out towards extremity; the second pair are a little longer and distinctly widened 

 out towards its extremity, where they are as broad as the first pair; the third pair 

 almost as long and broad as the second, but almost triangular, and lastly the fourth 

 pair, which are almost trapezoid, are not distinctly widened out and scarcely 

 broader, but a trifle longer than the preceding pair; they are twice as long as 

 broad and have the interior margin much shorter than the posterior and the angle 

 between them well marked and obtuse. The coxae Ijear everywhere rather short 

 hairs; a number of long and pointed along hindmost margin of fourth pair. 



Legs (PI. II, figs. 1 c-d; figs. 8 a-b, p. 38). — The legs are granular with scale- 

 shaped granules; hairs on dorsal side of joints except the tarsi short and blunt; 

 those, which are placed more ventrally, fairly long and pointed, increasing in length 

 towards the end; the ventral surface of the trochanter and basal portion of the femur 

 of the fourth pair of legs bear a number of very long and slender hairs. The 

 basal femoral part of the first pair of legs, which is distinctly widened out towards 

 the extremity, is about three times longer than deep, about l? longer than the tibial 

 part, and a little deeper than this. The femur of the fourth pair of legs is about 

 three times longer than deep, and almost as deep as the trochantin is long beneath. 

 The tarsi are much longer than the tibia in the first pair of legs, and distinctly 

 longer in the fourth pair of legs; the tarsal joints are of almost equal length or 

 the second joint a trifle longer. The arolium extends slightly beyond the claws. 



Colour. — The palps, maxillae and foremost part of the head are more or 

 less pronounced dark yellowish brown; remaining part of the body yellowish or 

 light yellowish brown with the exception of a darker band along front margin of 

 each tergite, which twice on each side is widened out to a darker spot, where the 

 muscular spots are found. 



Measurements. — Specimen without egg-ball. Céphalothorax 0700 (0-210 — 

 0-925); abdomen 1-736 (1-456) mm. 



Palps: trochanter 0336 (0224); femur 0840 (0-200): tibia 0-616 (0-196); hand 

 0-616 (0-336); finger 0-756 mm. 



Specimen with small egg-ball. Leg I: femur I 0350 (0130); femur II 0200 

 (0-110); tibia 0-250 (0085); tarsus I 0180(0060); tarsus II 0190 (0045) mm. 



Leg IV: femur 0590 (0190), trochantin 0-180; tibia 0-400(0-099); tarsus I 0234 

 (0-070); tarsus II 0-244 (0054) mm. 



Material. — Dr. Th. Mortensen has collected three females under stones in 

 the Island of Koh Chang in the month of January. 



Habits. — The two females out of the three carried an egg-ball beneath the 

 abdomen attached to the genital area between the fourth pair of legs; one of the 

 females was only provided with a little ball, consisting of seven small eggs, and 

 its abdomen was carried in an almost natural position. The ball, carried by the 

 other female, was big and contained twelve large embryos, with the heads directed 

 towards the interior and with the abdomen outwards, and the mother's abdomen 

 was raised and directed obliquely upwards, well removed from the ground. On
