1872.] BPIDERS Or PALESTINE AND SYRIA. 321 



In size, form, and colours this Spider resembles D. mirabilis 

 (Clerck), from which the chief and most tangible distinctive cha- 

 racter that I have been able to detect in the preserved specimens is 

 the formation of the radial joints of the palpi ( d ). In D. mirabilis 

 the radial joint has at its outer extremity a small apophysis gradually 

 tapering to a fine and somewhat crooked point ; in the present spe- 

 cies this apophysis is replaced by one longer, and broad throughout 

 the greater part of its length, when it rather abruptly goes off into 

 a fine curved point ; the form of the genital aperture in the female 

 is also slightly but distinctly and constantly different from that of 

 the female of D. mirabilis. In respect of colour and markings, 

 there seems to be a similar and as great variety as in that species. 



An adult male and several females were found on low-growing 

 plants on the plains of the Jordan, an adult male at the foot of the 

 Lebanon near Ain-Ata, and adult and immature females on the plain 

 of Esdraelon. Not having detected in Palestine the European form 

 D. mirabilis, it has occurred to me that that species may be replaced 

 there by the present nearly allied but distinct form.

An adult male of this fine and strikingly coloured Spider was 

 found at Kefr Menda, near Cana-el-Jelil.

 figs. 1121-1123. 



Adults of both sexes of this species were found near Ain-Ata, on 

 the skirts of the Lebanon. Although exceedingly similar to the 

 foregoing, it is yet very distinct on comparison. It appeared to be 

 a common Spider in this, the only locality in which I met with it.

Salticus cephalotes (Sim.). 



Adults and immature examples of both sexes of this brightly co- 

 loured and pretty species were found in various localities, principally 

 on the plains of the Jordan and at Jerusalem. I also met with it 

 subsequently at Corfu ; and it has been found by M. Simon in Spain. 

 It is an exceedingly active Spider.
