296 REV. O. P. CAMBRIDGE ON THE [Feb. 20, 



thorax is slightly suffused with dusky, and has a clear, pale, narrow 

 margin. 



An adult male was found on low plants near the stream running 

 through the plains of the Jordan from Elisha's "Well, and another in 

 a similar situation near Beirut. 



Tetragnatha minitabunda, sp. nov. 



Male adult. 



In size and general form this species also nearly resembles T. 

 extensa ; its cephalothorax, however, is shorter and broader in front, 

 and is of a dark yellow-brown colour with a broad marginal band 

 of a lighter bue, and well defined by a kind of zijzag, irregu- 

 lar, dull orange-yellow line. The eyes are very conspicuous from 

 the black spots on- which they are seated, and the length of the 

 transverse space they occupy ; each fore lateral eye is very minute 

 and seated near, but not quite contiguous to, the hind lateral. 

 The falces have the normal double row of teeth on their inner sides ; 

 but the upper row is deficient, several teeth being absent from near 

 the fore extremity of the row ; at the upperside of the fore extre- 

 mity of each of the falces is a stronger tooth than any one of those 

 in the above two rows ; the tooth is pointed, tapering, directed for- 

 wards, and has the slightest possible approach to being bifid at its 

 extremity ; close to its base on the inner side is another and much 

 smaller tooth. 



The abdomen is corrugated along its outer margins. The palpi 

 are shorter than in T. molesta ; and the palpal organs vary a little, 

 though in general form and structure their resemblance to those of 

 that species, as well as to those of T. extensa, is very remarkable ; 

 the dentition, however, of the falces, joined to the form, colour, and 

 markings of the cephalothorax, and the position of the fore lateral 

 eyes readily distinguish it from both. 



This Spider was found among plants in a moist place between 

 Hasbeiya and Damascus. 



Tetragnatha perlongipes, sp. nov. 



Male adult, length If line ; length of a leg of first pair 10^ lines, 

 length of a leg of the third pair 2| lines, length of a leg of the fourth 

 pair 4 lines. 



This species differs from all the European species of Tetrugnatha, 

 as well as from the two foregoing, in the far less development of the 

 falces and in the shorter maxillae ; the character also of the palpal 

 organs is different. In some respects it approaches near to the 

 group of exotic species, of which T. decora, Bl. (gen. Meta, 

 Koch ?), found in India and Ceylon, is an example ; but, on the 

 whole, I imagine that it may become eventually the type of a new 

 genus. 



The cephalothorax is rounded behind and compressed laterally 

 before ; it is yellow in colour, with a broad, central, longitudinal, 

 dark, dusky brown band, as wide in front as the length of the hinder 

 row of eyes, and nearly pointed behind; this band is composed of
