lU Mr. C. J. With on Chelonethi 



Coxce (fig. 2 c). — The coxse are not placed completely on 

 the same level ; the first pair covers the hindmost portion of 

 the maxillee. The first pair is almost as broad as lon^ ; the 

 second pair is a little longer and slightly enlarged distally ; 

 the third pair, the front margin of which is covered by 

 the second, is widened out distally so considerably that its 

 shape becomes almost triangular. The fourth is as broad 

 as the third is distally and is almost trapezoid ; the postero- 

 interior corner is obtuse, and the postero-exterior is rounded 

 but scarcely produced backwards as in Ideoroncus mexicanus, 

 Bks. (PI. X. fig. Ifl). 



Legs (figs. 2f-h). — The skin of the legs seems to be 

 smooth. We find more or less long, pointed, and simple 

 hairs everywhere ; a dorsal " tactile " one is placed near the 

 base of the first tarsus of the fourth pair of legs. A long 

 pointed hair, which is provided with many teeth, especially 

 downwards, on each side near base of the claws (fig. 2 h). 

 The claws are strongly curved and longer than the areola. 

 The legs are less long and slender than in /. mexicanus ; the 

 basal femoral part of the first pair of legs (fig. 1/) is three 

 times longer than high and 1'4 as long as the distal part. 

 The tibia is as long as the basal femoral part, distinctly 

 longer than the second tarsus, and only a little shorter than 

 the two tarsi together ; the distal portion of the tarsi is 

 twice as long as the basal. The femur of the fourth pair 

 (fig. 2 g) is about twice as high as long; the trochantiu 

 is almost half as long as the whole femur, with straight 

 articular membrane. The tibia is a little longer than the 

 two tarsi, of which the distal is almost twice as long as 

 the basal. 



Colour. — The hand and the tibia of the palps are reddish 

 brown ; the basal joints, maxillse, and coxse are darker or 

 paler yellowish brown ; the legs are very pale. The cephalo- 

 thorax is brownish ; the abdominal sclerites are lighter and 

 more brilliant. Some of the specimens are paler, while 

 others are darker.
