noget skjævt opadrettet og mangler enhver Art af Bevæb- 

 ning. 



Øieknuden (Fig. 1 c) har sin Plads betydelig foran 

 Midten af Hovedsegmentets E&ygside, ikke langt fra For- 

 kanten. I >en er af noget aregelmæssig stump konisk Form 

 og har de 4 Corneæ beliggende nær Basis. Ved nøiere 

 Dndersøgelse viser disse sidste sig af noget nlige Størrelse, 

 idet de 2 forreste er kjendelig større end de 2 bagerste. 



Snabelen udgaar (se Fig. 1 a) noget ventralt fra Ho- 

 vedsegmentets Forende og er lidt skjævt nedadrettet. Den 

 er neppe halvt saa lang som del øvrige Legeme og af 

 cylindrisk Form, med Enden stumpt afkuttet; ganske nær 

 Spidsen har den en svag cirkulær [ndknibning (se Fig. 1 b). 

 Mundaabningen er af den sædvanlige triangulære Form. 



Saxlemmerne (Fig. 1 d) er forholdsvis kraftigt udvik- 

 lede og betydelig hengere end Snabelen. De bestaar af et 

 temmelig tykt, lige fortil rettet, cylindriskt eller noget 

 kølleformigt, enleddet Skaft, og et med dette meget bevæ- 

 geligt forbundet terminalt Afsnit, Saxen. Denne sidste er 

 af oval Form. kortere end Skaftet og ligesom dette ganske 

 glat. Fingrene er særdeles kraftige og stærkt chitiniserede, 

 omtrent af Palmens Længde og mod Enden meget stærkt 

 hageformigt krummede, saa at der mellem dem altid er et 

 meget stort aabent Kum. Den bevægelige Finger, som lig- 

 ger nederst, er noget hengere end den ubevægelige, saa at 

 den. naar Saxen lukkes, hegger sig med Spidsen udenom 

 den ubevægelige, uden at krydse samme (se Fig. 1 e). 



Af Følere er der. ligesaalidt som hos de i det fore- 

 gaaende beskrevne Former, det mindste Spor at opdage. 



De falske Fødder i Fig. 1 f), som kun er tilstede lios 

 Hannerne. er indleddede paa hver Side til et Helet knude- 

 formigt Fremspring, der ligger noget ventralt umiddelbart 

 foran lnsertionen af de forreste Sidefortsatser (se Fig. 1 a, 

 1 b). De er forholdsvis kraftigt udviklede og. lige udstrakte, 

 næsten af Kroppens Længde. naar Snabelen finregnes. 

 Ialmindelighed viser de imidlertid en meget stærk S-formig 

 Bøining og er slaaede ind under Dyrets Bugside. De be- 

 staar kun af .") tydeligt begrændsede Led. og naar Krøyer 

 har beskrevet disse Lemmer som 7-leddede, da kommer 

 dette aabenbart deraf, at han har regnet det knudeformige 

 Fremspring, hvortil de er tæstede. som et særskilt Led og 

 desuden feilagtigt har tåget en sVag Indknibning i Midten 

 af sidste Led som en virkelig Artikulation. Af Leddene 

 er det Iste kortest men temmelig tykt. det 3die længst og 

 2det og 4de omtrent af ens Størrelse. Sidste Led er lidt 

 kortere end disse, dog forholdsvis bredere, sammentrykt og 

 stærkt krummet, uden Klo, men bevæbnet i [nderkanten 

 nær Basis med 3 tæt sammentrængte hageformige Torner 

 og desforuden til hver Side meil en Rad af lignende skjøndt 

 noget svagere Torner. Forøvrigt er disse Lemmer kun 

 meget sparsomt besatte med meget smaa, simple tornformige 

 Børster. 



oval torm. and not distinctlj marked off from the last seg- 

 ment of the trunk; it is always directed somewhat obliquely 

 upward, and does not exhibit any kind of armature whatever. 



The oculiferous tubercle (fig. 1 c) has its place con- 

 siderably anterior to the middle oi the dorsal surface of 

 the cephalic segment, not far from the anterior margin. 

 It exhibits a somewhat irregular obtusely-conic form, and 

 has the 1 corneæ placed near the base. On (doser exam- 

 ination these are found to differ somewhat in size, the 2 

 foremost being appreciably larger than the 2 hindmost. 



The proboscis issues (see fig. 1 a) a Little ventrally 

 from the anterior extremity of the cephalic segment, and 

 points somewhat obliquely downward. It is nardly half 

 as long as the rest of the body and of cylindric form. with 

 the extremity obtusely truncate; in close proximity to the 

 point it has a faint circular constriction (see fig. 1 bi. The 

 buccal orifice is of the usual triangular form. 



The chelifori (fig. 1 d) are of comparatively powerful 

 development and considerably longer than the proboscis. 

 Thev consist of a rather thick, anteriorly directed, cylin- 

 dric or somewhat claviform. one-jointed scape and. con- 

 nected very movably with it. a. terminal section, the chela. 

 The latter is oval in form, shorter than the scape. and. 

 like that part, quite smooth. The fingers are exceedingly 

 powerful and highly chitinized, about as long as the palm, 

 aud towards the extremity very strongly hooked, so as always 

 to admit of a large open space between them. The mov- 

 able tinger being the Iower of the two, is a trifle longer 

 than the immovable, and hence. on the chela being shut, 

 it will lie with the point beyond the immovable one, without 

 crossing it (see tig. 1 e). 



Of palpi. as in the forms previously described, not 

 the slightest trace can be found. 



The false legs (fig. 1 f), present in the males only, 

 are jointed on either side to a small tubérculiform pro- 

 jection, lying in a somewhat ventral position immediately 

 anterior to the origin of the foremost lateral processes (see 

 fig. 1 a. 1 b). Thev are comparatively of powerful devel- 

 opment, a ml. when fully extended, well-nigh equal in length 

 to the body, excluding the proboscis. Generally, however, 

 1 1 1 1 • \ assume a very decided sigmoid curve, and are folded 

 in under the ventral surface of the animal. They consist 

 of 5 distinctly defined joints, and if Krøyer has described 

 these limbs as seven-jointed, this must obviously arise from 

 his having counted the tubérculiform projection to which 

 they are affixed as a distinct joint, and moreover errone- 

 ously having mistaken a faint constriction in the middle 

 of the last joint for a true articulation. Of the joints, 

 the Ist is shortesf, but rather thick. the 3rd longest aud 

 the 2nd and 4th about equal in size. The terminal joint is 

 a Little shorter than the two last. but relatively broader, 

 compressed, and strongly curved, without any claw, though 

 armed along the inner margin with 3 closely set, ungui- 

 form spines. and having besides on either side a row of 

 similar but somewhat feebler spines. For the rest. these 

 limbs are very sparingly beset with exceedingly small, 

 simple spiniform bristles.
