Bemærkninger. ^om ovenfor bemærket. kan jeg ikke 

 v;ere enig med Wilson og tiere senere Forskere, naar de 

 anser denne Form kun som en "\ arietet af N. grossipes. 

 Wilson selv har neppe engang havt for sig den rette 

 Krøyerske Art, og at senere Forskere aden videre bar 

 adopteret denne Forfatters Opfatning, maa bero paa en 

 mindre indgaaende Undersøgelse af de her omhandlede For- 

 mer. Som af ovenstaaende Diagnose vil sees. viser nemlig 

 nærværende Art. formlen i Længdeforholdet af Halsen og 

 de 2 ydre Fodled. ogsaa vel udprægede Forskjelligheder i 

 Saxlemmernes og Følernes Bygning, hvilket synes at maatte 

 sætte dens specifiske Forskjel fra N. grossipes udenfor al 

 Tvivl. Den af Hoek fra Cballenger Expeditionen beskrevne 

 Form. der paa Planeheii er benævnt N. armatum, synes 

 mig, ialfald at dømme eiter Følernes Udseende, ubetinget 

 at maatte henføres til nærværende Art, og ikke. som Hoek 

 i Texten anfører, til N. gross/pes. 



Beskrivelse. Legemets Længde bos de største af 

 mig undersøgte Exemplarer gaar op til 9 1 / 2 """, med en Spand- 

 vidde af 95""", og denne Art opnaar saaledes en meget an- 

 selig Størrelse. 



Legemsformen er (se Pl. VI, Fig. 3), som ogsaa af 

 K røyer fremstillet, særdeles spinkel, og navnlig udmærker 

 Fødderne sig ved sin ualmindelige Længde og Tyndhed. 

 Selve Kroppen (Fig. 3 a, 3 b) er af smal cylindrisk Form. 

 med Sidefortsatserne stærkt forlængede og skilte ved meget 

 brede Mellemrum; de udgaar her fra den bagre Del af de 

 respective Sementer, medens deres Basis hos foregaaende 

 Art indtager, ialfald paa de 2 midterste Segmenter, omtrent 

 Midten af Sidefladerne. Hovedsegmentet er af betydelig 

 Længde. vel saa langt, som de 3 følgende Segmenter til- 

 sammen, og udmærket ved den særdeles smale og forlængede 

 Hals. der er dobbelt saa lang som Pandedelen ; denne sidste 

 er derimod ber kjendelig mindre end bos N. grossipes. 



Øieknuden er (se Fig. 3 a) paa Grund af Halsens 

 betydelige Længde ber niere end 3 Gange længere fjernet 

 fra Panderanden end fra Hovedsegmentets bagre Rand 

 Den er stærkt opbøiet, lige opadrettet, og gaar i Enden ud 

 i en skarn konisk Spids (Fig. 3c). Lindserne er vel ud- 

 viklede og forholder sig som hos foregaaende Art. 



terminal part shorter than the latter joint, marginal spines less 

 elongated than in the preceding species. Ambulatory legs re- 

 markably slender. from 4'.^. to 5 times longer than the body; 

 tarsal joint greatly prolonged and slender: propodal joint 

 relatively slunt, often hardly half as long as tarsal joint, 

 straight, inner edge armed with 7 — 8 elongated spines; 

 terminal elaw short and powerful, scarcely half as long as 

 tbe propodal joint; auxiliary claws uncommonly elongated, 

 a I ii mt -,,, as long as the terminal elaw. Colour yellowish 

 white, with broad, orange-coloured transversal bands. 

 Length of bodj 9 1 , . ' . extent 95"™. 



Remarks. As stateil above, I do not agree with Wil- 

 son and several utber hiter naturalists in regarding this form 

 as ouly a variety of N. grossipes. Indeed, Wilson himself 

 has hardly had before hini the true Kroyer species, and 

 that later naturalists should so readily have adopted Mr. 

 \\'ilson's view, must. I think. arise from a less thorough 

 examination of the forms treated of here. As will appear 

 from the above diagnosis, tbe present species exhibits, not 

 only in the longitudinal relations of the neck and tbe - outer 

 leg-joints, hut also in the structure of the chelifori and 

 palpi. well marked differences, which would seem to place 

 its specific distinction frem N. grossipes beyond all doubt. 

 The fonn described by Hoek from the Callenger Expedition, 

 designated N. armatum in the plate, should, I think, to 

 judge ironi the appearance of the palpi, unquestionably be 

 referred to the present species. and not. as Hoek in the 

 text says, to X. grossipes. 



Description. The length of the body in the largest 

 specimens I have examined reaches 9 1 /./"'". the extent 

 95 . and this species attains. therefore. a very consider- 

 able size. 



The body (see Pl. VI, fig. 3i is. as represented 

 too. by Kroyer, exceedingly slender. and the legs are. in 

 particular, distinguished by their remarkable length and 

 slimness. The trunk itself (fig. 3 a, 3 b) is narrow cyl- 

 indrical in form. with the lateral processes exceedingly 

 elongated and marked off" by verv broad interspaces; they 

 issue, in this animal, from the posterior part of the respec- 

 tive segments, whereas their base in the preceding species 

 occupies. .at least on the 2 medial segments, about the 

 niiddle of the lateral surfaces. The cephalic segment is of 

 considerable length. quite as long as the 3 sueceeding seg- 

 ments tåken together, and characterised by the exceedingly 

 slender and elongated neck, which is double the length of 

 the frontal part; the hitter, on the other band. is ap- 

 preciably smaller than in N. grossipes. 



The oculiferous tubercle (see rig. 3 a), is here, owing 

 to the eonsiderable length of the neck. more than 3 times as 

 far from the frontal margin as from the posterior edge of 

 the cephalic segment. It is exceedingly protuberant, directed 

 straight upwards, and runs out at the end to a sharp 

 conical point (fig. 3 c). The lenses are well developed and, 

 otherwise, are as in the preceding species.
