rende til hvad Tilfældet er paa de egentlige Fødder. Samt- 

 lige Led er mere eller mindre tæt børstebesatte. Navnlig 

 er det yderste Afsnit tæt baaret og i Kanterne med visse 

 Mellemrum desuden bevæbnet med Knipper af tynde Torner. 



Iste Fodpar (Kig. 16) er neppe længere end 3die Par 

 Kjævefødder, men langt kraftigere bygget. Det er som de 

 følgende Par enkelt, nden ydre Vedbæng ved Basis, og 

 bestaar, den bevægelige Finger iberegnet af 7 vel begrænd- 

 sede Led. hvoraf de 3 første er ganske korte. 4de Led 

 forbinder sig med det foregaaende ved en meget skjæv Arti- 

 culation og er noget udvidet mod Enden samt af kantet, 

 næsten prismatisk Form; den ydre Kant løber fortil ud i 

 en temmelig st;erk tornformig Fortsats og er omkring denne 

 besat med lange Børster. 5te Led er ganske kort. neppe 

 Lengere end bredt og meget bevægeligt forbundet saavel 

 med det foregaaende som efterfølgende ; det er paa den 

 ydre Side tæt baaret og gaar oventil ved Enden ud i 2 

 stærke Torner. 6te Led eller Haanden er kraftigt udviklet, 

 ved Basis ligesom opsvulmet, fortil mere og mere afiiadet 

 og ogsaa noget bredere. Enden er næsten tvært afskaaret 

 og danner en skarp, noget buet Kant, iniod hvilken den til 

 det ydre Hjørne fæstede kloformige Finger kan indbøies. 

 Det indre Hjørne er udtrukket til en skarp lige fortilrettet 

 Fortsats, der forestiller den rudimentære ubevægelige Finger. 

 Haanden er ligesom Størsteparten af den øvrige Fod kun 

 besat med meget korte Haar, 



2det Fodpar (Fig. 17) er meget tyndt og svagt bygget. 

 men lige udstrakt neppe kortere end Iste. Det bæres ial- 

 mindeligbed slaaet ind under Forkroppen og er derfor 

 sjelden synligt, naar Dyret sees ovenfra. Af Leddene er 

 4de og 5te Lengst og danner med hinanden en mere eller 

 mindre stærk knæformig Bøining. 6te Led eller Haanden 

 er' neppe bredere end det foregaaende og omtrent halvt saa 

 langt. Spidsen danner en liden, men fuldstændig Sax (se 

 Fig. 18), paa hvilken dog Fingrene er særdeles korte, idet 

 de neppe er ';,; saa lange som Palmen. 



3die Fodpar (Fig. 19) er ubetydelig Lengere end lore- 

 gaaeude. men noget kraftigere bygget, navnlig hvad det 

 basale Afsnit angaar. Det afsmalnes successivt mod Enden, 

 der er sylformigt tilspidset. Af Leddene er det 5te Lengst. 

 Det overmaade lille sidste Led eller Endekloen gaar i Flugt 

 med næstsidste, men er skilt fra samme ved en tydelig 

 Sutur. 



De 2 følgende Par (Fig. 20), der forestiller de egent- 

 lige Grangfødder, er indbyrdes af ens Udseende. omtrent af 

 foregaaende Pars Længde, men langt kraftigere byggede. 

 Af Leddene er 4de og 6te Lengst og omtrent indbyrdes 

 lige lange og betydelig storre end 5te. Sidste Led er orn- 



at the point of the last segmenl eau be detected an extremely 

 minute. thougb distinctly defined terminal articulation. Hence, 

 the number of articulations is strictly 7. corresponding to 

 tliat on the true leLis. All the articulations are more or 

 liss closely beset witb bristles. The outermost section, 

 in particular. is densely clothed witb hairs. and at inter- 

 vals furnished along the edges witb bunches of slender spines. 



The Ist pair of legs i tig. 16) are scarcely at all 

 Longer than the 3rd pair of maxillipeds. Like the follow- 

 ing pairs, tbey are simple, having no exterior appendages 

 at the base, and eonsist. inclusive ol the moveable dactylus, 

 of 7 distinctlj separated segments, of which the 3 hrst 

 are exceedingly sbort. The 4tli segment is connected witb 

 the preceding by means of an extremely oblique articula- 

 tion. and is somewhat expanded towards the extremity, 

 witb an angular. almost prismatic form: the outer margin 

 extends forward (anteriorly) as a rather prominenl spini- 

 form projection, beset round the latter with long bristles. 

 The 5tb segment is quite sbort, scarcely longer than broad, 

 and very tiexibly connected alike with the preceding and 

 the succeeding segments; on the outer side. it is densely 

 clothed with hair, aud projects at the extremity, above, into 

 2 powerful spines. The 6th segment, or hand, is strongly 

 developed, with the base, as it were, swollen, anteriorly 

 gradually applanated, and also somewhat broader. The ex- 

 tremity is well-nigh truncate, and constitutes a sharp, slightly 

 arcuate edge, towards which the unguifbrm dactylus. at- 

 tached to the outer corner, admits of bending in. Theinner 

 corner is drawn out into a sharp tooth, directed straight 

 forwards, which represents the rudimentary immobile tinger. 

 The hand. like the greater part of the rest of the foot, is 

 clothed with exceedingly short hairs. 



The 2nd pair of legs (tig. 17) are very thin and of 

 fragile construction. hut. fully extended. hardly shorter than 

 the Ist pair. As a rule, tbey are carried, doubled up under 

 the cephalo-thorax. and hence are rarely visible when the 

 animal is seen from above. Of the segments, the 4th aud 

 5th are the longest, and constitute together a more or 

 less prominent geniculate rlexure. The 6th segment, or 

 hand. is scarcely at all broader than the preceding. and 

 about half as long. Its extremity assumes the shape of 

 a small, but perfectly formed chela isee fig. 18). on which. 

 however the dactyli are exceedingly short. attaining scarcely 

 one-third the length of the palm. 



Ihe ord pair of legs (fig. 19) are but very little 

 longer than the preceding, of a somewhat more powerful 

 structure, however. in particular the basal section. Tbey 

 taper graduaUy to the extremity. which has an awl-shaped 

 point. Of the segments, the 5th is the longest. The last. 

 exceedingly small segment, or terminal claw, projects in a 

 line with the penultimate. from which, however. it is sepa- 

 rated by a well-marked suture. 



The 2 succeeding pairs (tig. 20), which represent the 

 true ambulatory feet, are similar in appearance, of about 

 the same length as the preceding pair, but much more 

 powerful in structure. Of the segments, the 4th and 6th 

 are the longest, about equal in length, and considerably
