which generally follow the linear direction of the several blotches ; 

 the underside is deep brown, faintly marked with longitudinal lines 

 of yellowish spots ; in immature examples the underside is yellow. 



Adult and immature males were found near Jericho and also at 

 Beirut. In 1864 it was found abundantly near Cairo, Egypt ; and I 

 have received numerous examples from Major Julian Hobson from 

 Bombay. 



Genus Ctenus (Walck.). 



Ctenus syriacus, sp. nov. 



Female immature, length 2 lines. 



The cephalothorax is of the ordinary Lycosiform shape, though 

 rather flat and level in the profile-line of its upper surface ; it is of 

 a dull orange-yellow colour, with a broadish irregular margin and 

 two broad longitudinal bands of brown, leaving a narrow yellow 

 central band, with a still narrower lateral one of the same colour on 

 either side. Across all these bands the directions of the normal 

 indentations are indicated by darker lines. 



The eyes are very unequal in size ; four large dark-coloured ones 

 form a strongly curved row on the upper fore margin of the caput, 

 the curve being directed forwards ; very close in front of, but not 

 quite contiguous to, each lateral eye is a much smaller whitish-co- 

 loured one ; and in front of each of the two centrals, close to the 

 margin of the clypeus, is another small eye ; these last two forming 

 with the centrals of the curved row a quadrilateral figure, whose 

 fore side is much the shortest. 



The legs are strong and moderately long ; they are of a yellow 

 colour, and are furnished with hairs and spines, some of these last 

 forming a well-defined double series on the undersides of the tibiae 

 and metatarsi of the first and second pairs. The palpi are similar 

 to the legs in colour. The falces, maxillae, labium, and sternum are 

 also of the same colour, the falces being marked irregularly in front 

 with dusky brownish markings. 



The abdomen is of an oblong-oval form, and its colours are yellow 

 and brownish black, forming the following very distinctly defined 

 pattern : — a broad longitudinal, central, strongly dentated yellow 

 band, having the appearance of a series of united triangles, each 

 truncated at its vertex ; within the fore part of this band are two 

 indistinctly defined blackish longitudinal lines converging to a point 

 backwards ; the sides are marked with alternate narrow dentated 

 oblique blackish and yellow stripes ; the underside is yellow, with a 

 few small irregular blackish spots or markings near the margins. 



A single example was found on the plains of the Jordan. The 

 occurrence of this Spider in Palestine is interesting, as being one of 

 the few proofs of an approach to tropical forms of Araneidea. 



Genus Dolomedes (Latr.). 



Dc-LOMEDES CONSOCITJS, Sp. nOV. 



Male and female adult, length from 5 to 6 lines.
