1872.] SPIDERS OF PALESTINE AND SYRIA. 233 



following these blotches are 2-3 yellow-grey transverse angular bars, 

 and a large somewhat triangular patch of the same immediately 

 above the spinners, bearing broken traces of short angular black 

 bars ; on the outer side of each of the hindermost of the six above- 

 mentioned blotches, and a little forwards, is a larger one of the same 

 colour, followed behind by another smaller one, each being produced 

 backwards in an oblique yellowish lateral line or stripe ; the under- 

 side has three parallel longitudinal blackish stripes, the central one 

 being the strongest, but tapering towards its hinder extremity. The 

 spinners are neither very long nor strong ; those of the superior and 

 inferior pairs are of equal length and strength ; the spiracular plates 

 are yellowish, and the space between them is a dark yellowish brown. 

 An adult male and an immature male and female were found at 

 Jerusalem under stones.

 fig. 445. 



An adult male of this species was found beneath a stone on the 

 shores of the sea of Galilee, -near Tiberias. The male of this species 

 is described and its palpal organs figured in ' Die Arachn. Fam. der 

 Drass.' p. 120, pi. v. figs. 75, 76, by Dr. L. Koch. 



Drassus tenerrimus, sp. nov. (Plate XV. fig. 10.) 



Male adult, length 1^ line. 



This small species has the cephalothorax and falces of a clear pale 

 yellow colour, but of ordinary form, the former showing the faintest 

 possible dusky converging lines ; the whole of the rest of the Spider 

 is a pale whitish yellow, the abdomen marked with a small, dusky, 

 central, longitudinal, pointed bar on the fore part of the upperside] 

 followed by some roundish spots of the same hue. The eyes are in 

 two transverse rows ; the foremost one (looked at from behind) is 

 nearly straight, the hinder one rather strongly curved, bringing the 

 laterals into contiguity with the laterals of the front row ; the inter- 

 val between the hind centrals is greater than that between each of 

 these and the hind lateral on its side ; the fore centrals are unusually 

 large, and convex, by far the largest of the eight, and each touches the 

 lateral on its side ; they are seated on a large and conspicuous black 

 patch, and are of a dark brown colour, the rest being pearly white 

 with black margins. The legs are long and slender ; their relative 

 length 4, 1, 2, 3, and very sparingly furnished with hairs and a few 

 fine black spines. The palpi are long and slender: the radial and 

 cubital joints are of about equal length and strength ; the former has 

 a small, red-brown, tapering, pointed apophysis at its fore extremity 

 towards the outer side. This apophysis curves very slightly upwards 

 near its point. The digital joint is large, and its fore extremity 

 rather produced ; the palpal organs are well developed and rather 

 prominent and complex, with corneous spines and processes. 



An adult male was found under a stone on the plains of the Jor- 

 dan, and another in a similar situation at Hasbeiya ; the large size 

 and colour of the fore central eyes, with the black patch on which
