is a Short finger-shaped appendage ; on the ventral side in front of the pulvillnm we 

 notice a transparent, rounded blade. 



The chela. The upper jaw is short, stylet-shaped and attains only Va of the 

 length of the lower one. It bears on the inner edge, near the base, a small, trans- 

 parent pin (this is not delineated in the figm-e). 



The lower jaw is also stylet-shaped, but comparatively narrower than the Up- 

 per one. The calcar mandibuli is very long, with flat ventral rounded dorsal side 

 and blunt edges; its distal third is bent downward and backward in an even curve, 

 widens slightly at the tip, becomes laterally flat and terminates with a sharp edge, 

 provided with a pair of exceedingly niinute hairs. 



The hypostoma (PI. 2, fig. 17) is shaped very mnch like thsbt oi Lcelaps {Lce- 

 laps) Versteegii Oudms'. 



The maxillary lobes are rather large, triangulär, soft and transparent, M'ith 

 broad base and placed almost perpendiculary ; thus surrounding both the lateral and 

 the ventral side of the inner mouthparts. 



The maxillary plates are transparent, finely fringed slips, and are very 

 difficult to disoern owing to their laying flat on the ventral side of the stout, rather 

 blunt and tongue-shaped lingua, which extends forward beyond the anterior margin of 

 the second Joint of the palps. The ventral side of the lingua is densly clothed with 

 minute, perpendicular or backwardly directed hairs. 



The maxillary palps are 5-jointed, slender; 1^' and 4*^^ Joint of equal length, 

 slightly longer than the 2"«^ and 3'"'^ which are also of equal length. First Joint flat, 

 with high ventral edge, provided with 2 hairs, dorsally bare; 2"'' Joint dorsally with 

 3, ventrally one external and one internal hair; 3'''^ Joint dorsally with 2, externally 

 with 1, internally with two hairs of which the anterior one is flat and club-shaped. 

 The 4*'^ Joint with about 10 hairs. The terminal Joint short, cylindrical, on the inner 

 side, proximally, provided with the usual, fork-shaped bristle, at the top with a dense 

 J)undle of 6 — 8 sharply pointed hairs. 



The legs short, the 1"^ and 2«'' pair thick, the bind legs slender. 



Coxa I ventrally with two long, stout and pointed bristles, one of which is 

 placed near the posterior margin on a transversal chitinous ridge, the other more 

 outAvard. Coxa II with two similar bristles at the distal end, one anteriorly, the 

 other posteriorly. Coxa III also with two bristles placed as is coxa II, but the pos- 

 terior one of which is much shorter and stouter. Coxa IV with one fine hair in the 

 middle near the distal margin. The other joints are richely provided with bristles placed 

 chiefly in two dorsal, one external, one internal and two subventral rows. The fol- 

 lowing are noteworthy: on the back of femur I and situated near the anterior mar- 

 gin, on a low tubercle, there is a long bristle directed obliquely backward; genu I with a 

 similar one dose to the posterior margin. The bristles of the exterior dorsal row of
