or green; hands sometimes reddish-brown. Dorsal keels of the strong cauda granular. 

 Hand of maxillary palp as broad as length of movable finger, with isolated, roundish, 

 sometimes reticularly confluent, smooth prominences. The var. suhtijpicus Kraepelin 

 {Mt. Mm. Hainhurg XI. 1894 p. 69) is distinguished by the following characters : Lower 

 median keels of first and second caudal segments completely absent. Dorsal plates of 

 abdomen nearly smooth ; only 13 to 11 lamellae in ventral combs. 



This enormous scorpion, which attains a total length of 175 mm., is represented in 

 the tropical part of the Sudan (Gour country) by the above mentioned var. r:iiljtupiri(s. 

 It is well distinguished from the West African typical form.

Distinctive 

 characters 

 of the 

 Pedipalpi 



Pedip.\t,pi 



A group of curious annulated spiders, somewhat allied to the scorpions and restricted 

 to the tropical parts of both hemispheres, is represented by a single species in the Sudan. 

 From the scorpions, to which some (but not the Sudanese one) bear a superficial resemblance, 

 they are easily distinguished by the fact that the first pair of limbs is very slender 

 elongate, even flagelliform (hence the German name " Geissel-Spinnen," flagellated 

 spiders,) that there is not a cauda of five strong segments with a poison-vesicle and poison- 

 sting at the end, but a slender filiform elongate postabdomen consisting of many annuli 

 or no postabdomen whatever; and that comb-like appendices of the ventral side are 

 wholly absent. The single Sudanese species belongs to the Tribe Ainhhjpijiji, witli broad 

 reniform cephalothorax, without caudal filiform postabdomen and with elongate maxillary 

 palp, the hand of which is provided with a movable claw ; and with an extremely 

 elongate whip-like, nuilti-annulated terminal portion of the first pair of limbs. 



As far as we know, the pedipalpi are oviparous, the newly hatched young undergoing 

 no metamorphosis. They are predaceous animals like the scorpions, with about the same 

 limits of distribution, but are absent in the countries bordering the Mediterranean, as well 

 as in Australia. They live somewhat like the scorpions, but perhaps keep even more 

 concealed, some actually being found in caves.
