Bemærkninger. Nærværende Art maa, som den forst 

 opdagede. betragtes som Typen for Slægten. Den er vel 

 adskilt fi a de 3 af Hoek fra Challenger Expeditionen be- 

 skrevne Former ved de korte Sidefortsatser, Øieknudens 

 Form og Stilling, den enorme Udvikling af Snabelen, de 

 tæt haarede Gangfødder og Forholdet af disses 2 sidste 

 Led. 



Beskrivelse. Formen er (se Pl. XIV, Fig. 2) for- 

 holdsvis meget spinkel, saavel hvad Kroppen som Lein- 

 merne angaar. Selve Kroppen (Fig. 2 a, 2 b, 2 c) er af 

 smal cylindrisk Form og. ovenfra eller nedenfra seet, næsten 

 overalt af ens Brede. Seet ira Siden (Fig. 2 c) viser den 

 sig noget bredere paa Midten og mere' eller mindre krum- 

 met. Segmenterne er meget skarpt afsatte fra hinanden, 

 og den bagre Rand paa de 3 forreste er tydeligt hævet 

 oventil; umiddelbart foran Randen har ethvert af disse 

 Segmenter et lige opadrettet tilspidset Fremspring. Side- 

 fortsatserne er adskilte ved brede Mellemrum og ikke af 

 nogen betydelig Længde. idet de neppe overgaar Legemets 

 Brede. Enhver af dem har oventil ved Enden et kort 

 tandformigt Fremspring og er i Kanterne besatte med korte 

 Haar. ' Selve Kroppen er derimod saagodtsom nogen. eller 

 kun forsynet med yderst smaa, mikroskopiske Torner. 

 Hovedsegmentet er af betydelig Størrelse, adskilligt længere 

 end de 2 følgende Segmenter tilsammen, og har en tem- 

 melig lang cylindrisk Hals, der ved Basis til hver Side 

 viser en ganske svag Udbugtning til Fæste for de falske 

 Fodder. hvorimod egentlige Halsfortsatser mangler. Pande- 

 delen udvides ganske successivt mod Enden, som er tem- 

 melig bred og tvært afkuttet. Halesegmentet (Fig. 2 t), 

 der som hos foregaaende Slægt er tydeligt articuleret til 

 sidste Kropssegment, er særdeles smalt, eylindriskt eller 

 kun ganske svagt fortykket i sit ydre Parti, og noget 

 nedadkrumniot (se Fig. 2 c). Det er kun forsynet med 

 megel smaa, spredte Haar og viser i Enden en tydelig 

 spaltformig Analaabning. 



Øieknuden (se Fig. 2 a, 2 b) er. uligt hvad Tilfældet 

 er med de af Hoek beskrevne Arter, beliggende helt fortil 



developed individuals. perticularly small, trinngular, with a 

 short dentate nodule as a rudiment of the mobile finger. 

 Palpi, straightly extended, almost 5 times longer than the 

 chelifori, 5th joint only a little skorter than the 3rd. ter- 

 minal part not quite so long, 2nd joint longest. False 

 legs in male longer than the trunk. Ist joint of the 

 terminal part almost as long as all the others together. 

 Ambulatory legs about twice as long as the body. closely 

 beset with short setæ, tarsal joint verv short. propodal 

 joint in female linear, with short spines on the inner 

 margin, in the male broader and more compressed and 

 armed with a series of 16 — 18 considerably strenger spines; 

 terminal claw in female half the length of the propodal 

 joint; in male considerably larger. Length of the body. 

 exclusive of the proboscis. 7"""; extent 32'"'". 



Remarks. The present species must. as the first 

 discovered, be regarded as the type of the genus. It is 

 well distinguished from the 3 forms from the Challenger 

 Expedition described by Hoek, by the short lateral pro- 

 cesses, the form and position of the ocular tubercle, the 

 enoi - mous development of the proboscis, the densely setous 

 ambulatory legs and the relations of their 2 terminal 

 joints. 



Description. The form (see Pl. XIV, fig. 2) is rel- 

 atively very slender, both as regards the trunk and the limbs. 

 The trunk itself (fig. 2 a, 2 b, 2 c) is narrow cylindric 

 in form, and, viewed either superiorly or inferiorly, it is 

 almost everywhere uniform in breadtb. Viewed laterally 

 (fig. 2 c) it shows itself to be somewhat broader at the 

 niiddle and more or less bent. The segments are very 

 sharply defined from each other, and the posterior margin 

 on the 3 foremost ones is distinctly raised above ; immedi- 

 ately in front of the margin each of those segments has 

 a pointed prominence directed straight upwards. The 

 lateral processes are separated by broad intervals and are 

 not of any considerable length, as they scarcely exceed 

 the breadth of the body. Each of them has above, 

 at the extremity, a short dentiform prominence and is 

 beset with short setæ on the edges. The trunk itself is. 

 on the other hand, almost quite bare, or only furnished 

 with extremely minute microscopical spines. The cephalic 

 segment is of considerable size, considerably longer than 

 the 2 succeeding segments together, and has a pretty long 

 cylindrical neck which. at the base, on each side, shews 

 a quite faint bulging for the attachment of the false legs. 

 whereas real cervical processes are awanting. The frontal 

 part is quite progressively expånded towards the extremity. 

 which is pretty broad and abruptly truucated. The caudal 

 segment (fig. 2 t), which, as in the preceding genus, is 

 distinctly articulated to the last segment of the trunk, is 

 particularly narrow. cylindrical. or only quite faintly tume- 

 ficated in its exterior portion and somewhat bent down- 

 wards (see fig. 2 cj. It is only furnished with very small, 

 scattered setæ, and exhibits at the extremity a distinct 

 fissured anal aperture. 



The ocular tubercle (see fig. 2 a. 2 b) is. unlike what 

 is the case in the species described by Hoek, situated quite
