femur has at the distal end at the limit between the iipper 

 and the posterior side a group which on the second leg con- 

 tains ten, on the fourth leg only six longitudinal stripes; 

 besides three longitudinal stripes are spread along the dorsal 

 surface at least on the second leg. Patella and me tatarsus 

 ha ve each several scattered stripes and a group of two or 

 three longitudinal stripes near each other at the distal end; 

 tibia has a single stripe on the front side and along the dorsal 

 surface three or four longitudinal stripes. First tarsal joint 

 of the fourth leg has two, of the second leg one dorsal longi- 

 tudinal stripe, second tarsal joint is without any stripe, and 

 third joint has one single dorsal longitudinal stripe. — The 

 legs of the first pair resemble the posterior pairs to a certain 

 degree; the more essential differences shall be noted. The 

 coxa has instead of the group named only three longitudinal 

 stripes, two of which close together, and one transverse stripe; 

 the trochanter has twelve stripes in its group; on the femur 

 the group contains only four stripes, but this joint has 

 besides two transverse and ten longitudinal stripes, all scattered; 

 the tarsus is without stripes. 



In 1893 Hansen (1. c, p. 168—173) published a detailed 

 description of the lyriform organs in Thelyphonus sepiaris 

 Butl. (Th. indicus Stol.). When we compare this account of 

 the organs in a representative for the Oxopoei with that given 

 here of Schizomus Simonis, a number of minor differences is 

 observed, but the conformity as to the occurrence of groups 

 of stripes and of scattered stripes is yet widely greater be- 

 tween the Oxopoei and Tartarides than between one of these 

 groups and Amblypygi; yet it may be added that the Am- 

 blypygi not only in other features but also as to the distri- 

 bution of the lyriform organs are more related to the Uropygi 

 than to any other division or order of Arachnida. As features 

 characterizing the Uropygi we can point out that the stripes 

 occur on nearly the entire body and on nearly all divisions 

 of the appendages, at mos t wanting on the tarsi, on the claw- 

 shaped terminal joint of the antennae and on the claw of the 

 mandibular palps; furthermore at most one really compound 

 organ — consisting of regularly arranged stripes — is met 

 with, viz. at the end of the metatarsus of the three posterior 

 pairs of legs in Oxopoei but not in Tartarides, while an 

 irregular group of stripes is found on the trochanter of the
