the projection is furnished with a short, curved, dark red-brown, cor- 

 neous point ; the humeral joint is disproportionately large and tumid ; 

 the cubital is short and strong ; the radial strong, curved, and tumid ; 

 the digital somewhat globular at its base, and produced outwards into 

 a long slightly curved projection which has several points at its extre- 

 mity. The first four of these joints are of a pale yellow colour with a 

 few slight blackish and red-brown markings at their articulations or 

 extreme edges ; the digital joint is suffused with red-brown, princi- 

 pally towards its extremity ; all the joints are furnished with a few 

 dark hairs. The palpal organs are large and highly developed, con- 

 sisting of a pale yellow, circular, basal corneous lobe, with a long, dark 

 red-brown, tortuous projection of the same nature furnished with a 

 short, strong, curved point on its outer side ; between this point and 

 its extremity this corneous projection is fringed with a closely set fringe 

 of reddish-coloured prominent hairs. 



Falces small, but strong ; conical, vertical ; furnished with hairs, and of 

 a dark yellow-brown colour. 



Maxilla rather long, somewhat pointed, and smaller at their extremities 

 than near the base ; greatly inclined towards, over, and slightly be- 

 hind the labium, their extremities being almost in contact. In colour 

 the maxillae are dark yellow-brown, paler at the extremities. 



Labium short, broad, broadest in the middle, narrowest at the base ; the 

 apex, which is somewhat rounded, is of a pale yellow colour, the re- 

 mainder being similar to that of the maxillae. 



Sternum heart-shaped ; of a pale yellow colour, with a large, central 

 dark yellow-brown patch of a somewhat similar shape, having circular 

 indentations all round its margin opposite to the articulations of the 

 legs. 



Abdomen longish, narrow, oval, abruptly and perpendicularly truncate 

 behind, where it is also rather elevated ; i. e. it does not slope, as in 

 most spiders, when looked at in profile. Its colour is a dull yellowish 

 whity-brown ; a series of three or four largish and irregularly angu- 

 lar brownish patches occupies the medial line of the upperside ; these 

 patches are all edged on the outside with a line of silvery white hairs : 

 a broad band of brown similarly edged occupies the entire medial line 

 of the underside. Spinners short, dark brown, tinged with reddish. 



The adult ? resembles the S in colour and markings. Sexual organs 

 prominent ; the aperture circular, edged with deep red-brown ; and 

 from and within the concavity issues a short, strong, dark reddish 

 brown epigyne, which curves backwards : a patch in front, and con- 

 nected with the aperture, is of a dark yellow-brown colour. 



Four adult specimens (two c? and two $ ) were contained in 

 Mr. Nietner's collection.
