 Artscliaracter. Legemet af undersætsig Form, fint 

 laaddent oventil, med Sidefortsatserne tæt sammentrængte 

 og kortere end Kroppens Brede. Hovedsegmentet omtrent 

 saa langt som de 3 følgende Segmenter tilsammen, Halsen 

 særdeles kort og tyk, Pandedelen temmelig bred, Haleseg- 

 mentet noget opadrettet. Øieknuden forholdsvis lav, stumpt 

 tilrundet. Snabelen kortere end Hovedsegmentet. Sax- 

 lemmerne smaa, tæt og kort haarede, Haanden betydelig 

 kortere end Skaftet, med Palmen jevnt bred og længere 

 end Fingrene, der med samme danner en udpræget Vinkel. 

 Følerne ualmindelig smaa, 2det Led størst, sidste Led af- 

 rundet ovalt, neppe kortere end næstsidste. De falske 

 Fodder omtrent af Legemets Længde, Randtornerne smaa, 

 noget krummede og utydeligt saugtakkede. Gangfødderne 

 kort laadne overalt, ualmindelig robuste, noget sammen- 

 trykte, neppe 3 Gange længere end Legemet, 2det Lægled 

 jevnt bredt, omtrent 2 1 /., Gange længere end det terminale 

 Afsnit, Tarsalleddet ligesaa bredt som langt, Fodleddet 

 omtrent 3 Gange saa langt, noget opsvulmet i sit basale 

 Parti, med en Rad af circa 8 stærke, udåd i Længde til- 

 tagende Torner i Inderkanten; Endekloen halvt saa lang 

 som Fodledflet, stærkt krummet; Bikløerne vel udviklede, 

 af Endekloens halve Længde. Legemets Længde 6""" ; 

 Spandvidde 33""". 



Bemærkninger. At den her omhandlede Form er 

 identisk med den af Krøyer under ovenstaaende Navn be- 

 skrevne og afbildede Art, antager jeg for givet, og dette 

 bekræftes ogsaa ved den nylig af Dr. Hansen meddelte, 

 temmelig udførlige Diagnose. Derimod holder jeg det for 

 meget tvivlsomt, hvorvidt Krøyers og Fabricius's Art er 

 den samme, og maa fremdeles fastholde, at der er vel saa 



hand, N. hirtum Kroyer, and on the other, N. macronyx 

 G. 0. Sars. Of exotic forms, N. brevicaudatum Miers 

 (hispidum Hoek), from Kerguelen, belongs unquestionably 

 to the same genus. The number of species amounts there- 

 fore, at present, to not less than 5.

 Speciflc Characters. Body thickset in form, delicately 

 pubeseent above, with the lateral processes closely crowded 

 together and shorter than the trunk is broad. Cephalic 

 segment about as long as the 3 following segments tåken 

 together, neck exceedingly short and thick, frontal part 

 rather broad. caudal segment directed somewhat upwards. 

 Oculiferous tubercle comparatively low, obtusely rounded. 

 Proboscis shorter than the cephalic segment. Chelifori 

 small, densely and shortly hispid, hand considerably shorter 

 than the scape, with the palm uniformly broad, and longer 

 than the fingers, which make with the former a prominent 

 angle. Palpi remarkably small, 2nd joint largest, last 

 joint rounded oval, hardly shorter than the penultimate 

 one False legs about the length of the body, marginal 

 spines small, somewhat bent and indistinetlv serrated. 

 Ambulatory legs everywhere shortly hispid, uncominonly 

 robust, somewhat compressed, scarcely 3 times longer than 

 the body, 2nd tibial joint uniformly broad, about two and 

 a half times longer than the terminal section, tarsal joint 

 as broad as long, propodal joint about 3 times as long, 

 somewhat swollen in its basal part, with a row of about 

 8 strong spines on the inner edge, increasing in length 

 outwards; terminal claw half as long as the propodal 

 joint, strongly hent; auxiliarv claws well developed, half 

 the length of the terminal elaw. Length of body 6""" ; 

 extent 33'"'". 



Remarks. That the form treated of here, is identical 

 witli the spreies dcscrilicd and figured by Kroyer under 

 the above name. I assume to be certain, and the rather 

 full diagnosis lately given by Dr. Hansen tends to establish 

 this. On the other hand, I regard it to be highly 

 doubtful whether Kroyer's and Fabricius's species is the 

 same form, and must still maintain, that there is quite as
