PULMONARUE. 297 



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

 Araign^e domestique a loiigues 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 

 t lie "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, Ixxvi, 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 Epcira 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 ORBI- 



K, or Araiynees 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 ; hut their web is a regular piece of net-work, composed of con- 

 centric circles, intercepted by straight radii diverging from the 

 centre, where they almost always remain, and in an inverted position, 

 at the circumference. Some conceal themselves in a cell or cavity 

 which they have constructed near the margin of the web, which is 

 sometimes horizontal, and at others perpendicular. Their eggs are 

 agglutinated, very numerous, and inclosed in a voluminous cocoon. 



The threads which support tho web, and which can be extended 

 one-fifth of their length, are used for the division of the micrometer. 

 This observation was communicated to us by M. Arrago. 



LINYPHIA, Lat. 



The Linyphi;e are well characterized by the disposition of their 

 eyes; four in the middle form a trapezium, the posterior side of 

 which is widest, and is occupied by two eyes much larger and more 

 distant ; the remaining four are grouped in pairs, one on each side, 

 and in an oblique line. The jaws are only widened at their superior 

 extremity. 



They construct on bushes a loose, thin, horizontal web. attaching 

 to its upper surface, at different points, or irregularly, separate 

 threads. The animal remains at its inferior portion, and in a reversed 

 position*.
