292 Mr. R. I. Pocock on the Pedipalpi of the Family 



the smallest. Tibia with the customary upper and lower 

 longitudinal crest of granules, the lower and anterior surface 

 weakly and sparsely granular ; in addition to tlie three normal 

 long distal spines, the upper edge is furnished with two or 

 three smaller spines evenly spaced and decreasing in size 

 posteriorly, the posterior one being always minuta and some- 

 times scarcely recognizable amongst the rest of the spinules ; 

 the first of the three long spines about two thirds or more of 

 the length of the second, which, like the third, is serrate 

 anteriorly ; the inferior distal spine of normal length and 

 strength, the rest of the lower edge armed with about 4 spines 

 and many spinules. Tarsus polished, the tirst spine of the 

 upper surface about one third the length of the second. 



Legs. — Femora spieular above, below, and in front ; femur 

 of first less than twice the width of the carapace, that of the 

 second a little shorter than that of the third and a little longer 

 than that of the fourth ; tibia of second shorter than its femur, 

 that of the third a little longer, that of the fourth still longer, 

 the second tibial about equal to the distance between the 

 lateral eyes. 



Measurements in millimetres of type ( i^ ). — Total length 

 .32'5 ; carapace, width 17'5, median length 10, distance be- 

 tween eyes o'2. Chela : length of femur 27*5, of tibia 30. 

 Legs : femur of first o2'0, of second 21, of third 22, of 

 fourth 20. 



Locality of type. — Rio del Rez, near Old Calabar {H. H. 

 Jolinston) ; of other examples Old Calabar and the Cameroon 

 Mountains {H. H. Johnston) ; Fernando Po and Gaboon. 



The example selected as the type of this species is not the 

 largest. Thus a male from Old Calabar has the carapace 

 19 millim. wide, and the femora of the five appendages 

 measure respectively 35, 41, 23, 24-5, and 22 ; and the 

 largest female from theCameroons has the carapace 21 millim. 

 wide, and the femora measure respectively 33, 42, 24, 25, 

 and 23. 



The three species of this genus known to me may be 

 readily recognized by the characters given in the synoptical 

 table ; but it is not to be supposed that the distinctness of the 

 species necessarily rests solely upon those characters that are 

 mentioned in the tabular diagnosis. The above-mentioned 

 example from Fernando Po was identified by Mr. Butler as 

 P. medius, Herbst.
