var tilstede som et Rudiment, er her meget stærkt 

 udviklet, fuldkommen saa laug som deu 4de, og ud- 

 præget kloformig. Deu er i Yderkauten besat med 

 iine B(n'ster og har Inderkauteu fiut og regelraæssigt 

 sagtakket. Coxallajipeu er uoiagtig af samme Ud- 

 seende som paa Iste Par. Deriuiod er de 2 ydre 

 Vedhæng, og uavulig Exopoditeu (ex) forholdsvis 

 storre. 



De folgeude 7 Par gaar suecessivt over til at 

 autage det Udseeude, som lOde Fodpar viser. Dette 

 sidste (Fig. 16) er idethele kortere og mere sammeu- 

 trængt, udeu uogen tydelig Segmentering eller knæ- 

 formig Boiuing af Stammen. (Joxallappen er for- ' 

 lioldsvis noget mindre eud paa de 2 forreste Par og 

 mere lige indadrettet. Euditerue er kortere og bre- 

 dere, næsteu pladeformige, og deu yderste bredt 

 laneetformig samt tæt borstebesat i den ydre Kant. 

 De ydre Vedhæng er begge af anselig Storrelse, og 

 navnlig Exopoditeu (ex) betydelig storre end paa de ; 

 forreste Par: dens Form er ogsaa uoget forskjellig, ■ 

 idet den er mere oval, med den nedre Flig bredt ' 

 afruudet. 



Ute Fodpar (Fig. 17") viser et fra de øvrige 1 

 Fodder meget afvigende Udseeude, idet de 2 ydre 

 Vedhæng her er omdannede paa en eiendommelig 

 Maade, saa at de tilsammeu danner en æskeformig 

 Kapsel, hvori Æggeue midlertidigt optages, for at 

 forsynes med sin Skal. Laaget af Kapselen, der 

 vender fortil og er af regelmæssig circulær Form, 

 daunes af Epipoditen, medens Bunden af Kapselen i 

 ndgjores af Exopoditeu. (Jgsaa denne er af tilruu- 

 det Form, men uoget bredere end Epipoditen, og 

 udspi'inger med en bred Basis fra Stammen. Begge 

 slutter temmelig noie sammen, dog saalede.s, at der 

 paa deu ydre Side er eu reudeformig Fordybniug, 

 der dannes af de omboiede Kanter af Exopoditeu. 

 Selve Stamraeu er kort og bred, pladeformig, og deu 

 yderste Endit ikke tydeligt begrændset, dannende 

 en umiddelbar Fortsættelse af Stammen i Form af 

 en triangular Lap. 



L2te Fodpar (Fig. 18) viser igjen et mere uor- 

 malt Ldseende og stemmer idethele i sin Bygning 

 uoie overens med 10de 1'ar, uaar undtages, at det 

 er mindre og Jiar deu yderste Endit forholdsvis kor- 

 tere og bredere. Det samme er ogsaa Tilfældet med 

 Exopoditeu, hvis nedre Del er mindre fremsprin- 

 geude. 



De folgeude Fodpar aftager siiccessivt i Stor- 

 relse og bliver tilsidst ganske rudimentære, skjondt 

 alle de Dele, dei' tindes paa de foregaaeude Par, 

 lader sig paavise.

 Par ved samme Forstørrelse som de foregaaeude 

 Par. Det vil sees, at Euditerue er betydeligt redu- 



The outermost, or Tith endite, which iu the tirst 

 pair was only found as a rudiment, is here very 

 strongly develo])ed, is fully as long as the 4th, and 

 of a pronounced claw-like shape. The outer edge 

 is clothed with fine bristles, and the inner edge 

 finely anil regularly serrated. The coxal lobe is of 

 exactly the same appearance as in the first pair. 

 The two outer appendages, on the other haud. 

 and especially the exopodite (ex), are comparatively 

 larger. 



Through the 7 succeeding pairs there is a 

 gradual transition to the appearance of the lOtli 

 pair of legs. This pair (fig. IG) is on the wliole 

 shorter and more compact, witliout any distinct seg- 

 mentation or geniculation of the stem. The coxal 

 lobe is relatively rather smaller than that in the 

 foremost 2 pairs, and its direction is more directly 

 iuwards. The eudites are shorter and broader, al- 

 most lamellar, the outermost l.ieing liroadly lanceolate 

 iu form, and densely setous on the distal edge. The 

 outer appendages are both of considerable size, the 

 exopodite (ex) especially being much larger than in 

 the foremost pairs. Its shape is also somewhat dif- 

 ferent, being more oval, and the lower lobe more 

 broadly rounded. 



The 11th pair of legs (fig. 17) exhibits a ver^^ 

 dilFerent appearance from the others, the 2 outer 

 appendages being transformed iu a peculiar manner, 

 so as together to form a box-like capsule in which 

 the ova are temporarily recei\'ed in (U'der to be fur- 

 nished with their shell. The lid of the capsule, 

 which turns to the front, and is of a regularlj^ cir- 

 cular .shape, is formed by the epipodite, while the 

 bottom of the capsule consists of the exopodite. 

 This, too, is of a rounded form, but rather lu'oader 

 thau the epipodite, aud issues with a broad base 

 from the stem. The two parts fit together tolerably 

 exactly, yet in such a manner that on the outer 

 side there is a channel-like hollow formed by the 

 deourved edges of the exopodite. The stem itself is 

 short, broad and lamellar: the outermost endite is 

 not clearly defined, and forms a direct continuation 

 of the stem iu the shape of a triangular lobe. 



The 12th pair of legs (fig. 18) exhibits a more 

 normal a])pearauce, and, on the whole, agrees very 

 nearly iu its structure with the lOth pair, excepting 

 that it is smaller, and that the outermost endite is 

 relatively shorter and broader. This is also the 

 case with the exopodite, tlie lower part of which is 

 less projecting. 



The succeeding pairs of legs decrease succes- 

 sively iu size, and at last become ([uite rudimen- 

 tary, although it is possible to distinguish all the 

 parts that are found iu the preceding pairs. 



Fig. 19 reju-esents a leg of one of the hindmost 

 pairs magnified with tlie same power as the pre- 

 ceding pairs. It will be seen that the eudites are
