med et stærkt chitiniseret knudeformigt Fremspring. Side- 

 hjørnerne af Hovedsegmentet mindre uddragne end hos A. 

 echinata. Øieknuden lige opadrettet. pyramidal, endende 

 i en konisk Spids, Lindserne omtrent ved Midten. Snabelen 

 stærkt nedådrettet, neppe mere end halvt saa lang si nu 

 Legemet. Saxlemmerne noget mere end halvt saa lange 

 som Snabelen, Skaftet kølleformigt, uden nogen tydelig 

 dorsal Portsats, Endedelen uregelmæssig oval. Følerne 

 8-leddede, 2det Led kortere end 4de, Endedelen omtrent 

 af dette sidstes Længde. Gangfødderne neppe dobbelt saa 

 lange som Legemet, uden tydelige Pigge, men med spredte 

 Haar. Iste Hofteled oventil ved Enden forsynet med en 

 knudeformig Fortsats, alle Hofteled hos Hannen temmelig 

 tæt haarede; Fodleddet forholdsvis endnu kraftigere end 

 hos foregaaende Art, noget fortykket paa Midten; Ende- 

 kloen over halvt saa lang som Fodleddet, Bikløerne sær- 

 deles smaa. Legemets Længde 1.50"""; Spandvidde li""". 



Bemærkninger. Jeg antager det for rimeligt. at 

 dette er Hodge's Achelia lævis, men Beskrivelsen ei- altfor 

 ufuldstændig til med fuld Sikkerhed at afgjore om saa er 

 Tilfældet. Arten er imidlertid i begge Kjøn meget let at 

 kjende fra foregaaende, navnlig ved den fuldstændige Sam- 

 menvoxning af alle Kropssegmenter, ved Øieknndens Form 

 og Gangføddernes Mangel af Pigge. Ogsaa i Saxlemmer- 

 nes og Følernes Bygning er der, som af ovenstaaende 

 Diagnose vil sees, vel udprægede Differentser. Forudeu 

 Han og Hun har jeg af denne Art ogsaa havt Anledning 

 til at undersøge ganske unge Individer med tydeligt cheli- 

 forme Saxlemmer. 



Beskrivelse. Legemets Længde er hos den fuldt 

 udvidlede Hun neppe mere l 1 //"", med en Spandvidde af 

 6""". Hannen er ubetydelig større. 



I ydre Habitus har denne Art ise Pl. XIII, Fig. 2, 

 2 a) stor Liglied med foregaaende. Kroppen (Fig. 2 b, 

 2 e) er dog om muligt endnu noget plumpere og i høi 

 Grad udmærket derved, at samtlige Segmenter er fuld- 

 stændig sanimenvoxne, uden at det mindste Tegn til nogen 

 Tværsuturer kan opdages hverken oventil eller nedentil. 

 Sidefortsatserne er forholdsvis noget kortere end hos fore- 

 gaaende Art og har ved Enden oventil, som hos denne. 2 

 Fortsatser; men disse er her meget ulige, idet den forreste 

 er meget liden, tilspidset og paa Toppen forsynet med en 

 kort Børste, medens den bagerste har Formen af en tem- 

 melig stor og stærkt chitiniseret konisk Knude uden ter- 

 minal Børste. Hovedsegmentet er, som hos foregaaende 

 Art, fortil næsten lige afkuttet, men har Sidehjornerne 

 betydelig mindre fremspringende. Halesegmentet er af 

 lignende Udseende som hos A. echinata. 



Øieknuden (Fig. 2 d) er lige opadrettet, stærkt 

 ophoiet og af pyramidal Form, fra Midten af successivt 



setiferous process, and posteriorly with a strongly chitinised 

 Dodiforra protuberance. Lateral corners of the cephalic 

 segment less drawn out than in A. echinata. < (cular 

 tubercle directed straightly upwards. pyramidal, termin- 

 ating in a conical point; the lenses situated nearly in 

 the middle. Proboscis directed strongly downwards, 

 scarcely more than half the length of the body. Cheli- 

 fori somewhat more than half as long as the proboscis, 

 scape claviform, without any distinct dorsal process, 

 terminal part irregularly oval. Palpi 8-jointed, 2nd 

 joint shorter than the 4th, terminal part about same 

 length as the last-named. Ambulatory legs scarcely 

 twice as long as the body. without distinct spim-s but 

 with scattered setæ, Ist coxal joint furnished' at the end 

 above with a nodiform process. all the coxal joints 

 in the male rather densely setous; propodal joint, rela- 

 tively still more powerful than in the preceding species, 

 somewhat tumeficated at the middle; the terminal claw 

 more than half as long as the propodal joint, auxili- 

 ary claws particularly small. Length of the body L.50 

 extent 6""". 



Remarks. I suppose it to be probable that this is 

 Hodge's Aclielia lævis. but the description is much too in- 

 complete to enable this to be determined with perfect 

 certainty. The species is, however, in both sexes. very 

 easy to distinguish from the preceding one, particularly 

 by the perfect accretion of all the segments of the body, 

 by the form of the ocular tubercle, alid the absence of 

 spines on .the ambulatory legs. In the structure of the 

 chelifori and palpi also, as will be observed ironi the 

 above diagnosis. there are marked differences. Besides 

 male and female, I have, also, of this species, had the 

 opportunity of investigating quite young individuals with 

 distinct forcipated chelifori. 



Description. The length of the body in the fully 

 developed female is scarcely more than 1'/-""" with an 

 extent ot 6""". The male is inconsiderably larger. 



In external habit this species has (see Pl. XIII, 

 fig. 2, 2 a) great resemblance to the preceding one. The 

 trunk (fig. 2 b, 2 c) is, however. if possible, still more 

 thick-set, and in an eminent degree remarkable liv the 

 fact that all the segments are completely coalesced. without 

 it being possible to observe the least trace of any trans- 

 versal sutures either above or below. The lateral pro- 

 cesses are relatively somewhat shorter than in the pre- 

 ceding species. and, like it, have. at the extremity above, 

 2 processes. but these are here verv unlike, inasmuch 

 that the foremost one is very small, pointed, and at the 

 top furnished with a short bristle, while the posterior one 

 has the shape of a pretty large and strongly chitinised 

 conical nodule without a terminal bristle. The cephalic 

 segment is. as in the preceding species. almost straightly 

 truncated in front, but has the lateral corners considerably 

 less prominent. The eaudal segment resembles in appear- 

 auce that of A. echinata. 



The ocular tubercle (fig. 2 d) is directed straight 

 upwards, strongly protuberant, and pyramidal in form,
