sulcated, hairy at the sides ; cephalothorax broader than long, with 

 a small central projection in front, so that its anterior margin is 

 ' — . — '-shaped ; a broad gradually formed transverse ridge almost 

 uniting the three oculiferous tubercles ; the central oculiferous 

 tubercle forming a transverse oval, with a central longitudinal de- 

 pression, its highest point just within the eyes, and the uppermost 

 surface of the eyes themselves flattened (as if filed smooth), the an- 

 terior pair of eyes much nearer to each other than the posterior 

 pair ; lateral oculiferous tubercles standing out obliquely from the 

 antero-lateral angles of the cephalothorax, the eyes much smaller 

 than those of the central group ; a long cylindrical process emitted 

 from each side of the cephalothorax at its postero-lateral angles and 

 parallel to the lateral oculiferous tubercles ; two widely separated 

 conical tubercles standing perpendicularly upon the posterior border 

 of the cephalothorax : abdomen irregularly subscutiform, with two 

 terminal tubercles, between which it is sinuated ; anterior margin 

 with six conical tubercles, followed by a large unequally bidentate 

 process on each side, these processes being widely divergent and 

 oblique ; a very minute tubercle on a bare spot between them ; 

 second superior abdominal fold with an acute conical tubercle on 

 each side ; pectoral shield heptagonal, its margins swollen. 



Length 16 millims., including cephalothorax, of abdomen alone 

 12, width at widest part 15 ; length of lateral odontoid processes 6, 

 width from tip to tip of processes 15 ; relative length of legs 1, 2,4, 3. 



Fianarantsoa, Madagascar. Type in Coll. B. M. 



Readily distinguished from O. mitralis by the much more promi- 

 nent, more unequally bidentate, and far more divergent odontoid 

 processes on the abdomen, the almost entire absence of the large 

 central conical tubercle, the different arrangement of the tubercles 

 on the margins of the abdomen, and the absence of bands on the 

 upper surface of the legs.
