The falces are moderate in length and strongth, vertical, and 

 similar to the legs in colour ; the denticulations being very 

 minute. 



The maxillse are of a dull yellowish hue, and the labium is 

 rather darker coloured. 



The sternum is of a somewhat subtriangular form, yellow 

 along the middle, with a broad, dark yellowish brown border. 



The abdomen is very large, globular, and projects greatly 

 over the base of the cephalo-thorax. It is very thinly clothed 

 with hairs, and is of a shining silvery white colour, with a 

 golden tinge on the middle of the upper side, and clouded in 

 parts with a pale brownish claret hue, forming a definite though 

 not a very strongly marked pattern ; and the whole surface is 

 covered with an irregular network of fine dusky lines. On the 

 fore part of the upper side is a ring, formed by a band of a 

 pale claret colour ; the enclosed space bears a darkish cruciform 

 marking ; this is followed by a somewhat dagger-shaped mark- 

 ing of a similar hue, which runs into a largo quadrate dull 

 claret-coloured area; this area is rathor the palest along the 

 middle, and at the fore extremity, but reaches quite to the 

 spinners, on each side, a little above which there is a largish 

 silvery blotch, with another, smaller one, still nearer to the 

 spinners. Tho sides are marked with a strong, oblique, claret- 

 coloured stripe or band. The under side is reddish-brown. The 

 spinners are short and compact, the four outer ones equal in 

 length. The gonital aperture is rather large, of a transverse 

 somewhat oval form, and placed behind a strong, shining, black 

 prominence. 



A single example of this very pretty and distinct littlo spider 

 was found among low herbage on the edge of a watery swamp 

 noar Bloxworth on the 30th of June, 1879. It is closely allied 

 to Thcridion gcmmosum, L. Koch, but on comparison with types 

 of that spider received from Dr. L. Koch I think it is of a 

 distinct species. The colouring and pattern are different ; the 

 tibia) of the first pair of legs appear to be rather longer and
