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



I have conferred, with great pleasure, the name of our veteran ara- 

 neologist Mr. Blackwall, was found under a stone at Jerusalem, and 

 a female, in a tubular silky web, among the loose broken earth of 

 an old bank near Beirut ; it is not certain whether the web belonged 

 to this Spider, or whether it might not have been an appropriation 

 of the labours of some other Spider. 



Pal^stina, nov. gen. 

 Characters of the genus. 



Cephalothorax oblong, slightly constricted laterally forwards, mo- 

 derately convex above ; caput large, uniformly convex and rounded, 

 without any impression of the clypeus. Normal grooves and inden- 

 tations almost obsolete. 



Eyes eight, not very unequal in size ; in two transverse slightly 

 curved rows not far removed from each other. 



Fakes short, strong, straight, and conical. Fang short and small. 



Maxilla rather long and strong, especially at the base ; slightly 

 enlarged at the extremities, inclined towards the labium, and slightly 

 impressed transversely about the middle. 



Labium somewhat oblong, and rather narrower at the apex than 

 at the base. 



Legs not very long or strong, nor very different in their relative 

 length, which is 4, 1, 2, 3 ; terminal tarsal claws three. 



Abdomen oval, moderately convex above ; united to cephalothorax 

 by a short but distinct cylindrical pedicle ; spinners six, those of 

 the inferior pair largest, two-jointed, and slightly curving upwards 

 over the abdomen. 



This genus, which, after some hesitation, I have formed for the 

 reception of several species of minute and curious Spiders, appears 

 to connect the genera Lachesis and Euyo. The position of the eyes 

 is decidedly different from both, while the general form and struc- 

 ture is very like the former. 



Pal^stina dentifera, sp. nov. 



Male adult, length 1| line. 



The cephalothorax, falces, legs, maxillae, labium, and sternum 

 of this species are of a bright orange yellow-red, the legs being 

 rather the lightest-coloured. The surface of the cephalothorax is 

 roughened by small punctures, and is very sparingly furnished with 

 hairs. The clypeus is prominent, and its margin rounded and pro- 

 jecting over the base of the falces ; its height equals the length of 

 the line formed by the foremost row of eyes ; these are in two 

 slightly curved and almost concentric rows (the hinder row less 

 curved than the front one) near to each other ; the centrals of the 

 hinder row are further from each other than each is from the lateral 

 on its side, and are the smallest of the eight, while the two fore 

 centrals are distinctly the largest ; and all except these are pearly 

 white ; the interval between the eyes of each lateral pair is equal 

 to the diameter of the fore one. The legs are rather slender, and
