longer than carapace ; protarsus of 4th also longer than carapace ; 

 tarsi four or five times as long as broad ; femur of the 3rd leg 

 thicker than the others ; tibia of 1st armed with two inferior spines, 

 one median and one basal ; tibia of 3rd armed with about 9 spines 

 (2Dd legs absent) : protarsi of 3rd and 4th copiously spined ; pro- 

 tarsus of 1st with an inferior median apical spine. 



Tibial spurs. Short spur straight, longer than broad, acuminate, 

 armed below with a strong spine, also beset with bristles ; long 

 spur about twice the length of the other, cylindrical, curved, 

 bristly, with a strong superior spine at its apex ; also a spine at 

 its base on the outer side. 



Palp. Femur with an internal apical spine ; tibia with an 

 external apical spine; tarsus with a double scopular pad; spine 

 of palpal organ curved forwards and inwards towards the apex, 

 which ends with a small button-shaped tip resembling that of 

 Selenocosinia lanipes but smaller. 



Measurements in millimetres. Total length 27 ; length of cara- 

 pace 11-5, width 9-5 ; length of 1st leg 41, of 3rd 34-5, of 4th 

 45-5 ; patella and tibia of 1st 14, of 3rd 10, of 4th 14. 



Loc. Sierra Leone. 



A single male example (without further history). 



The male characters of the genus Selenogyrus have been taken 

 from the example just described as S. aureus, since the latter seems 

 to me to differ from S. cceruleus in features only of specific and 

 sexual importance. In separating the two specifically, the 

 colouring of the hairy clothing of the body has been chiefly relied 

 upon. The difference in size, too, may be noted. 



Genus Miaschistopus, nov. 



(S . Carapace longer than wide, cephalic area moderately elevated ; 

 fovea deep and transverse ; tubercle close to anterior margin. Eyes 

 of anterior line a little procurved, the anterior edge of the medians 

 in front of the centre of the laterals ; medians and laterals sub- 

 equal, the long diameter of the latter excelling the diameter of the 

 medians, the short diameter less than it; distance between the 

 medians less than their diameter, but greater than their radius, and 

 a little greater than the distance between the medians and laterals ; 

 eyes of posterior line recurved, much smaller than those of anterior, 

 adjacent, the laterals slightly the larger, and separated from the 

 anterior laterals by a space almost if not quite equalling their long 

 diameter. 



Mandible armed below with an internal row of 10 teeth and a 

 few granules behind. 



Maxilla internally spinulose, scantily clothed with setae between 

 the suture and the oral fringe. 



Labium scantily spinulose apical ly. Sternum wide, subcircular, 

 nearly as wide as long ; posterior sigilla remote from the margin, 

 but the distance between them about four times as great as the
