Description, — There are fourteen pairs of claw-bearing 

 legs, each with three spinous pads on its ventral surface. 

 The proximal pad is much narrower than the others, and con- 

 tains a considerable portion of the orange pigment, while 

 the two others are dark indigo-blue in colour. The proxi- 

 mal pad also sometimes shows a tendency to break up 

 transversely into papillee, so that it is altogether much less 

 conspicuous than the other two, and in the last pair of legs 

 may be scarcely recognisable. The median pad is the 

 largest. On the fourth and fifth legs the proximal pad is 

 transversely divided into three parts, the middle part being 

 small and bearing the nephridial aperture. The foot bears 

 three large primary papillae — anterior, posterior, and dorsal 

 overhanging the pair of claws. 



The inner jaw-blade (fig. 30) has one large tooth and about 

 seven small ones. The outer blade (fig. 29) has no accessory 

 tooth. 



The ovipositor of the female (figs. 27, 31) resembles that of 

 0. oviparus, lying between the legs of the last pair and 

 bearing the genital aperture as a longitudinal slit at its apex. 

 There are no external indications of crural or other accessory 

 glands in the female. 



In the male the genital aperture also lies between the legs 

 of the last pair, and just behind it, at the base of the short 

 broad anal cone, lies a pair of small white papillae, doubtless 

 indicating the apertures of accessory glands. Whitish 

 papillae, indicating crural glands, occur on all the legs of the 

 last nine pairs, i. e. from the sixth to the fourteenth inclusive. 

 As usual they lie just distal to the nephridial aperture, 

 except in the last pair of legs, where there is apparently no 

 nephridial aperture, and the papillae lie close to the genital 

 aperture on either side. All these crural papillfe are very 

 conspicuous. 



The general coloration of the dorsal surface (fig. 2), when 

 only slightly magnified and examined as an opaque object, 

 appears to be dark grey mottled with orange, with a dark 

 median band, fifteen pairs of green spots arranged seg-
