A subgenus established by M. Walckenaer, under the name of Sto- 
RENA, but which is yet but imperfectly known, should apparently 
terminate this section and lead to Oxyopes, which aie as nearly allied 
to the Crab-Spiders as to the Citigrad?e. The Storenee 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 Vagabund.e, which I have thus 
named to distinguish them from those of the first, or the Sedentarise. 
Two or four of their eyes are frequently mucli 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 Citigradas, 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 part 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.
