med Dohrn at antage, at de 2 smaa ovenfor omtalte torn- 

 formige Fremspring paa den øvre Side af Eovedsegmentets 

 Pandedel repræsenterer et ubetydeligt Rudiment af de hos 

 Larverne tydeligt udviklede Saxlemmer, ligesom en buefor- 

 mig Chitinliste paa Siderne af dotte Segments Halsdel (se 

 Fig. 3 a) antyder det Sted, hvor hos Larverne de til Fo- 

 lerne svarende Lemmer har havt sin Plads. 



De falske Fodder (Fig. 3 f), der som hos foregaaende 

 Slægt kun er tilstede hos Hannerne (se Fig. 3c, od), er 

 forholdsvis betydelig kraftigere udviklede end hos denne 

 Slægt og lige udstrakte niere end halvt saa lange som hele 

 Legemet. Som hos andre Pycnogonideer er de fæstede paa 

 hver Side til et knudeformigt fra Hovedsegmentets Halsdel 

 udgaaende Fremspring, umiddelbart foran Legemets forreste 

 Sidefortsatser, og er hoiede ind under Kroppen, visende 

 en udpræget S-formig Krumning. De er kun sammensatte 

 af 7 Led. meget ulige i Længde og besatte med korte. 

 som oftest hageformigt ombøiede og uden nogen Orden for- 

 delte Torner. Hvad Leddenes indbyrdes Forhold angaar, 

 saa er det Iste forholdsvis kort og tykt, hvorimod 2det er 

 stærkt forlænget, mere end dobbelt saa. langt. De 2 føl- 

 gende Led er igjen adskilligt kortere og tilsammen neppe 

 betydelig længere end 2det, ote derimod niere forlænget, 

 skjondt kortere end 2det, og meget stærkt krummet. 6te 

 Led er af oval eller elliptisk Form og har ved Enden en 

 skaalformig Fordybning, fra hvis Bund det yderst lille 7de 

 eller sidste Led rager frem. Dette er af trekantet Form 

 Og uden Klo, men forsynet i den indre Kant med 2 korte 

 Torner af samme Beskaffenhed som de øvrige paa disse 

 Lemmer fæstede. 



Gangfødderne (se Fig. 3) er særdeles spinkle, næsten 

 3 Gange længere end Legemet, og besatte med spredte 

 Torner af noget ulige Størrelse. 2det Hofteled er temme- 

 lig stærkt forlænget, mere end dobbelt saa langt som dr 2 

 øvrige tilsammen og noget indknebet ved Basis. Det har 

 paa Undersiden nær Spidsen hos begge Kjøn en hos Hun- 

 nen større, hos Hannen betydelig mindre Aabning til Ud- 

 tommelse af Kjonsstoffene : hos Hannerne synes dog disse 

 Aabninger ganske at mangle paa IsteFodpar. Laarleddet 

 er af betydelig Størrelse, omtrent dobbelt saa langt som 

 hele Hoftepartiet. og gaar ved Spidsen paa den ydre Side 

 ad i en konisk, med 2 ulige lange Torner bevæbnet Fort- 

 sats. Hos Hunnen er dette Led mere eller mindre op- 

 svulmet paa Grund af de i dets Indre sig udviklende Æg 

 og har paaMidten 2 skraat overfor hinanden stillede tem- 

 melig stærke Torner. Iste Lægled er kortere end Laar- 

 leddet. hvorimod 2det er omtrent at samme Længde som 

 dette, begge af lineær Form og besatte med temmelig lige- 

 lig udviklede Torner. Tarsalleddet (se Fig. 3b) er sær- 

 deles lidet og meget bevægeligt forbundet med foregaaende 

 Led. Det er af uregelmæssig afrundel funn. stærkt ud- 

 randet i Enden og udåd springende frem i en smal, med 

 2 smaa Børster besat Lap; dets indre Kant er stærkt ud- 



reason to assume with Dohrn, that the 2 small spiniform 

 projections mentioned above, on the upper surface of the 

 frontal portion of the cephalic segment, represent a slight 

 rudiment of the chelifori, distinctly developed in the larva 1 , as 

 also an arched chitinous fillet on either side of the neck- 

 part of that segment (see fig. 3 a) indicates the place 

 whence, in the larvæ, the limbs corresponding to the palpi 

 had their origin. 



The false legs (fig. 3 f), which. as in the preceding 

 genus, are present in the males only (see figs. 3 c. 3 d), 

 have relatively a much more powerful development 

 than in that genus, and measure, fully extended, upwards 

 of half the length of the whole body. As in other Pyc- 

 nogonids, they are affixed on either side to a knob-shaped 

 projection issuing from the neck-part of the cephalic seg- 

 ment, immediately anterior to the first pair of lateral pro- 

 cesses of the body. and are bent in under the trunk. ex- 

 hibiting a marked S-shaped curve. They are composed of 

 only 7 joints, very unequal in length. and beset with short 

 spines. as a rule unguifbrm-recurvous, and distributed 

 without any order whatever. Concerning the relative size 

 of the joints, the Ist is comparatively short and thick. 

 whereas the 2nd is very considerably produced, nav more 

 than twice as long. The 2 succeeding joints, again, are a 

 good deal shorter, and. tåken together, hardly much Longer 

 than the 2nd; the 5th on the other hand is more elong- 

 ate, though shorter than the 2nd, and very much curved. 

 . The 6th joint is oval or elliptic in form, and has at the 

 end a bowl-shaped depression, from the bottom of 

 which the exceedingly small 7th, or terminal, joint is seen 

 to protrude. This joint is of triangular form and without 

 any ela w. hut provided on its inner margin with 2 short 

 spines, similar in character to the others affixed to those 

 limbs. 



The ambulatory legs (see fig. 3) are remarkably 

 slender. almost 3 times longer than the body. and beset 

 with scattered spines of somewhat unequal si/e. The 2nd 

 coxal joint is a good deal produced. more than twice as 

 long as the 2 others tåken together, and somewhat constricted 

 at the base. On the under surface. it has. near the extrem- 

 ity. in both sexes. an opening. — for the female comparatively 

 large, for the male much smaller, — to evacuate the genera- 

 tive matter; in the males, this opening would appear to 

 be entirely wanting on the Ist pair of legs. The femora] 

 joint is of considerable size. about double the length of 

 the whole coxal part, and protends at the point on the 

 outer surface as a conic projection, armed with 2 unequally 

 long spines. In the female, this joint is more or less 

 swollen, owing to the eggs in course of development within, 

 and exhibits moreover, placed obliquely opposite one 

 to the other. 2 rather powerful spines. The Ist tibia] 

 joint is shorter than the femoral joint, whereas the 2nd is 

 about of the same length; both are linear in form and beset 

 with well-nigb equably developed spines. The tarsus (see 

 fig. 3 b) is exceedingly small, and very movably connected 

 with the preceding joint. It has an irregular rounded 

 fonn. being deeply emarginated at the extremity, and
