Distance between the gonopods mncli larofer tliaii in the 

 preceding- sjiecies. Coxa? and traclieal stalk of tlie usual t'oi'ni. 

 Femoral part of tlie telopodit very distant. 'I'ibia much con- 

 densed and enlarged, showing a rounded lap (PI. xv., k. tig. 21) 

 hanging down on the outer surface of the femur. The telepodit 

 (PI. XV., figs. 21 and 22) is deepl}^ split into two branches of 

 unequal length. The outer, tibial branch (tl>.), the longest, is 

 wide, hollowed at the base, with coiled margin ; it is curved 

 inwai'ds at its distal third, and thins out in a conspicuous long 

 horn the end of whicli is bent onwards ; it furnishes a thin 

 awl-shaped process in the middle of its anterior edge (h) and 

 a short and acute triangular piece at the base of the distal 

 horn (c). Inner seminal branch (sh.) short and more slender ; 

 its base rests in the concavity of the tibial branch ; it is curved 

 inwards at its distal thirds ; the end is lamellar and divided 

 into rounded lobes at the side of which opens the seminal duct.
