A subgenus established by M. Walckenaer, under tlie name of Sto- 

 RENA, but which is yet but imperfectly known, should apparently 

 terminate this section and lead to Oxyopes, which are as nearly allied 

 to the Crab-Spiders as to the Citigradre. The Storenae have their 

 jaws inclined on the ligula, which is nearly of the same length, and 

 forms an elongated triangle ; the chelicerae are conical ; the two ante- 

 rior legs, and then the second, longest; the two following ones longer 

 than the last. The eyes are arranged in three transverse lines, 2, 4, 

 2; the posterior, with the two intermediate ones of the second lines, 

 form a small square, and the two anterior ones are distant f. 



Other Araneae whose eyes, always eight in number, extend more 

 along the length of the thorax, than across its breadth, or at least 

 almost as much in one direction as the other, and which form either 

 a truncated curvilinear triangle or oval, or a quadrilateral, constitute 

 a second general division, or the VagabundjE, which I have thus 

 named to distinguish them from those of the first, or the Sedentariae. 



Two or four of their eyes are frequently much larger than the 

 others ; the thorax is large, and the legs robust ; those of the fourth 

 pair and then the two first, or those of the second pair, are usually 

 the longest. 



They make no web, but watch for their prey and seize it, either by 

 hunting it down, or by suddenly leaping upon it. 



We divide them into two sections. 



The first, that of the Citigrad^e, is composed of the Araignees- 

 Loups of authors. The eyes form either a curvilinear triangle, an 

 oval, or a quadrilateral, of which, however, the anterior side is much 

 narrower than the widest part of the thorax. This j^art of the body 

 is ovoid, narrowed before, and carinated along the middle of its length. 

 The legs are usually only fit for running. The jaws are always 

 straight, and rounded at the end. 



Most of the females remain on their cocoon, or carry it with them 

 at the base of the abdomen, or suspended to the anus. Nothing but 

 the most extreme necessity will induce them to abandon it, and, when 

 the danger is over, they always return in search of it. They also 

 take care of their young for a certain period after they are hatched. 



Oxyopes, Lat. — Sphasus, Walck. 



The eyes arranged two by two, or four transverse lines, the two 

 extreme ones the shortest; they describe a sort of oval, truncated at 

 each end. The ligula is elongated, narrowest at base, dilated and 

 rounded towards the end. The first pair of legs is the longest ; the 

 fourth and second are nearly equal; the third is the shortest J.
