C'HAMBERLIN: the ARkcHNIDA. 279 



Anterior row of eyes shorter than the second (about as 11:12); 

 sHghtly procurved; diameter of medians greater than that of laterals 

 in ratio 4:3; medians three fourths their diameter (or a little farther) 

 apart, their radius or slightly more from the laterals; median eyes 

 more than their diameter from the lower edge of the clypeus (about 

 once and a fourth), the laterals nearly once and two thirds their diam- 

 eter from it. Diameter of eyes of second row exceeding that of the 

 anterior medians in about ratio 5:2; eyes of second row more than 

 their radius apart (about three fifths diameter), less than their radius 

 from anterior medians (two fifths diameter). Posterior eyes a 

 little smaller than the second, three and a half or a little more times 

 their diameter apart. Quadrangle of posterior eyes contained in 

 total length of cephalothorax about 3.75 times. Area of median eyes 

 much wider than long (48: 34), wider behind than in front (12:5). 



Total length of sternum exceeding the width in ratio 8.5-9:7, 

 (Plate 22, fig. 8). 



Labium wider than long, (Plate 22, fig. 7). 



Upper margin of furrow of chelicera with the usual three teeth; 

 lower margin with four teeth of which the third from the distal end 

 is much the smallest, the other three stout, conical, equal, (Plate 22, 



fig. 9). , . . 



Anterior tarsi and metatarsi scopulate to base ; the posterior meta- 

 tarsi scopulate lightly on distal portion only. Tibia I with five 

 pairs of ventral spines, these being very long, the first or basal ones 

 overlapping bases of those of the third pair, the distal spines much 

 shorter than those of first and second pairs; also a short spine on 

 anterior and one on posterior face. Metatarsus I with three pairs 

 of ventral spines of which the first two pairs are very long like those 

 of the tibiae ; also with three spines on anterior and three on posterior 

 surface and a pair of dorsal ones near distal end. 



Anterior piece of lorum of pedicel notched behind, the posterior 

 piece rounded anteriorly and fitting into the notch. 



Process of tibia of palpus in male ventral in position; subcorneal 

 and low in specimen lacking one moult of maturity. 



Male. Length, 9 mm. Length of cephalothorax, 3 mm.; width, 

 2,5 mm.
