not very unequal in size, and margined with black ; they are in two 

 transverse rows, the hinder one of which is curved away from the 

 front row ; the eyes of this last (which is a little the shortest) are 

 equidistant from each other, as are also those of the hinder row ; 

 those of each lateral pair are near to each other, but not quite con- 

 tiguous. The legs are long and rather slender (their relative length 

 1, 4, 2, 3), and they are furnished with hairs and a very few spines ; 

 these last are chiefly on the legs of the third and fourth pairs. The 

 palpi are rather long and slender. The maxillce and labium are of 

 a light yellow-brown colour. The abdomen is oval, and projects con- 

 siderably over the base of the cephalothorax ; it is of a dull yellow- 

 brown colour, clothed with yellow-grey hairs, and mottled thickly 

 with clearer yellow cretaceous-looking spots ; these are brightest and 

 most conspicuous in the immediate vicinity of the normal elongate 

 longitudinal marking on the fore half of the upperside, this mark- 

 ing, of a dark dull brown colour and well defined, having a bold sub- 

 angular prominent point at its middle on either side, and a smaller 

 one between that and its fore extremity ; its hinder extremity ends 

 in a point. On the underside the cretaceous spots are thick and 

 conspicuous. Probably in life the abdomen was of a greenish hue ; 

 but of this I have no certain recollection. 



In two other examples, which Dr. Koch considers to be of the 

 same species, the abdomen was of a clearer bright yellow (in the 

 cabinet specimens), and, except a few near the normal elongate 

 marking on the fore part of the upperside, there were no cretaceous 

 spots either above or below ; and this normal marking was paler and 

 less well defined. Perhaps the cretaceous spots are dependent on 

 age and the consequent cracking as it were of the epidermis after 

 the deposition of ova.

Adults of both sexes of this fine and handsome Spider, which is 

 allied to C. rnttrix, but very distinct, were found on low-growing 

 plants at Jerusalem. 



Genus Trachelas (L. Koch). 

 Trachelas minor, sp. nov. (Plate XVI. fig. 41.) 



Female adult, length not quite 1^ line. 



Cephalothorax oval, with the profile-line of the caput and thorax 

 level ; but the caput is well defined by the ordinary oblique lateral 

 indentation ; it is of a bright yellowish-red colour, very sparingly 

 clothed with hairs ; the whole is thickly covered with minute im- 

 pressed dots or punctures ; and the hind slope is rather abrupt. The 

 eyes are rather large, but not very different in their relative size ; 

 they are in two very nearly concentrically curved transverse rows (the 

 fore one of which is the shortest), and close to each other, but not 

 contiguous ; the interval between those of the fore central pair is 

 greater than that between each and the fore lateral on its side, with
