CHELIFERID^ AND GARYPID/E IN THE BRITISH MUSEUM. 65 



long as the finger ; it differs by the shorter tibial stalk and by the hand, which 

 is almost as deep as the finger is long. From Chelifer articulosus, Sim., it 

 differs by the more slender femur ; from Ch. rotundus, With, to which it in 

 most respects shows very great similarity, by the less distinct granulation 

 of the palps, by the femur (which is much more slender, being 2-2 instead of 

 2 as long as wide), by the tibia (which has a shorter stalk and less strongly 

 convex outlines), as well as by a few other characters of minor value. They 

 are perhaps male and female of the same species ; at the present, however, I 

 prefer to found a new species. 



C. Species from Africa. 



The CheUfer-la.im?i of Tropical Africa has until lately been very imperfectly 

 known ; a recently published paper by ElHngsen (17) has vastly increased 

 our knowledge by adding a number of new species to those already known, 

 but not so many as might have been expected from the large number of 

 specimens examined. It may nevertheless be regarded as certain that the 

 greatest number has not yet been described. All the main groups of Chelifer^ 

 Geoffroy, seem to be present ; however, representatives of LbpJiochernes, 

 Simon, are with certainty only recorded from Socotra, viz. Ch. socotrensis. 

 With, and from Natal^ viz. Ch. sculpturatics, Lew. In the British Museum 

 collections only a single species in addition to Ch. equester, With, was 

 represented, viz. Ch. Shnoni, Balzan, aboiit which the following remarks are 

 offered. . j

Palps. — The trochanter is scarcely produced below and posteriorly, only 

 convex. T\\q hand is as wide as deep; the fingers gape slightly, have no 

 accessory teeth, and anteriorly three basal " spots " on immovable finger, none 

 on movable. 



Co.vcB. — The fourth pair, which are distinctly enlarged towards the end and 

 much longer than wide, have an elongated and triangular appearance, as the 

 short inner margin merges gradually into the about four times longer hinder. 



Legs. — The proximal joints are granular. The rather short hairs are 

 dorsally slightly clavate or obtuse ; tarsal " tactile " hair was missing in 

 examined specimen. The legs are long and slender, and the trochantin of 

 the first pair of legs has a structure similar to that of Ch. suhruber, Simon 

 (c/. 18. figs. 5a-6, p. 37), and Ch. rufus, Balzan {cf 19. figs. '6d-e). The 

 trochantin has anteriorly a small median condylus, from which the narrow- 

 articulate membrane starts, becoming broader dorsally and ventrally ; poste- 

 riorly a small condylus is placed near to the dorsal margin, and below this.
