Of this tribe of Ihe order Pedipal|)i six immature specimens are to band ; they 

 were taken togetber and belong to tbe same species. Of tbe Tartarides only one species, 

 Trithyreus africanus H. J. H., is known from Africa — it was taken at Freetown in 

 tropical West Africa; 0. F. Cook, bowever, mentioned Artacarus lihenensis from Liberia, 

 but in 1905 I proved tbat this genus must he cancelled and the species considered as 

 a nomen nuduni. The species brought home by Professor Y. Sjöstedt from tbe Kili- 

 mandjaro belongs to tbe genus ScMzornus Cook as defined in the monograph written by 

 H. J. Hansen & W. Sörensen^; it is new to science, but immature specimens of tbe pre- 

 sent tribe bave tbe specific cbaracters much less developed tban the adults, and especi- 

 ally the shape of the flagelkim in immature males is nearly wortbless, while in tbe 

 adult males tiie flagellum shows the best cbaracters. \^ 



In spite of such difficulties I establisb a new species on the specimens to band, 

 tbinking tbat especially by aid of the iigures it may be possible to recognize tbe adults, 

 wben tliey liave been captured hy a future investigator.
