186 ARACHNIDES. 



Episinus, Walck. 



Eight eyes also, but they are approximated on a common eleva- 

 tion; the thorax is narrow and almost cylindrical l). 



In the remaining Inequitelae, the first pair of legs, and then the 

 second, are the longest. Such is the 



Pholcus, Walck. 



Where the eight eyes are placed on a tubercle, and divided into 

 three groups; one on each side consisting of three eyes, forming a 

 triangle, and the third in the middle, somewhat anteriorly, and com- 

 posed of two on a transverse line. 



Ph. phalangioides, Walck., Hist, des Aran., fasc. V, tab. x; 

 draignee domestique a longues pattes, Geoff. The body long, 

 narrow, pale yellowish or livid, and pubescent; abdomen nearly 

 cylindrical, very soft, and marked above with blackish spots; 

 very long, slender legs; a whitish ring round the extremity of 

 the thighs and tibiae. Common in houses, where it spins a web 

 of a loose texture, in the angles of the walls. The female cements 

 her eggs into a round naked mass, which she carries between 

 her mandibles. 



M. Dufour has found a second species, the Pholque a queue 



Ann. des Sc. Phys. V, lxxvi, 2, in the clefts of the rocks in 



Moxente, Valencia. Its abdomen terminates in a conical point, 



and thus forms a sort of tail, like that of the Epeira conica. 



Like the preceding species, it balances its body and feet. The 



genital organs of the male are very complex. 



In the third section of the sedentary rectigrade spiders, the Or- 



bit:el;, or Jiraignees Tendeuses of others, the external fusi are 



almost conical, slightly salient, convergent, and form a rosette; the 



legs are slender, as in the preceding section, but the jaws are straight 



and evidently wider at their extremity. 



The first pair of legs, and then the second, are always the longest. 

 There are eight eyes thus arranged: four in the middle forming a 

 quadrilateral, and two on each side. 



The Orbitelae approach the Inequitelae in the size, softness, and 

 diversity of colour of the abdomen, and in their short term of exist- 

 ence; but their web is a regular piece of net-work, composed of con- 

 centric circles intercepted by straight radii diverging from the cen- 

 tre, where they almost always remain, and in an inverted position, at 

 the circumference. Some conceal themselves in a cell or cavity
