 and furnished \\"ith narrow white stripes which radiate from the 

 fovea to this white border, the intermediate area clothed with hairs of

 mandibles black, covered with ashy-grey hairs ; legs deep red, 

 covered with ashy-grey hairs ; the naked lines on femora, patellae, 

 and tibiae very distinct ; hairs on femora and tibiae whiter than on

Carapace longer than wide, the width almost equal to the length 

 from the anterior median eye to the posterior border. Eyes as in 

 Scodra ; the length of carapace a little less than patella, tibia, and 

 tarsus of palp, a little excelling patella and tibia of 1st leg, less 

 than those of 4th leg, equal to tibia, protarsus, and half the tarsus 

 of the 3rd, less than protarsus and tarsus of 4tl^ greater than 

 those of 1st ; the width a trifle less than patella and tibia of 1st, 

 and just exceeding those of 2nd leg. 



Legs 4, 1, 2, 3, without spines, scopulate as in Scodra ; protarsus 

 of 4th longer than tibia of 4th, and as long as protarsus and half 

 the tarsus of the 1st. 



Measurements in millimetres. — Total length 30 ; length of carapace 

 16, width 14-5; length of 1st leg 42, of 4th 48, patella and tibia of 

 1st 15, of 4th 18 ; length of tibia of 4th lO-o, height 4*5. 



Loc. W. Africa {F. W. Marshall). 



A single female specimen of this interesting new spider was 

 received from this Society, to which it had been presented alive by 

 Mr. F. W. Marshall. This specimen lived for some months in the 

 Insect-house at the Society's Gardens, and was referred to by 

 Mr. A. Thomson as Scodra calieata in his report upon the Insect- 

 house for 1897 (see P. Z. S. 1898, p. 81). Though very closely 

 resembling Scodra calceata in colour, the spider was found, upon 

 closer examination after death, to be the representative of quite a 

 distinct species.
