brown, and the digital joint has a dark brown tint ; the radial 

 joint is larger than the cubital, and projects from its extremity, 

 on the outer side, two bifid apophyses ; one branch of the supe- 

 rior apophysis is prominent, and the other is in close contact 

 with the base of the digital joint, which is oval, convex and 

 hairy externally, concave within, comprising the palpal organs ; 

 these organs are highly developed, complex in structure, with a 

 pointed, prominent process at their base, and have a brownish 

 black tint. The upper part of the abdomen is of a red-brown 

 colour interspersed with a few black spots; it is palest in the 

 medial line, but the design of the broad, dentated band is almost 

 obliterated ; the frontal margin and a band extending along each 

 side have a yellowish white tint, and the under part is of a pale 

 red-brown colour. 



The abdomen of both sexes, when adolescent, is of a pale yel- 

 low colour, with a few black spots on the upper part. 



Adult and immature individuals of this species of Thomisus 

 were discovered among grass growing in and near woods at Oak- 

 land in August 1852. 



Family LiNYPHiiOiE. 



Genus Linyphia, Latr. 



Linyphia Meadii. 



Length of the female ^th of an inch ; length of the cephalo- 

 thorax -j-'^ ; breadth g^, ; breadth of the abdomen ^j ; length of 

 an anterior leg ^ ; length of a leg of the third pair ^. 



Cephalo-thorax oval, convex, glossy, with slight furrows on 

 the sides converging towards the middle, and an indentation in 

 the medial line : falces powerful, conical, nearly vertical, diver- 

 gent at the extremities, and armed with teeth on the inner sur- 

 face : maxillee straight, with the exterior angle, at the extremity, 

 curvilinear : legs and palpi provided with haii'S and fine spines. 

 These parts are of a light yellow-brown colour, the legs and 

 palpi being rather the palest. Lip semicircular and prominent 

 at the apex : sternum short, broad, and heart-shaped. These 

 parts are browner than the cephalo-thorax, the margins of the 

 sternum being the darkest. The first pair of legs is the longest, 

 the second pair rather surpasses the fourth, and the third pair is 

 the shortest ; each tarsus is terminated by three claws ; the two 

 superior ones are curved and slightly pectinated, and the inferior 

 one is inflected near its base. Eyes seated on black spots ; the 

 four intermediate ones describe a trapezoid whose anterior side 

 is the shortest, and those of each lateral pair are placed obliquely 

 on a small tubercle and are nearly contiguous ; the anterior eyes 

 of the trapezoid are the smallest of the eight. Abdomen ovi-
