1890.] NEW ARANEIDEA. 627 



short, 1, 2, 4, 3, the spines few and slender. The falces strong, 

 vertical, and prominent at their base in front. The et/es are small, 

 seated on black spots ; the four centrals form a small trapezoid a 

 little longer than broad ; the laterals not being greatly removed from 

 the centrals, seated on a small tubercle, and contiguous to each otlier. 

 The curve of the anterior row of eyes is the strongest, the curves, as 

 usual, opposed — i. e. that of the anterior row directed forwards, and 

 of the posterior backwards. 



The stenium is black-brown, furnished at its fore part with long 

 hairs. 



The abdomen is large, oblong, slightly tapering to the spinners, 

 and projects over the thorax ; it is of a uniform closely reticulated 

 silvery hue above, excepting an irregular blackish patch close to a 

 low prominence on each side near the fore extremity ; there is also a 

 slender blackish longitudinal central line, emitting a fine black cross- 

 line in front, still finer oblique lines on each side of the hinder 

 half, and two black elongate patches at the posterior extremity, near 

 together and converging to the spinners. The sides of the abdomen, 

 the hinder part of which projects well over the spinners, are blackish, 

 obliquely streaked with silver ; the underside has a large central, 

 uniform, silver area, parallel on the sides, square before, and rounded 

 behind. The spinners are encircled with four round silvery spots, 

 the anterior pair being the largest and widest apart. 



This Spider, though much resembling some species from Ceylon 

 and South America, is, I think, new to science. 



Hah. S. Africa. 



Genus Tetragnatha. 

 Tetragnatha taylori, sp. n. (Plate LIII. fig. 7.) 



Adult female, length 5 lines. Length of the falces over 2 lines, 

 and exceeding in length that of the cephalothorax. 



This Spider is of the ordinary T. extensa form, but the falces are 

 very divergent, and project more in the same plane with the cephalo- 

 thorax than in that species. The fang is very long and strong, 

 bicurvate, with a slight projecting point in the middle on the inner 

 side, and abruptly bent at the base close to its articulation with the 

 falx, and has a small tooth there on the outer side. On each side of 

 this articulation the falx has a strong sharp tooth ; that on the under 

 (and outer) side is much the strongest and close to the articulation. 

 The inner side of the falx is armed (next to the fang) with two strong 

 teeth placed transversely ; these are followed by two converging 

 longitudinal closely-set rows of other teeth, which decrease in size 

 towards the base of the falx ; the inner row being the shortest, but 

 its teeth the strongest. 



The legs are long — 1, 4, 2, 3 ; the spines few and slender. 



The eyes are placed in two transverse, almost concentric, curved 

 rows ; the interval between the laterals being nearly equal to that 

 which separates the central pairs. The four central eyes form a 

 square whose anterior side is rather the shortest ; and those of the 

 hind central pair are slightly nearer together than each is to the 

 hind lateral eye on its side. The clypeus is vertical, and its height
