SPIDERS FROM SOUTH ANNAM. 287 



The front laterals are their diameter distant from their 

 median. 



The clypeus is one and a half times longer than the median 

 eye-area and perpendicular. 



The mandil)les are conical, one and a half times as long as they 

 are broad at the base ; the fangs sliort and stout. 



The lip is longer than broad, rounded anteriorly, three-fourths 

 the height of the maxilles. The latter bend over the lip and are 

 convex, not at all impressed. 



The sternum is shield-shaped, truncate anteriorly, H times as 

 long as broad, rounded at the posterior end, but not protruding 

 between the rear coxafi, which are rather wide apart. 



The abrlomen is ovate, broader in front than at the rear, 

 rounded at the sides. At the posterior end on the under side is a 

 transverse row of short spines in front of thfe spinnerets. Of 

 these the inferior are cylindrical, raised on a membranous 

 base, with a short 2nd joint. They stand close together. 

 Tlie superior are similar, but half as long and only half the 

 diameter, standing farther apart. The epigyne consists of two 

 oval depressions, their length apart, with another shallow hollow 

 above each. 



The legs are long and fine, the joints cylindrical, with a few 

 scattered hairs along the outer sides, and short weak spines on 

 all joints except the tarsal. Near the distal end of the metatarsal 

 is a thick bunch of spinous bristles. The tarsal joints of the 2nd 

 and 3rd pairs (the others broken) are three-fourths the length of 

 the metatarsal. The claws are two, with about six pectinations, 

 and spring from a short onychium. 



The measurements in millimetres are as follows: —
