o/' the céphalothorax and almost half as broad; their chelae interiorly with small 

 spines; hairs of flagellurn in a simjle Infi. Lamina niaxillaris superior widened out 

 dislallfi, rounded and murginallii dentaled. The tibia of the palps only half as tony 

 as the femur; the hand is distinctly longer and broader than the tibia, but shorter 

 than the fingers, which bear about 20 rather small marginal teeth. Hand with a 

 dorsal pair of tactile hairs, placed slightly nearer to the base than to the middle. 



?. Céphalothorax (fig. 1 a). The two pair of well developed eyes, of 

 which the anterior pair is the more lateral, are removed Iroin each other as well 

 as from Ihe front margin a distance about as long as their diameter (fig. 1 a). The 



céphalothorax is gradually widened out towards 

 the first pair of eyes; but it becomes in front 

 of this narrower again; behind il is not as broad 

 as long, bul il is behind the lirsl pair of eyes, 

 where the greatest breadth is I'ound, much bi'oader 

 than long. The fronl margin is almost slraighl, 

 but has in the middle a minute, rather blunl and 

 slightly dentaled eminence, on each side of which 

 a long pointed hair is articulated on a moderate 

 elevation (fig. 10). The céphalothorax is almost 

 smooth and bears, at least in front, a few longer or 

 shorter moderately slender hairs. 

 Abdomen. — The abdomen is about twice as long as the céphalothorax and 

 of almost equal breadth; it is narrower in fronl than farther behind. Each tergite 

 is at least laterally provided with a j)ointed, rather long and thick curved hair; 

 the last sternites bear several shorter and longer hairs; the eleventh sternile bears 

 a pair of "tactile" hairs. The genital openingÇ?) is rhombic and backwards 

 limited by two chitinous ridges, which together establish an obtuse angle. 



Antennae (figs. 1 c-d). — The antennae are very large, being as long as two 

 thirds of the céphalothorax and almost half as broad. Their interior margin is 

 convex proximally and terminally, but concave in the middle; the exterior margin 

 has a proximal convexity passing gradually over in a distal concavity. The hand 

 bears a few long pointed hairs and is inwards armed with a number of rather 

 big spines (fig. 1 a and 1 c). The immovable finger is terminated with a moderate 

 hook, and bears behind this a small tooth, which is followed by a row of about 

 ten teeth, decreasing backwards (fig. 1 c). The inner margin of the movable linger 

 bears about 14 teeth between the tip and the insertion of the serrula exterior 

 (fig. 1 d, m). The galea is represented by an exterior, fairly well marked protube- 

 rance. The flagelluni (fig. 1 c, /') consists of Iwo (three) lui'ls(?) of hairs; all the 

 hairs are pointed, plumose and enlarged at their base; the first group contains 

 only a single hair, distinctly curved backwards; the second group consists of six 

 longer or shorter, more or less branched hairs, the basal swollen part of which 

 is placed within an oval, smooth common articulate area, surrounded by finely
