'^^O AT^.^i^CllNIDA. 



The second section of the sedentary and rcctigrjide Spiders— lliat of ilic IxKauiTEL.r; or S})i)ir.in'T 

 S])idcrs [Araiijupcs fllaiulicres), has t'lc external spinnerets nearly conical, yery slightly exsertcd, 

 eonvcrgenl-, arraiiy:ed in a roselte, and the lei^s very slender. The ma\ilhe iiieiine towards tlie tongnc, 

 and are naiTow at the tii), or at lea^.t arc not dilated. Tlie majority have the fw.^t i>\d\- of legs, and 

 then tlie fonrth, llie longest; the aluhniien is larger, softer, aiul more colonied than in the preceding 

 tribes. They construct wehs with irrj-egular meslies composed of llireads, v>hieh cross in aU diii.'ctions 

 and different surfaces. They whirl threads round their prey, take great pains in the ijreservution of 

 their eggs, and do not leave them until they are hatched. They live but a short time. 



Sci/fo(-h'\\ Latr., lias only six eyes, arranged in pairs, and the nn;;ues of tlie tarsi are inserted upon a supple- 

 mental joint, .b'. tlioracica, Latr., inhabits the interior of our apartments; anotlier species, -S'. ntbe.sccn.^-, was 

 found by Dufour in the niountaius of Valencia. It fubricates an irrejjTiIar tube of slender texture, of a milky- 

 white, like that oi D//sdcra en/fhrlno. 



Thcriilion, AValck., has ei.i^ht eyes thus arran^-ed, four in the miildle in a square, ihe two anterior ones placed nn 

 a protuberance, and two on each side, also placed on an elevation common to both ; the thorax is like a reversed 

 heart, or nearly trianp^ular. The species are very mmierous. Ty^e, Aranea IS-rfuftala, Fabr., Rossi.— Found 

 in Tuscany and the island of Corsica. Its bite is considered very venomous, and even mortal.*— (See the TnLlcaic 

 and the UUioire dcs Araneides of Walckenaer ; the Annales de--; -S'a. N'ainr., and the Aiui. da- Sci. Physlq.) 



A. riiaclnns, Fab., an American species, is similarly dreaded. These fears seem more to originate iu the bl.aek 

 colour of the animal.v, wliiib are marked with blood-coloured spots. T. l«-,i.iuinini,y\ -.ilck., takes up its abode lit 

 bunches of g-rapes, and thn.^ ilefends them from the attacks of other inserts. 



£/?/W//if.?, \Vaick,,— has also eight eyes, but which are placed close to^'-ether upon a common elevation of the 

 narrow and subcylindric thorax. E. truncatiis, Latr. Paris, Italy. 



PholcHS, Walck.,— has the tirst and then the second legs the longest; the eyes, ei;^ht in numljer, are placed npon 

 a tubercle, ami arran^^ed in tliree groups, one on each side composed of three eyes placed in a trian.^-le, and the t\\ o 

 others in tlie midille, in a transvi-rse row. Ph. Phalaiigiokh's^ ^Yalck., has the body lon^ and very narrnw, of a 

 A'ery ]iale li\ id colour ; aljdoim.'u \ cry soft, and marked above with blackish spots; Iej;-s extremely lon^- and \XTy 

 slender, with a wliiti' riiiL,^ at the tip of the thighs and tibiK. It is common in houses, wdiere it spins a "v^elj 

 composed of loose thi-eads in the angles of walls. The female gums her eggs into a rounded naked body, whicli it 

 bears about iu its jaws. Dufour found another species in the crevices of rocks in Valencia. Like the preceding, 

 it balances itself backwards and forwards upon its very slender feet. 



The third section of the sedentary rectigradc Spiders is that of the Orritel-e, or Ihc Araifjnf-cs 

 tendeuses of some authors, having the external S]iinncrets nearly conical, slightly exsertcd, convergent 

 and arranged in a rosette, the legs slender, and the maxilla:' straight or sensibly widened at the tip; 

 t!ie tirit pair of legs, and then the second, arc ahvays the longest. The eyes are eight in nuniher, and 

 thus arr;ingcd, — four in the middle in a square ami the two others on each side. They resemble tlie lue- 

 fjuitcln; in the size, softness, varie'il I'olours eif tin; ahdnnien, and shnrtncss of ihear lives ; hut thc^■make 

 their \\clis with regular meshes, arranged in concentric circles crossed by straight radii extemhng from 

 the circumference and meeting in the centre, where the insects remain stationary and iu a reversed 

 positiun. Some species secrete themselves in a cavity or cell whieh they construct near the edges of 

 tlie net, which is sometimes horizontal and sometimes jierpemiiciLiar. The eggs arc agglutinated 

 together, vei'v numerous, and incln^ed in a large coeonu. 'I'he threads whicli sup[)0rt tlic weli, and 

 whicli stretch to about a fifth iheir length, are used for the divisiuiis of the micrometer, an astruuumical 

 instrument, as we learn from M. Arago. 



Z.i']»_v/^/;/Vt, Latr., has four of the eyes in the middle, forming a trapezium widest behind; ihe two hinder eyes 

 being larger than the rest, and the four others, arranged in two pairs, one on each side aiel m an oblique direction. 

 The maxilla: are dilated at the tip. L. trkuif/iilarls, AValck. ; Araiwa moniana^ Linn,, 6cc. They construct upon 

 various shrubs an horizontal slender web, attached by irregular threads in many points ; this web is thus a 

 melange of those of the I/icrjid(c/cC and Orhitcla;. The insect stations itself on the under side in a transverse 

 position. 



U/o/'uni.'i, Latr., has the fmir posterior eyes placed at cjual distances in a straight line, ami the two latei-al ones 

 of the ftont line nearer the front edgenf the liioiax tlian the two intermediate ones. The maxiI]a_M\ideu from 

 near the base, and are spatulated at the iqi ; tin' taisi of the three hind pairs of legs are terminated by a single 

 unguis. Tlie body is long and subcylinilrical. When statinned in the middle of their web, tliey stretch their four 

 fore-legs forward in a straight line, and their two hind ones in an opposite direction, the third pair being laterally 

 extended. They make webs like the other OrbitelK, but looser and horizontally. The cocoon is narrow, long, 

 angular at the sides, and suspended vertically by one end to a net; the other end is produced into two points, as 

 stated to me l»y i\I. Uufour. U. ^Valc/:cllae^■^us, Lat. ; found in the woods of the environs of Uordeaux, and other 

 soutliei'ii de|)artinents ; five lines lung. 



* 'I'liis .'iK'cius is tlip type ol' Wiilckeiiiier's ijuliuis LiitroUectes, fuundtid upon supyoscil diffcrencu.s in tlic rcklivc Iciii^tli of llie leg's.
