geode tilsammen. Bisvøben er forholdsvis liden og bestaar 

 kun af 3 Led. 



2det Par Følere l Fig. 3 b) er omtrenl af samme Længdé 

 som Iste Pai og har Skaftets næstsidste Led længst. Svøben 

 er neppe I engere end paa Iste Par og bestaar omtrent af 



il, i samme Antal Led. 



Munddelene dækkes ikke ganske til Siderne al' Iste 

 Par Epimerer, men rager for en Del ti- i t frem nedenfor 

 samme (se Fig- 31- I deres Bygning er der kun liden 

 Forskjel at bemærke fra de 2 hengere nedenfor beskrevne 

 Arter. 



Kindbakkerne (Fig. 3 c) liar Tyggeknuden vel udviklet 

 og temmelig stærkl fremspringende. Palpen er tiestet i 

 Hoide med denne og ei' temmelig stor. med sidste Led 

 nogel udvidet paa Midten og tæt børstebesat. 



Iste Par Kjæver (Fig. 3 d) har den midterste Gren 

 (den egentlige Tyggelap) krattigt udviklet og bevæbnel med 

 stærke Torner. Den indre Lap er derimod ganske liden 

 og ved Spidsen forsynet med -l cilierede Børster. Palpen 

 overrager kun lidet den midterste Lap og er paa Enden 

 af det sammentrvkte sidste Led forsynet med en Rad at' 

 korte Torner. 



2det Par Kjæver (Fig. 3 e) bestaar som sædvanlig! 

 at ■! fra en fælles Basaldel udgaaende Lapper, hvoraf den 

 indre er noget mindre end den ydre, begge tæt børste.be- 

 satte. 



Kj.evetodderne i Fig. '■'< /') viser tien sædvanlige Byg- 

 ning. Den ydre Tyggelap er temmelig stor, af skjævt oval 

 Form og ved det indre Hjørne forsynet med en Del Torner. 

 Palpens sidste Led er meget smalt, lineært og kun sparsomt 

 børstebesat, Endekloen forholdsvis svag. 



Iste Fodpar (Fig. 3//> er temmelig nndersætsigl bygget 

 og ufuldkomment subcheliformt ligesom hos Arterne af 

 Slægterne Lysianassa og Socarnes. Sidste Led eller Haan- 

 den er omtrent saa langt som de ■> foregaaende Led til- 

 sammen og afsmalner jevns mod Enden uden at vise nogen 

 tydeligt begrændset Griberand. 



2det Fodpar (Fig. 3 h) viser den lor Familien char- 

 acteristiske spinkle Bygning og hai- de :: ydre Led tat 

 haarede og Endekloen rudimentær. 



De -J følgende Fodpar (Fig. 3 i) udmærker sig især 

 ved den usædvanlige Form af Endekloen. Denne er tem- 

 melig t\k. dolkformig og neppe mærkeligt krummet. 



I»- 3 bagre Fodpar (se Fig. 3) har som sædvanligt 

 Hofteleddet pladeformigt udvidet, af oval Form og i den 

 bagre Haud utydeligt saugtakket. Sidste Par (Fig. 3 k) 

 udmærker sig dog i hoi Grad derved, at det nedre bagre 

 Hjørne af dette Led er udtrukket i en skarp dolkformig 

 og skraal bagudrettet Fortsats, ligesom en SpOre. 



the Ist being, as usual, largest, and about equal in length 

 to the 2 succeeding ones, tåken together. The secondary 

 Hagellum is comparatively small, and consists of only 3 

 articulations. 



The 2nd pair of antennæ (fig. 36) are abont of the 

 same lengtb as the Ist pair. and have the penultimate joint 

 of the peduncle longest. The flagellum is scarcely at all 

 longer than that on the Ist pair. and consists about of the 

 same number of articulations. 



The oral appendages are not quite eovered at the 

 sides liv the Ist pair of epimera, projecting as they do. in 

 part. freely forward 1 belov? them (see iig. 3). ln structure, 

 the\ exhibit but little difference from those in the 2 species 

 described below. 



The mandibles (fig. 3 f) have the molar protuberance 

 well developed and rather prominently projecting. The palp, 

 attached at the same height as the protuberance. is com- 

 paratively large, with the last joint somewhat dilated in the 

 middle and densely beset with bristles. 



The Ist pair of maxillæ (hg. :s th have the medial 

 brancb (the true masticatory Lobe) powerfully developed. 

 and armed with strong spines. The inner lobe, on the 

 other hand. is quite small, and furnished at the point with 

 2 ciliated bristles. The palp projects but little beyondthe 

 medial lobe, and is furnished at the extremih of the eoni- 

 pressed terminal joint with a row of short spines. 



The 2nd pair of maxillæ (fig. 3 e) consist as usual 

 of -J lolies proceeding from acommon basal part. of which 

 the inni']- is somewhat smaller than the outer — both densely 

 beset with bristles. 



The maxillipeds (rig. 3 f) exhibit the usual structure. 

 The outer masticaton lobe is rather large, obliquely oval 

 in form. and at the innér corner armed with a number of 

 spines. The last articulation of the palp is exceedingly 

 slender, linear, and but sparingly beset with bristles — the 

 terminal claw comparatively weak. 



The Ist pair ot legs (fig. •"> //) are rather thickset in 

 structure. and imperfectly subcheliform, as in the spedes 

 of tlie genera Lysianassa and Socarnes. The terminal ar- 

 ticulation, or hand. is about as long as the 2 preceding 

 articulations tåken together, and tapers gradually towards 

 the end. without exhibiting any distinctly defined palm. 



Tlie 2nd pair of legs (fig. 3 h) exhibit the slim. fragile 

 structure characteristic of the family; they have the outer 3 

 articulations thickly eovered with hair and the terminal 

 claw rudimentary. 



The 2 succeeding pairs of legs (fig. 3 i) are disting- 

 uished more especially by the unusual form of the terminal 

 claw. whidi is rather thick, dagger-shaped, aud well-nigh 

 imperceptibly curved. 



The 3 posterior pairs ot' legs (see rig. 3) have, as 

 usual. the basal joint lamelliform-dilated, oval in structure. 

 and. along the posterior margin, indistinctly serrate. The 

 last pair (rig. 3 /,■) are highly characterized by the lower 

 posterior corner of the said joint being drawn out as a 

 sharp, dagger-shaped projection. or. as it were, spur, di- 

 rected obliquely backward.
