Øieknuden ise Fig. 1 a, 1 c) er særdeles lav, jevnt af- 

 rundel og beliggende ved den bagre Trediedel at' Hoved- 

 segmentets Længde, eller lige over Basis at' Halsen. De 4 

 Lindser or (se Fig. 1 e) forholdsvis smaa og temmelig 

 vidt adskilte; til enhver af dem hører en skarpt begrændset 

 btegerformig Ansamling af mørkt Pigment, hvis Spids ven- 

 der mod Centrum af Øieknuden. 



Snabelen er (se Fig. 1 a, 1 b, 1 c) betydelig kortere 

 end Hovedsegmentet, horizontah fortilrettet og af konisk 

 Fonn. Spidsen er (se fig. 1 d) uddraget til en kort Mam- 

 mille, hvorpaa Mundaabningen er beliggende. Den er ikke 

 som hos loregaaende Slægt, omgivet at' nogen egentlig Børste- 

 krands, men kun, ligesom det tilgrændsende Parti af Sna- 

 belen, tint eilieret. 



Saxleinmerne (se Fig. 1 a, 1 b, 1 c), der er fæstede til 

 Pandedelens Sidehjørner, adskilte ved et temmelig betydeligt 

 Mellemrum, er overordentlig kraftigt udviklede og ai næsten 

 kølledannet Form. Skattet er forholdsvis tykt. cylindriskt 

 og, naar undtages nogle meget smaa Haar ved det ydre 

 Hjørne, ganske glat. Haanden (Fig. 1 11 er omtrent af Skaf- 

 tets Længde, men mere end dobbelt saa bred, næsten kugle- 

 formigt npsvulmet og tæt besat med fine Haar, der navnlig 

 henad den ubevægelige Finger bliver særdeles tætte og dan- 

 ner her et tykt tildtagtigt Overtræk. Den er horizontah 

 indadrettet, saaledes, at dens Ende ialmindelighed moder den 

 tilsvarende paa den anden Side lige under Spidsen af Sna- 

 belen (se Fig. 1 b). Fingrene er korte og tykke, paa langt 

 nær ikke af Palmens Længde, og sterkt chitinisere.de navn- 

 lig i Spidsen, som derved antager en mørk hornbrun Farve. 

 Den ubevægelige Finger, som i Haandens naturlige Stilling 

 ligger iottil. er ikke tydeligt afsat fra Palmen, hvis umid- 

 delbare Fortsættelse den danner. Den er forsynet indad 

 med en lamelleformig Fortsats, der er fint tandet i Kanten 

 og egentlig udgaar fra den nedre Flade, medens selve Kan- 

 ten at Fingeren viser sig indenfor den hageformigt krum- 

 mede Spids dybt indbugtet og længere bagtil forsynet med 

 et tandformigt Fremspring (se Fig. 1 f). Den bevægelige 

 Finger, der er betydelig smalere end den ubevægelige, har 

 paa Midten et lignende tandformigt Fremspring, der, naar 

 Saxen er lukket, griber ind mellem det tilsvarende Frem- 

 spring paa den ubevægelige Finger og den lamelletormige 

 Fortsats. 



Af Følere er der, ligesaalidt som hos de i det iore- 

 gaaende omtalte Pycnogonideer, det mindste'Spor at opdage 

 (se Fig. 1 b). 



De falske Fødder (se Fig. 1 b), der hver artikulerer 

 med et fra Siderne af Halsen tæt foran de forreste Sidefort- 

 satser udgaaende knudeformigt Fremspring, bestaar hos 

 begge Kjøn af 10 Led og ender meden vel ud viklet, skjøndt 

 ikke meget lang Klo Som sædvanlig er disse Lemmer hos 

 Hannerne sterkere udviklede end hos Hunnerne, og er hos 

 de første lige udstrakte, næsten D/2 Gang længere end Le- 

 gemet, hvad der væsentlig skyldes den betydeligere Stør- 

 relse af 5te Led. Medens dette Led hos Hunnerne (se Fig. 1) 

 neppe er hengen; end det foregaaende, er det her (se Fig. 

 1 b) fuldkommen lige saa langt som de 2 foregaaende til- 



The oculiferous tubercle (seefig. 1 a, 1 c) is exceedingly 

 low, evenly rounded, and placed on the posterior longitudinal 

 third-part of the cephalic segment, or immediately above the 

 base of the neck. The 4 lenses (se fig. 1 e) are compara- 

 tively small and rather far apart: to each of them belongs 

 a sharplv detined eup-shaped aggregatinn of dark pigment, 

 whose point is directed towards the centre of the oculiferous 

 tubercle. 



The proboscis (sec fig. 1 a, 1 b, I c) is considerably 

 shorter than the cephalic segment, of a conical tonn, and 

 directed horizontally forwards. The point (see fig. Id) is 

 drawn out to a short matnilla, on whieh occurs the oral 

 opening. It is not, as in the preceding genus, surrounded 

 by a definite wreath af sete, but like the adjacent part of 

 the proboscis is only rinely ciliated. 



The chelifori (see fig. 1 a. 1 b, 1 c), attached to the 

 lateral corners of the frontal part, and separated by a con- 

 siderable interval, are most powerfullv developed and well- 

 nigh claviform. The scape is relatively thick, cylindric, and, 

 saving a few very short hairs at the outer corner, perfectly 

 smooth. The hand ( fig. 1 f) measures about the length of 

 the scape, but is more than twice as broad, almost glo- 

 bularly tumified, and densely beset with tine hairs, which, 

 down the immobile finger especially, become exceedingly dense, 

 constituting here a thick, felt-like covering. It points hori- 

 zontally inwards. in such manner as generally to meet at 

 its end the corresponding one of the other side, immediately 

 under the tip of the proboscis (see fig. 1 b). The fingers 

 are short aud thick. not nearly attaining the length of the 

 palni. and are highly ehitinized, in particular at the point, 

 which thereby acquires a dark horny-brown colour. The 

 immobile finger, which in the natural position of the hand is 

 located anteriorly, is not distinctly detined trom the pabn. of 

 which it is a direct contiuuation. It is furnished inwards 

 with a lamelliform process, finely dentated on the edge and 

 really issuing from the lower surface, whereas the edge of 

 the finger itself appears, inside the unciform curvate point, 

 deeply emarginate and farther back provided with a denti- 



form projection (see Hg. 1 f). The mobile finger, a g 1 



ileal naiTower than the immobile, has in the middle a 

 similar dentiform projection. which, when the chela is 

 elnseil, interlocks with the corresponding projection on the 

 immobile finger and the lamelliform process. 



As in the Pycnogonidea previously mentioned, not a 

 trace of palpi can be detected (see fig. 1 ln. 



The false leg.- (see hg. 1 bi. each artieulating with a 

 nodular projection that issues from the sides of the neck 

 just in front of the foremost lateral processes, are in both 

 sexes composed of 10 joints, and terminate with a well de- 

 veloped although not very long claw. As usual, these limbs 

 are in the male more fully developed than in the female, 

 and attain in the lunner, when fully extended, well-nigh 

 one and a half times the length of the body, chiefly owing 

 to the nmch greater size of the 5th joint. While this 

 joint in the female 1 see Hg. 1) measures hardly as long as the 

 preceding one, it is here quite as long as the 2 loregoing
