Legs long, slender ; relative length 1, 4-2, 3 ; furnished sparingly with 

 hairs, and similar to the cephalothorax in colour ; in some specimens 

 they are faintly banded or clouded with dusky red-brown, particularly 

 at the extremities of the tibiae. 

 Palpi long, proportionately rather stronger than the legs, and furnished 

 with hairs ; the humeral joints are long and bent ; the cubitals long, 

 elavate, and bent forwards ; radials short, and produced on their outer 

 sides; digitals short, oval. PaZpa^ or^raras directed outwards, not very 

 complicated, consisting of some compactly fitting corneous lobes and 

 processes, and destitute of any very remarkable structural feature ; in 

 fact these parts are very similar in general appearance to the palpal 

 organs of several species of our British Theridia. 

 Falces long, strong, slightly projecting, protuberant in front, a little di- 

 vergent, and similar to the cephalothorax in colour. 

 MaxillcB long, strong, inclined towards the labium, their outer marginal 

 line slightly hollow : extremities obliquely truncate on the outer sides, 

 and the inner marginal line rounded. 

 Labium broader than high, somewhat oblong, but roundish-pointed at 

 the apex, which reaches about halfway up the maxillae ; these, with 

 the labium and sternum, are rather darker in coloiu* than the cephalo- 

 thorax . 

 Sternum of a somewhat triangular form, compressed laterally towards its 

 apex (which is directed backwards), and having by far its shortest side 

 (the base of the triangle) in front. 

 Abdomen oblong, rounded and bluff in front, a little compressed towards 

 the middle ; the hinder portion is much produced over and beyond 

 the spinners, the produced part having a bluff termination, near which, 

 on either side, is a slight prominence ; the upperside is of a pale 

 brownish-yellow colour, marked with two longitudinal silvery lines 

 which converge and form one line towards the hinder part : these lines 

 are dilated on the sides of the abdomen into two or three irregularly 

 sinuous and oblique silvery lines, strongly margined with deep red- 

 brown, approaching black. Spinners prominent, rather nearer to the 

 hinder than to the fore extremity of the abdomen. 



The female resembles the male in colours and markings ; these 

 last, however, are better defined in the former sex. In some spe- 

 cimens of both sexes the abdomen is more or less suffused with 

 silvery spots in addition to the regular lines and markings. In 

 the female the hinder extremity of the abdomen is produced in a 

 long and more or less sharp-pointed form, thus offering a strong 

 contrast to its form in the male. The spinners of the female are 

 also in general nearer to the fore than to the hinder extremity of 

 the abdomen ; her caput wants the deep fissure of that of the
