proximal two very long) and a small sixth ; tibia above 8, a 

 very minute ninth, below 5 and some spinules ; tarsus above 

 4 (the distal minute) , below 3 ; the first and third spinules on 

 the lower edge of the tarsus long, the longest on the tibia, 

 i. e. the third from the proximal end, is less than the width 

 of the segment, and the longest on the femur less than the 

 height of the segment. 



Legs. — Femur of first longer than width of carapace by 

 one third of its length, that of the second a little longer than 

 width of carapace, a little shorter than the femur of the third 

 and as long as the femur and patella of the fourth ; tibia of the 

 second equal to its femur, of the third a little longer, of the 

 fourth still longer than its femur ; the second and third tibial 

 of the fourth a little longer than the protarsal and about two 

 thirds the length of the first tibial ; the second tibial half the 

 length of the third and half the distance between the lateral 

 eyes. 



Measurements in millimetres of largest specimen. — Total 

 length 17; carapace, median length 7, width 11, distance 

 between eyes 3*5. Chela: femur, length 5*2, height 2*8, 

 length of spine 1*8 ; tibia, length 8, width 3'3, length of 

 spine 2'5 ; length of tarsus 3 7. Legs: femur of first 17, of 

 second 13 - 8, of third 14 - 5, of fourth 12 ; tibia of second 13*5, 

 of third 15-5, of fourth 13. 



Loc. Colombia (Goudot coll.). 



I have seen three dried examples of this species, namely 

 the type (which is probably a male), a female with egg-sac, 

 and a smaller example, which is probably also a female. 

 The latter two differ from the type in having shorter chela? 

 and legs ; for instance, the upperside of the femur of the 

 chela is only very slightly longer than the distance between 

 the eyes, and the femur of the second leg is about as long as 

 the width of the carapace. 



Tarantula santarensis, sp. n. 



No detailed description of this species is necessary, on 

 account of the closeness of its relationship to T. pulchripes. 

 It appears to differ in the following particulars : — 



There are no definite yellow spots on the femora of the 

 legs, these segments being rather describable as ferruginous, 

 with faint fuscous patches ; so, too, with the abdomen — the 

 upperside of this region, instead of being black, with very 

 clearly defined yellowish-red rings round the black muscular 

 impressions, is in this form ferruginous, with three faintly 

 defined fuscous patches on each tergite, one being median and 

 the others lateral.
