buffonii (Savign.) and T. hirtus (Koch) ; but it may be distinguished 

 at once from the former by its longer legs, more thinly disposed 

 bristly armature, and also by the genua and fore extremities of the 

 tibiae and metatarsi of the first and second pairs of legs being of a 

 bright brownish red colour. From both these species it may be di- 

 stinguished by the structure of the palpi : in the present species the 

 radial joint, which is stouter than the cubital, has two long strong 

 apophyses from its extremity ; one, on the outer side, widens and is 

 bifid at its extremity ; the other, beneath, is simple but broader and 

 rounded at its extreme point : the palpal organs are simple and have 

 a long strong black spine coiled round them ; the digital joint is 

 angularly prominent or pointed on the middle of the outer margin. 



The cephalothorax is yellow narrowly margined with white, and has 

 two longitudinal reddish yellow-brown bands, between which, along 

 its central line, is a white bar or line ; these colours are not very 

 strongly defined. 



The abdomen is whitish mixed with yellow, and with two indistmct 

 longitudinal bands of a brownish-yellow colour along its upperside ; 

 in some examples these are broken into spots or patches ; the sides 

 are longitudinally rugose, and the prominent portions of the wrinkled 

 surface are shown by white lines. The abdomen of T. buffonii in all 

 the examples met with was unicolorous. 



Of the present distinct and interesting species three adult males 

 were found on the ground in barren places near the sea at Beirut. 

 The peculiar clothing of long pale spines and bristles affords an evident 

 protection to this and the preceding species, making them look 

 exactly like bits of coarse fleecy wool, or the rough seeds of some 

 plant or other ; had I not observed them moving, they would pro- 

 bably have escaped notice.

Adults of both sexes were found among weeds and rubbish on the 

 banks of the stream running through the plains of the Jordan from 

 Elisha's Well. The males are exceedingly active.

An adult male, and females both adult and immature, were found 

 on plants and flowers at Jerusalem.

In general appearance, structure, and colour the male of this Spider 

 nearly resembles that of T. abbreviatus (Walck.) ; the legs, however, 

 are not nearly so long, and it may at once be distinguished by the
