middle of the carapace, more tlian its long diameter from the 

 anterior border, its spine erect ; anterior border of carapace 

 with a series of small suberect spines, lateral border of scute 

 with a row of tubercles ; spines on the second abdominal 

 segment a little shorter than the ocular spine and a little 

 shorter than the basal distance between them ; posterior 

 segment of the scute with a series of suberect spines, those on 

 its median third the longest ; the first, second, and third free 

 abdominal terga also spined, though less strongly. 



Basal segment of mandible long, subcylindrical, slightly 

 incrassate, I'ather longer than the dorsal area of the carapacic 

 segment of the dorsal scute, armed with scattered tubercles or 

 short spines and one very long spine near the middle of its 

 dorsal surface and a shorter one nearer the base ; the second 

 segment oval; beset with setiferous bristles. 



Palpi long, rather slender ; coxae armed above with 2, 

 below with 3 tuberculiform spines ; trochanter with 1 above 

 and 3 below ; femur slender, arcuate, armed above and below 

 with short blunt spines ; patella distally incrassate, elongate, 

 armed with 1 short inferior spine and 3 long distal spines on 

 the inner side ; tibia rather shorter than the patella, armed 

 with 5 long inferior (external) spines and 3 superior (internal) 

 spines, also a few short spines on its lower surface ; tarsus 

 oval, slightly shorter than the tibia, armed with four pairs of 

 long spines, and its lower surface furnished with a median 

 denticulated crest, upon which the claw closes. 



Femur of first leg with a series of spiniform tubercles 

 below, that of the second leg similarly but less strongly 

 tubercular, of the fourth leg practically smooth ; coxa of 

 first, second, and third legs with a series of granules. 



Total length 3 millim. ; palpi about 5, fourth leg about 10. 



Loc. Hong Kong [J. C. Boivring). 



Genus Podactis, Thorell. 

 Podactis pictulus, sp. n. (PI. XII. figs. 3, Za.) 



Colour. Trunk yellowish red, ornamented with large deep 

 green patches, exhibiting an alternate or chequered pattern 

 (arrangement), mandibles and palpi a deep rich green; 

 ventral surface of abdomen mesially yellow, laterally green. 



Dorsal scute coarsely coriaceous, subgranular; from its 

 anterior border on each side arise about 5 tubercular spines, 

 the inner of which is the largest and meets and fuses with 

 the end of a spiniform apophysis, which runs forward from 

 the ocular tubercle in front of the eyes, the two forming a 

 distinct archway. In addition to the paired larger dorsal
