904. It 

 contains descriptions of two genera from Africa, each with a 

 single species, viz. Ogovia grossa H. J. H. & W. S. from Ogove 

 in sequatorial France, and Purcellia illustrans H. J. H. & W. S. 

 from Cape. The material to hand comprises a new species of 

 Ogovia and another form, for the reception of which a new 

 genus must be established. 



Ogovia Hans. & Sor. 



This characteristic genus hitherto comprised a single spe- 

 cies, 0. grossa, established on an adult female, and the male 

 was unknown. The new species, though easily separated from 

 O. grossa, agrees excellently with every character found in 

 the generic description excepting as to two particulars, viz. 

 that the produced median frontal plate is so large that it cannot 

 be called "brevior", and that the inner marginal keel of first
