46 SJÖSTEDTS KILIMANDJARO-MBRU EXPEDITION. 20: 3. 



The sternal shield is fused with the endopodal shields to the middle of coxa III; 

 but further backward it is distinctly demarcated from the endopodal shield III by a 

 straight line which runs from the middle of coxa III to the posterior side of coxa 

 IV, exactly on a level with the posterior margin of the genital shield, and where 

 consequently the genital, metapodal and 3"^ endopodal shields meet. The shield bears 

 the usual 3 pairs of hairs at the iisual places, but rather far from the margin. Contigiious 

 to the Square end of the postero-lateral angle of the sternal shield and bordering, inwards 

 on the genital shield, outwards on the endopodal shield, is a small, triangulär plate, the 

 metasternal shield, provided with a large bristle. The genital shield large, semicir- 

 cular, with straight posterior margin and slightly rounded lateral corners ; one pair 

 of hairs in the posterior corners. The ventri-anal shield is large and covers the 

 whole belly, except for a very narrow marginal streak. It is broader than it is long, 

 the length to the width being as 9 to 13. The anterior margin is contiguous to the 

 posterior margin of the genital shield ; the posterior half semicircular ; lateral corners 

 broad, rounded. The shield bears 8 pairs of hairs, of which 7 are similar to the 

 dorsal ones; on pair is placed at the anterior margin, 2 are lateral, 4 are placed at 

 the margin in the posterior half, one pair in the middle, one pair, short and bare, 

 on a level with the anterior margin of the anal aperture, and one terminal hair behind 

 the anus. 



The anal aperture is twice as far away from the anterior as it is from the 

 posterior margin, with raised, long and oval cribrum. 



The metapodial shields are distinctly demarcated from the posterior endo- 

 podal shields, narrow and ring-shaped. 



The Stigmata on a line between cox;e III and IV; the peritrema curves 

 first backwards and outwards in a loop which rises above the level, turns then in- 

 wards and runs close outside and along the foveola pedalis II and extends forward 

 along the foveola pedalis I and becomes dorsal in front of it. In the portion of soft 

 skin between the metapodal and ventri-anal shield there is a pair of small, rounded 

 and finely punctured plates, the inguinal shields (?); they are the orifices of a 

 large tubulär gland, which is resistent even to hot caustic potash. 



The epistoma (PL 2, fig. 13); the proximal third is broad, with concave edges, 

 provided with fine scarce teeth ; the lateral lobes long, directed straight forward and of 

 even width in their proximal half; from thence they widen gradually to the top, which is 

 very broad, Square and with only slightly concave anterior margin; the exterior angles are 

 broader than the inferior (median) ones and divided into 2 — 3 fine slips (3 on the leftlobe, 2 

 on the right one in the specimen which I have examined); the median lobe is fine 

 and slender and branches off into two, on a level with the anterior margin of the 

 lateral lobes; it is ciliated (in the specimen I have examined the cilise were not spead 

 and thus scarcely visible). 



The mandibles (PI. 3, fig. ö). Chela short and stout, the jaws of equal width; 

 the upper one slightly longer and provided with 5 teeth at regulär intervals; the ter- 

 minal one is placed a little more inwards than the next one and both thus form 

 a groove to receive the terminal tooth of the lower jaw; the 3^^ and 5'^ teeth are
