The abdomen is oval, straight in front, rounded, at the sides, and mode- 

 rately high. It is covered with downlying thick bristly hair, interspersed 

 with long upstanding bristles. The cribellum is divided, and stands up 

 rather high above the level of the abdomen. The spinnerets are normal. 



The measurements in millimetres are as follows : —

Stephanopis benhami, nov. sp. 



The cephalothorax is dull yellow with a darker triangular longitudinal 

 median stripe reaching from the rear row of eyes to the top of the rear slope. 

 The palpi, legs, lip and maxillse, sternum, and both sides of the abdomen 

 are about the same colour as the cephalothorax, the mandibles somewhat 

 darker. On the upper side of the abdomen are three pairs of muscle 

 spots. 



The cephalothorax is triangular, widening from less than a milUmetre 

 in front to 2| milhmetres at the posterior end, the edge of which is straight. 

 The skin is somewhat tuberculous, and thickly covered with do'wnlying flat 

 club-shaped bristles. The front part of the cephalothorax, on which Ues 

 the anterior row of eyes, is perpendicular to the remainder of the cephahc 

 part, on the top of which is the rear row of eyes. The latter is slightly 

 recm"vcd, equal and equidistant, rather more than their diameter apart. 

 The front row of eyes is strongly recurved, the laterals twice the diameter 

 of the rear eyes, reaching up to the margin of the upper surface. The small 

 median, one-third of the diameter of the latter, are their own diameter 

 apart, and lie a httle below the line joining the lower edge of the laterals. 

 They are twice their diameter from the margin of the clypeus. 



The mandibles are rather broad and straight. The lip is as broad as long, 

 truncate in front, and reaches barely half-way up the maxillae, which are 

 straight at the anterior end, and nearly touch one another over the lip. The 

 sternum is a broad oval, and the rear coxse touch one another. The palpi 

 are short and thick, thickly covered with bristly hair, and the patellar 

 joint is as long as the tibial.
