brown, lateral margins, and the legs are marked with a few 

 brown spots and annuli. The falces are powerful, conical, ver- 

 tical, and armed with a few teeth on the inner surface : the 

 maxillae are straight, and somewhat enlarged and rounded at the 

 extremity. These organs are of a red-brown colour, the maxillae 

 being the paler. The lip is semicircular, and the sternum is 

 heart-shaped: both have a dark-brown hue, the lip being the 

 darker. The eyes, which are nearly equal in size, are seated 

 on black spots on the anterior part of the cephalothorax ; the 

 four intermediate ones form a square, the two anterior ones 

 being placed on a tubercle, and those of each lateral pair are 

 seated obliquely on a tubercle, and are contiguous. The abdo- 

 men is short, broad, ovate, convex above, and projects over the 

 base of the cephalothorax ; it is thinly clothed with hairs, and 

 has on the upper part a large and somewhat oval figure, with 

 sinuous margins bordered with black, the two posterior lobes of 

 which are the most prominent ; it is of a dark greyish-brown 

 colour, densely freckled with minute white spots ; the undula- 

 tions of the black margins are followed by an imperfectly-defined 

 whitish band; and a white spot, whose posterior extremity is 

 somewhat bifid, occurs in the medial line of the anterior part of 

 the large oval figure; the sides and a broad space above the 

 spinners are of a greyish-brown colour, thickly freckled with 

 dull white, a brownish-black band extending along the anterior 

 part of the former, and a fine streak of the same hue occupying 

 the medial line of the latter ; the under part has a greyish-brown 

 hue freckled with dull white ; a broad brown-black band, bor- 

 dered laterally with white and freckled with yellowish white, 

 extends along the middle, and two black and white spots, dis- 

 posed alternately, are situated on each side of the spinners ; the 

 sexual organs are moderately developed, and of a dark red-brown 

 colour. 



Adult females of this species, which is remarkable in having 

 the fourth pair of legs longer than the second pair, were dis- 

 covered among herbage growing on the Fossil-bed.

The cephalothorax is moderately convex, compressed before, 

 rounded on the sides, and has an indentation in the medial line ; 

 it is clothed with hoary hairs, and of a red-brown colour, w r ith 

 an irregular black band on each side, extending from the lateral 

 eye about two-thirds of its length ; these bands are much the 

 narrowest at their anterior extremity, and each projects an an-
