FALKLAND ISLAND SPIDERS. 43 



is dark yellow-brown, with a narrow darker brown median longi- 

 tudinal sti'ipe in the anterior portion, and a dark brown marginal 

 stripe ; the downlying hairs are yellowish grey, with a few 

 longer upstanding brown hairs over the postei^ior part. 



The mandibles are black-brown, with upstanding grey hairs 

 along the inner side. The fangs black- brown at the base, become 

 bright red towards the anterior end. The lip and maxillae are 

 yellow-brown with paler edges, brown hairs on these and the 

 sternum, which is much darker, almost black-brown. 



At the base of the abdomen, on the upper side, are tw^o pale 

 yellow areas divided by a longitudinal brown median streak, and 

 bounded by brown at the sides and right in front. The median 

 streak I'eaches to about halfwaj^ where it spreads out into three 

 chevrons followed posteriorly by a uniformly mottled brown area. 

 It is thinly covered all over with yellow-grey downlying hair 

 and bi'own upstanding bi'istles. 



On the under side a darkly mottled wedge-shaped area broadest 

 in front extends the whole distance from the base to the 

 spinnerets ; this is bounded by pale yellow-brown which extends 

 to the dark brown sides. 



Legs and palpi dingy yellow, with dark grey hairs and spines. 

 The cephalothorax is longer than broad, convex, straight in 

 front, slightly rounded at the sides, with no side depressions but 

 a quite short median longitudinal fovea at the upper part of the 

 rear slope. 



Eyes. The rear row of eyes is slightly procurved ; they are 

 about equal in size. The median are two diameters apart and one 

 diameter fi'om their respective laterals. The front row is shorter 

 and straight. The lateials are as large as the rear eyes and 

 slightly more than their diameter therefrom; the median, two- 

 thirds the diameter of the laterals, are their own diameter apart 

 and one-half of the same from the side eyes. The area covered 

 by the four median eyes is broader than long. 

 The clypeus is as broad as the front side eyes. 

 The mandibles, rather stout and broad, are kneed at the base, 

 thence descending perpendicularly. Fangs rather long and strong. 

 Two teeth on the inner margin of the falx-sheath, and one longer 

 between two small on the outer margin. 



The tnaxillce are upright, straight on the inner side, broadest 

 at the upper margin, thence curving inwards to the inseition of 

 the palpi. There is a long tuft of bristles on the upper part 

 of the truncature followed by shorter bristles to the lower end 

 of same. 



The lip is rather longer than broad and more than half the 

 length of the maxilla. It is narrowed at the base, just above 

 which it is widest, narrowing to a slightly hollowed truncate 

 anterior end. 



The stermmiis convex, 1| times longer than broad, straight 

 in fi-ont, whence it widens out to the middle and then again 

 narrows to a point between the not quite contiguous rear coxcT,
