agtige [ntegumenter sig forsynede mod talrige smaa ellips- 

 oidiske Legemer (sr Fig. 2 d). 



Øieknuden har Formen af et høit. koniskt tilspidset 

 og lidt foroverbøiet Fremspring (se Fig. 2 c), der. som 

 hos foregaaende Art. mangler ethvert Spor af Pigment 

 eller Synselenienter. 



Snabelen (se Fig. 2 a, 2 b, 2 c) er vel saa lang som 

 den øvrige Del af Legemet, naar Halesegmentet fraregnes, 

 op lige fortilstrakt, nøiagtig i Kroppens Axe. Den er af 

 smal cylindrisk Form. neppe bredere end Kroppen, og har 

 paa Midten en svag men tydelig Opsvulmning. Spidsen 

 er noget skraat afstumpet, med den ovre Læbedel skydende 

 noget udover de 2 øvrige (se Fig. 2 b). Selve Mundaab- 

 ningen har et lignende Udseende som hos foregaaende Art. 



Af Saxlemmer var hos ingen af de indsamlede Exem- 

 plarer nogetsomhelst Spor at opdage. Det maa imidlertid 

 her anmærkes, at Hoek hos 3 af de 8 under Tritoifs 

 Expedition indsamlede Exemplarer fandt tydeligt udviklede 

 og temmelig stærkt forlængede, skjondt overordentlig tynde 

 Saxlemmer, og at efter samme Forsker disse Lemmer ogsaa 

 var tilstede hos et Exemplar af den nærstaaende Art, C. 

 gradlis. Rimeligvis har ingen af disse saaledes udrustede 

 Exemplarer været fuldt udviklede. Det er imidlertid hoist 

 mærkværdigt, at disse Lemmer, der er fælles for alle Pyc- 

 nogonideer i Larvelivet. her bibeholdes og udvikles videre 

 lipe til Dyret paa det nærmeste er udvoxet, for saa ganske 

 at forsvinde. Hvorvidt dette gjælder blot de 2 lier riævnte 

 Arter eller samtlige Arter af Slægten. er endnu ikke til- 

 strækkelig oplyst. 



Følerne (se Fig. 2 a. 2 b, 2 c) er i alt væsentligt 

 af en lignende Beskaffenhed som hos foregaaende Art og, 

 lige udstrakte, næsten 1 j i Gang længere end Snabelen. 

 Leddenes indbyrdes Længdeforhold stemmer ogsaa idethele 

 temmelig vel overens med samme hos hin Art. naar und- 

 tages de 3 sidste Led. Af disse er nemlig (se Fig. 2 e) 

 det Iste Led ualmindelig kort, næsten skaalformigt. og 

 skraat afskaaret i Enden, dannende nedad en afrundet 

 fremspringende Lap, medens de 2 øvrige er af sædvanlig 

 Form og indbyrdes næsten af ens Størrelse, eller det 

 sidste lidt længere og smalere end næstsidste. 



De falske Fødder (se Fig. 2 a) er spinkle og for- 

 Længede, lige udstrakte betydelig længere end det hele 

 Legeme, og stemmer idethele i sin Bygning temmelig noie 

 overens med samme hos foregaaende Art. 4de Led (er 

 dog her forholdsvis noget større og neppe kortere end 5te. 



Gangfødderne (se Fig. 2) udmærker sig ligeledes ved 

 sin overordentlig spinkle og forlængede Form. idet de. lige 

 udstrakte, er niere end 3 Gange længere end Legemet. I 

 Henseende til det indbyrdes Længdeforhold af Leddene er 

 dei' imidlertid kun liden Forskjel mellem de 2 Arter, naar 

 alene undtages. at de 2 sidste Led (se Fig. 2 f) er af 



ous integuments show themselves to be furnished with 

 numerous small ellipsoidal bodies (see fig. 2 d). 



The ocular tubercle has the form of a high eonically 

 pointed prominence bent slightly forward (see fig. 2 c). 

 which. as in the preceding species, is deficient in the 

 slightest trace of pigment or visual elements. 



The proboscis (see fig. 2 a, 2 b, 2 c) is fully as long 

 as the rest of the body. vhen the caudal segment is de- 

 ducted. and. directed straight forward, lies exactly in the axis 

 ot the trunk. It is narrow, cylindric in form, scarcely 

 broader than the trunk. and at the middle has a faint but 

 distinct tumefication. The point is somewhat obliquely 

 truncated, with the superior labial part projeeting a little 

 beyond the 2 others (see fig. 2 IV). The oral aperture 

 itself is similar in appearance to that of the preceding 

 species. 



- Of chelifori. tlicre was not in any of the specimens 

 obtained a trace discoverable. It must be noted here. 

 however. that Hoek. in 3 out of the 8 specimens collected 

 during the ..Tritons" Expedition. observed distinctly devel- 

 oped and pretty greatly elongated, although extremely thin 

 clielifori. and that according to the same naturalist those 

 limbs were also present in a specimen of the closely 

 related species C. gradlis. Probably none of the spec- 

 imens thus equipped have been fully developed. It is, 

 however, highly remarkable that those limbs. which are 

 common to all Pycnogonids in the larval state, are here 

 maintained and further developed until the animal is 

 almost fully grown, and then quite disappear. Whether 

 this is the case only with the 2 species named here. or 

 affects all species of the genus, is not yet sufficiently 

 elucidated. 



The palpi (see figs. 2 a. 2 b, 2 c) are, in all es- 

 sential respects, similar in character to those of the pre- 

 ceding species and, straightly extended, almost 1 / 2 longer 

 than the proboscis. The mutual longitudinal relations of 

 the joints correspond. upon the whole, pretty well with 

 the same in that species, with the exception of the 3 

 last joints. Of these the Ist (see fig. 2 e), especially, is 

 uncommonly short. almost cupuliform. and obliquely trunc- 

 ated at the extremity, forming downwards a rounded pro- 

 minent lobe, while the 2 others are of the usual form, and 

 mutually about equal in size, or the ultimate one perhaps 

 a little longer and narrower than the penultimate one. 



The false legs (see fig. 2 a) are slender and elongate, 

 straightly extended considerably longer than the entire 

 body. and correspond in their structure. upon the whole. 

 pretty closely with the same features in the preceding 

 species. The 4th joint is. however. relatively. somewhat 

 larger and scarcely shorter than than the oth. 



The ambulatory legs (se fig. 2) distinguish themselves, 

 also, by their extremely slender and elongate form. as they. 

 straightly extended. are more than 3 times longer than 

 the body. In regard to the mutual longitudinal relations 

 of the joints, there is. however. only ^little divergency 

 between the 2 species. with the exception. only. that the
