remaining segments with the exception of the last olivaceous in 

 front with a dark bluish band along the posterior margin' and 

 a pair of distinct longitudinal grooves throughout, about half of 

 these segments with raised lateral margins ; last segment olivaceous, 

 little darker behind than in front, entirel}^ without paired or 

 median grooves, lateral margins very strongly raised, posterior 

 margin curved Ventral surface uniformly olivaceous or with head 

 and first segment browner or paler than the rest ; sternocoxal plate 

 armed with 5 minute and widely separated teeth, sterna of seg- 

 ments 2-19 or 20 with a pair of distinct longitudinal grooves ; 

 sternum of the last segment rather slender, narrower behind 

 than in front, posterior margin straight or very nearly so. Pseudo- 

 pleural processes conical, rather slender, the apex simply 

 pointed. Tooth on inner side of femur of poison-jaws strongly 

 developed ; first pair of legs paler in colour than the rest, legs 

 I- 1 9 armed with i tarsal and 2 claw spurs, the twentieth with 

 2 claw spurs and o(-i) tarsal spurs, the anal legs usually 

 without spurs, sometimes, however, with i claw-spur. Femur of 

 anal legs armed normally with 2,2 ventral outer, 2 ventral 

 inner, 2 dorsal inner and i long and always simply pointed 

 posterior dorsal spine • the arrangement, however, is sometimes 

 less regular than this when one or two additional spines are de- 

 veloped ; and the proximal ventral spine is often so much reduced 

 that it is not improbable that it may occasionally be absent. 

 Distal tarsus of anal leg moderately slender in young specimens ; 

 much stouter proportionally in adults in which it is sometimes 

 actually shorter than the very large claw. 



This species comes next to S. inorsitans when compared with 

 Kraepelin's table (loc. cit., pp. 226-232), but can be distinguished 

 therefrom at once by the simply pointed pseudopleural processes 

 and the similarl}^ simple posterior dorsal spine ("eckdorn") of 

 the anal legs as well as by other minor characters. 



1 Mr. Kemp informs me that the colours were much more brilliant in life, 

 the ground colour which is now olivaceous being then a straw-yellow.
