 Alexandria. 



In " Spiders of Palestine and Syria," I. c. supra, doubts are ex- 

 pressed as to its generic place. It still appears to me that it can 

 hardly be included in any hitherto characterized genus, though at 

 present I hesitate to form a new genus for its reception. It is pro- 

 bably nearer to Steatocta than to any other ; yet the very different 

 form of the cephalothorax, in both sexes, appears to preclude it from 

 that genus, to which, however, in deference to M. Eugene Simon's 

 opinion, I now provisionally relegate it, in preference to Pachygnatha.

 Adult females were found under stones near Alexandria in April

Euryopis quadrimaculata, sp. n. 



This Spider resembles the two foregoing in respect of size, general 

 form, and characters, but may be easily distinguished by a different 

 distribution of colours on the abdomen. This part in the present 

 Spider is of a deep brown-black colour marked with four elongate 

 brownish yellow spots on the upperside, one at the fore and another 

 at the hinder extremity, and another on each side, a little nearer to 

 the fore than to the hinder spot ; these lateral spots are the longest, 

 and are placed obliquely, their inner extremities nearly meeting ; the 

 underside has a pale dull yellow transverse bar just behind the genital 

 aperture, and another close in front of the spinners, the two being 

 connected, or nearly so, by a longitudinal line of the same hue. 



The palpi are short, the radial and cubital joints very short, 

 but nearly equal in length ; the digital joint is very large, and the 

 palpal bulb well developed, a strong sinuous red-brown line (indica- 

 ting, no doubt, the passage of an internal channel) may be seen on 

 the outer side ; and from the fore extremity there projects a strong, 

 pointed dark red-brown corneous process, slightly curved and pointing 

 backwards and a little outwards. An adult male and female were 

 found near Alexandria under stones.
