South African Species of Penpatidce. 337 



papillae not markedly less numerous in the two pairs of dark lateral 

 stripes, but sometimes almost or quite absent from the dorsal 

 surface proper. 



Outer surface of the legs often bluish black and slightly lighter 

 than the dorsal surface of body, the papillae black, or blue-black, a 

 number of the larger ones orange-brown in the apical part. 



Ventral surface of body generally pale orange, that of the legs 

 bright orange, becoming after long immersion in spirits pallid, 

 owing to the complete extraction of the orange colour. Dark pig- 

 ment occurs on or between the papillae along the median line, in the 

 pore at the base of each leg, and often also near the posterior end of 

 the body. Many of the papillae of the ventral surface are partially 

 pigmented with black. The papillae on the under side of the head 

 are dark green. 



The under surface of the legs is either without pigment or the 

 papillae are more or less pigmented with black. Spinous pads 

 yellowish green, the proximal ones often orange, becoming pale 

 yellowish in spirits. Foot bluish grey to almost black. Claws pale 

 at the base, dark brown at the apex. 



All the yoiuuj (2 cm. in length and under) from the same locality 

 at St. James differ markedly from the adults in colour. The 

 ventral surface is almost entirely free from dark pigment, excepting 

 under the head, and generally also along the median line and in 

 the basal pores of the legs. The upper surface resembles that of 

 half our i rather than the adult capensis, for the larger papillae are 

 much more extensively, often, especially on the sides of the body, 

 entirely orange with a ring of dark pigment at the tips. The orange 

 papillae on the legs are very pronounced and numerous, resembling 

 those on the sides of the body. 



ReddisJi forms. I have also examined several adult specimens 

 from Eondebosch (F. Trcleacen) and Newlands. In one from the 

 latter place the orange-red of numerous large papillae extends over 

 their whole surface and often also round their bases, this being 

 especially the case in the lateral band just above the bases of the 

 legs. The dorsal surface thus acquires a distinct reddish hue, and 

 the lateral bands appear quite red. The legs, however, remain 

 bluish black, the orange being here confined to the apical region of 

 the larger papillae. The under surface (exclusive of the head) of 

 several of these specimens is almost devoid of dark pigment, except- 

 ing along a faint median streak and often also at the posterior end 

 of the body. A young specimen (li cm. long) from the same 

 locality resembles those from St. James.
