1873.] SPIDERS FROM ST. HELENA. 221 



1, 2, 4, 3 ; their colour is yellow, distinctly banded with dark 

 yellow-brown, and furnisbed sparingly with hairs and a few, neither 

 very long nor strong, black spines. 



The palpi are short and not very strong. The radial joint is 

 double the length of tbe cubital, and of a clavate form, rather more 

 produced at its extremity on the upper than on the lower side ; at the 

 outer extremity a little in front is a long, curved, strong, tapering, 

 black bristle, directed forwards and nearly in connexion with a group 

 of a few less conspicuous bristly hairs. The cubital joint also has a 

 tapering black bristle at the fore extremity of the upperside, but it 

 is not nearly so strong a one as that on the radial joint ; the digital 

 joint is small but of the same length as the radial, and of a tapering, 

 pointed oval form. The palpal organs are well developed, rather 

 complex, with various corneous processes and prominently turned 

 outwards; one small, red-brown, rather flattened but abruptly pointed 

 process, separate from the general mass, appears to issue from the 

 radial joint nearly beneath the bristle and group of hairs above 

 mentioned. The palpi are similar in colour and markings to the 

 legs. 



The falces are of a dark yellow-brown colour, rather long, strong, 

 divergent at their extremities, and convexly prominent and massive 

 towards their base in front : on the inner margin of the lower side 

 at the extremity of each is a row of short teeth ; and also towards 

 the extremity of the inner margin of the upperside is a strong tooth- 

 like prominence, divided into three small points at its extremity ; 

 two of these points are stronger than the other, and from some points 

 of view are the only ones visible, the third being placed beneath and 

 a little below the others ; following this tooth-like prominence in an 

 oblique direction downwards are several small bluntish teeth of 

 different sizes. The fangs are strong, and somewhat incrassated to- 

 wards their articulation with the falces. 



The maxilla are rather long and strong, not inclined to the 

 labium, and rather broadest at their extremities, where they are 

 slightly rounded on the outer sides. 



The labium is short, broad, and semicircular, and with the maxillae 

 of a dark yellowish-brown colour. 



The abdomen is oval, not very convex above, nor much projecting 

 over the base of the cephalothorax ; it is marked with black mark- 

 ings and white cretaceous spots on a dull whitey-brown ground ; the 

 pattern is indistinct, but some angular bars or chevrons (running 

 into blotches at their extremities) are visible on the hinder half of 

 the upperside ; the sides have a large black patch forwards, followed 

 behind by several slightly oblique black bars more or less distinct ; 

 along the underside runs a broad black-brown baud, occupying 

 nearly the whole of it. 



The female is larger than the male, to which it is similar in colour 

 and markings, but differs in wanting the large trifid and other 

 teeth on the front of the falces, having only one row along the inner 

 margin of the lower side ; these, however, are more numerous, 

 longer, stronger, and sharper than the corresponding teeth in the
