Pedipalpi, Ricinulei, and Opiliones. 19 



Fourth legs considerably shorter than the body; femur 

 (fig. 4 c) a little shorter than in the male, a little more than 

 twice as long as deep. 



Three posterior abdominal segments somewhat less deep 

 than in the male. 



Flagellum (fig. 4 d) even a little longer than in the male, 

 scarcely five times as long as deep, three- jointed; third joint 

 scarcely twice as long as the two proximal joints combined. 



I/ength of the body 3.15 mm., palps 1.40 mm., first leg 

 3.15 mm., fourth leg 2.77 mm. 



Remarks. T. brevicauda is closely allied to T. afri- 

 canus H. J. H., which was established (in 1905) on a probably 

 immature female from Freetown. But the specimen of T. afri- 

 canus, which was 2.9 mm. long, thus only a h'ttle smaller than 

 the adults of T. brevicauda, differs from these in having the 

 claw of the palps conspicuously shorter, and besides especially 

 in the foot which has the terminal joint proportionately much 

 longer than T. brevicauda, and though this joint is proportio- 

 nately longer in immature than in adult specimens, the diffe- 

 rence between the relative length of this joint in T. africanus 

 and T. brevicauda is so large that my adult specimens cannot 

 belong to T. africanus. It may be added that the foot of T. afri- 

 canus is nine time as long as deep, thus nearly more slender 

 than those in T. brevicauda, but in immature specimens the 

 foot is less slender than in adults of the same species. The 

 small flagellum of the male differs very considerably from that 

 organ in males of other species hitherto known. 



Occurrence. -- Bolama in Portuguese Guinea (Kerry 

 coast), December n, 1899; 3 adult specimens (i <J, 2 ?).
