5/4 REV. O. P. CAMBRIDGE ON EGYPTIAN SPIDERS. [June 20, 



tively enormous and perfectly globular semidiaphanous dull orange- 

 yellow bulb, with a small twisted process at its anterior extremity. 



The f alces are long, strong, divergent, and excavated towards their 

 fore extremities on the inner sides, where they are also armed with 

 two sharp strongish teeth ; their colour is similar to that of the 

 cepbalothorax. 



The maxillae, labium, and sternum are of normal character, and of 

 a dark yellow-brown colour. 



The abdomen is of a short oval form, considerably convex above, 

 but not nearly globular, and projects well over the base of the cepba- 

 lothorax ; it is of a dark yellowish brown colour mixed with blackish 

 patcbes and markings above, and sprinkled thickly, both above and 

 on the sides, with resplendent silvery markings and spots. Tbese 

 are generally gathered into a large, but not very long, longitudinal 

 band or patch on each side of the fore half, the rest being more or 

 less irregularly scattered, though in some examples they may be 

 traced somewhat more regularly in transverse lines. 



Tbe female is rather larger than the male, and her abdomen is 

 much more nearly globular in form ; but in respect of colours and 

 markings, the sexes are, as nearly as possible, similar to each other. 



Two adults of each sex were found on rushes and other plants in 

 a marsh near Alexandria. 



Although much smaller than any yet known species of this genus, 

 it surpasses all of them in beauty ; the silvery spangled abdomen 

 and enormous palpal bulb will serve to distinguish it at a glance. 



Fam. Epeirides. 

 Gen. Tetragnatha, Latr. 

 Tetragnatha molesta. 



Tetragnatha molesta, Cambr. Spid. Palest. & Syr., P. Z. S. 1872, 

 p. 295. 



Three adult males of this Spider were found among rushes in a 

 marsh near Alexandria. 



Tetragnatha nitens. 



Evgnatha nitens, Sav. et Aud. Egypte, p. 118, pi. ii. fig. 2. 



An adult female, of what I believe to be this species, was found on 

 rushes in a marsh near Alexandria. 



The fangs of the falces are very remarkable, being strongly and 

 rather abruptly bent not far from the middle, with a strong conical 

 protuberance, or tooth, on the hinder side between the bend and 

 the articulation with the falx. 



Tetragnatha flava. 



Uloborusjlavus, Sav. et Aud. Egypte, p. 117, pi. ii. fig. 1. 



An immature example of this Spider was found in the same situa- 

 tion near Alexandria as the last two species. The position of the 

 eyes misled Audouin as to its generic affinity, which is undoubtedly 

 with Tetragnatha.
