feature ; the inner edge of each band is clean and well defined, but 

 the outer one is ragged and joins in with spots and markings on the 

 sides ; these spots are sometimes arranged in somewhat oblique lines 

 which run backwards ; within the central space left by the two lon- 

 gitudinal bands is a longish tapering figure defined by two blackish 

 lines which converge to a point as they run backwards from the fore 

 margin of the abdomen ; this tapering figure is very similar to the 

 marking found in a similar situation almost invariably in the genus 

 Lycosa and in many other Spiders : the underside of the abdomen 

 has three longitudinal broken lines of black spots — one line along 

 the centre and a marginal one on either side. The spinners are not 

 very long ; those of the superior pair have two joints, the extreme 

 joint bent downwards ; those of the inferior pair are the strongest, 

 and are nearly as long as the former, and of a darker colour. 



The female resembles the male in colour and markings ; the genital 

 aperture is very small and nearly circular in form. 



Adults of both sexes, as well as immature examples, were found 

 among water-weeds on the banks of the stream leading from Elisha's 

 Well, near Jericho. It is a very active Spider; and in its manner 

 of running, in its form and general appearance, and in the pattern on 

 the cephalothorax and abdomen it bears a striking resemblance to 

 many Spiders of the genus Lycosa.

Adults of both sexes, as well as immature examples, were found 

 not unfrequently under stones on the plains of the Jordan near 

 Jericho. The spinners of this Spider are but two in number.

Adult and immature examples of both sexes of this fine Spider 

 were abundant in their tubular cornucopia-like webs at various 

 places in Palestine ; these webs were usually spun firmly into some 

 thick and thorny plant. The systematic position of the genus Eresus 

 has been the occasion of some difference of opinion among araneolo- 

 gists ; for myself, I cannot perceive any close affinity in the Spiders 

 which compose it to the Salticides with which it has usually been 

 placed. As it appears to me, there are strong family affinities between 

 it and Bictyna, both in general form and structure and mode of life, 

 besides the possession by each of a calamistrum on the metatarsi of 

 the fourth pair of legs and a supernumerary maxillary organ, though
