1872.] SPIDERS OF PALESTINE AND SYRIA. 297 



broken bars and markings, of which some are somewhat convergent 

 towards the normal indentation at the junction of the caput and 

 thorax. 



The eyes are large, but not greatly unequal in size ; they compose 

 two transverse parallel rows on the fore part of the caput ; the front 

 row is the shortest, its eyes are wide apart from each other and 

 seated on conspicuous black spots ; those of the foremost row are 

 equidistant from each other ; and the hind centrals are further from 

 eacli other than each is from the hind lateral on its side. 



The legs of the first and second pairs are very long, nearly six times 

 the length of the Spider itself; their relative length is 1, 2, 4, 3; 

 those of the third pair are very short, less than one- fourth of the 

 length of those of the first pair ; they are of a dull orange-yellow 

 colour banded with dusky brown, and furnished with hairs and a few 

 short spines. 



The palpi are short, of a yellow colour, and furnished with bristly 

 hairs ; the radial is much longer and more robust than the cubital 

 joint ; it is generally tumid and enlarged at its fore extremity, where 

 on its margin there are two or three long black bristles ; the digital 

 joint is not very large, and is more of the ordinary oval form than 

 that of T. extensa and others, and its convex side is towards the 

 falces : the palpal organs are well developed and rather complex ; 

 they consist of various corneous processes and spines, one of which, 

 on their inner side and immediately beneath the fore edge of the 

 radial joint, is prominent, obtuse, and terminates with several long, 

 strong, black bristles. 



The falces are of a deep reddish-brown colour, and do not extend 

 beyond the extremities of the maxillae ; they are vertical, moderately 

 strong, and very slightly divergent at their extremities. The max- 

 illcB are straight and enlarged at their extremities, and are quite, or 

 rather more than, double the length of the labium, but much shorter 

 than those of Tetragnatha extensa &c. The labiutn is somewhat 

 of a quadrate form with the apex rather rounded. The sternum is 

 of a blackish-brown colour ; the fore margin is yellow, and it is di- 

 vided by a longitudinal tapering stripe of a similar colour. 



The abdomen is oblong, of a dull yellow colour, mottled with 

 golden or silvery metallic spots on the sides as well as on the upper- 

 side, which last has a pattern on it formed by two longitudinal, 

 nearly parallel, zigzag or dentated, broken, blackish lines, while the 

 sides are marked with fine oblique striae ; the underside is dark 

 brown and has two parallel longitudinal bars running throughout its 

 length, of a pale golden-metallic hue ; the spiracular plates are large 

 and of a dull pale yellowish hue. The abdomen of the female is 

 rather enlarged and elevated about the middle of the upperside ; the 

 epigyne is peculiar, being broad, oval, oblong, and flat, rounded at 

 its extremity, and extends backwards in near proximity to the surface 

 of the abdomen. 



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

 among water-weeds near Elisha'sWell on the Jordan plains.
