FALKLAND ISLAND SPIDERS. 47 



thirds the length, and there are four dark stripes perpendicularly 

 down each side at the rear end. Underneath, dingy dark yellow- 

 brown with thinner whitish downlying hair. 



The cephalic part of the cephalotho7-ax, which is only slightly 

 longer than broad, is convex, thick, and square anteriorly, 

 separated by a broad shallow depression from the thoracic part, 

 which is also convex and slopes evenly to the margin. 



The rear row of eyes is straight, or viewed from above slightly 

 recurved, but, owing to the curve of the headline, slightly pro- 

 curved from in front ; it lies on the front margin of the upper 

 part. From this point the forehead falls perpendicularly, so that 

 the recurved front row, two-thirds the length of the rear row, 

 looks straight forward. The laterals of each row are equal in size, 

 each on separate tubercles. The eyes of the rear row are 

 equidistant, the median slightly smaller than the lateral. The 

 front median pair are half the diameter of the side, three of their 

 diameters apail, and two of the same from their laterals. A line 

 drawn across their upper margin lies near but well below that 

 across the lower margin of the laterals. The clypeus is as broad 

 as the length of the quadrangle of median eyes, which is twice as 

 long as its breadth. 



The mandibles are conical, perpendicular, smooth at the base, 

 with patches of bristly hair across the lower end, and on the smooth 

 under side are a few scattered bristles. The fangs are short and 

 strongly curved. 



The lip is broader than long, widest at the base, narrowing to, 

 and rounded at, the anterior margin. It reaches to more than 

 half the height of the mandibles, which slope over it. These are 

 rounded anteriorly, and the outer margin curves continuously 

 to the insertion of the trochanter of the palps. 



The sternwm is convex, of a broad shield-shape, almost as 

 wide as long, trunca.te in front, and narrowing to a point pos- 

 teriorly between the not quite contiguous rear coxse. 



The abdomen is ovate, broadest two-thirds of the distance 

 from its base, where it is rounded and has a median longitudinal 

 depression. The downlying flat hairs are slightly plumose, all 

 pointing with their heads to the i-ear. 



The legs are moderately fine and even in length, the second 

 pair being only about one-fifth longer than the shortest of the 

 other three pairs, the fourth is slightly longer than the first and 

 third, but they do not vary much. The tarsal and rather thinner 

 metatarsal joints are cylindrical. There are two pairs of long 

 spines and one shorter on the under side of the tibia and meta- 

 tarsus of each leg. They are rather thickly covered with the 

 same downlying flat pointed hairs as the cephalothorax and 

 abdomen, and a few upstanding bristles, also long upstanding 

 spines. 



The scopulfe and claw-tufts on all feet are of the same type of 

 flat pointed, not spatulate, bristles, shorter and more upstanding
