der fra en teiiiiuelig tyli Stilk lober ud i tab-ige smaa Ende- 

 grene (Pl. V, Fig. 4). Disse o Led ere ganske glatte uden 

 nogen Fure melleni Leddene paa Rygfladen. De bagen- 

 forliggende Led ere livert ved dybe Furer delt i fire Einge 

 og paa den bagerste al' disse Einge sidde paa liver Side 

 to Borstebundter i to smaa koniske Knuder (T. V, Fig. 5). 

 Borsterne ere Haarliorster som i de forreste Led. men 

 kortere og færre eud paa disse ; desuden findes i det ventrale 

 Borstebundt paa alle Led et Antal kortere gaffelformede 

 Borster. der sidde i en egen Sæk. med to lidt udadboiede 

 Tænder (T. Y, Fig. (i). Den udkrængede Snabel er foldet, 

 men glat, uden Tænder (Fig. 2).

 Stat. 18. 31. 



Af dette Dyr var der et Exemplar fra Stat. 1 S. der 

 var iturevet paa Midten, og fra Stat. 31 fire Exemplarer. 

 af hvilke de .i vare hele og havde en Længde af 12'""' og 

 en Bredde af 1""". 



Kroppen er polseformig (T. Y. Fig. 12); hos et 

 Exemplar Forenden noget opdrevet (T. Y. Fig. 11). 



Hovedlappen tirkautet, Ijredere fortil end bagtil; de 

 to forreste Hjorner udtrukne i en kort Papille. ved Basis 

 en Grulje paa hver Side. i hvilken der sidder en liden 

 rund Papille (T. Y, Fig. 8). Iste Led borstelost. i de 

 følgende Led sidde paa hver Side to vifteformige Borste- 

 bundter i smaa mamilla-artige Knuder (T. Y. Fig. 13), 

 der efterhaanden Ijlive storre Imgover, indtil der fra det 

 12te bnrstebærende Segment optræder ordentlige Fodknu- 

 der, der ere delte i en dorsal og en ventral Gren. der 

 hver have en spidst fremragende Del, af hvilke Bor- 

 sterne komme frem, og. den dorsale opad, den ventrale 

 nedad, indenfor Spidsen et lidt fremi-agende Blad. der er 

 størst paa den dorsale Gren (T. Y. Fig. 14). Leddene 

 ere paa Forkroppen ved dybe Furer mere eller mindre 

 fuldstændigt afdelte i to Ringe; paa Bagkroppen ere Led- 

 dene delte i 3 Ringe. Furerne paa og mellem Leddene 

 blive paa Bagenden utydelige ; denne smalner jævnt af og 

 ender med et lidt opdrevet Analled. Anus terminal (T. Y, 

 Fig. 10); Forknuderne aftage i Storrelse paa de 4 — 5 sidste 

 Led og Borsterne blive kortere. 



Paa et Exemplar var Snabelen udkrænget og stod 

 som en kugleformig Blære frem under Hovedet, fuldkommen 



furnished on either side. posterior to the dorsal fascicle 

 of bristles, with a bi'anchia, which from a thickish stem 

 sends off numerous terminal branchlets, that on the 4th 

 being the largest (PI. Y. fig. 4). The five anterior seg- 

 ments quite smooth on the dorsal surface, without a trace 

 of intervening grooves or fuirows. The posterior segments 

 are each deeply sulcated. constituting four ring-shaped sec- 

 tions, the jjosterior of which is furnished on either side 

 with two fascicles of bristles composing two small conical 

 protuberances (PL Y. fig. n). These bristles are capilliform, 

 as in the anterior segments, but shorter and less numerous; 

 moreover, the ventral fascicle has on all the segments a 

 number of comparatively short, fiuxate bristles, in a peculiar 

 sac, each with two teeth bent slightly outwards (PI. Y, 

 fig. G). The evaginated proboscis folded, but quite smooth, 

 without a trace of teeth (fig. 2).

Stats. 18. 31. ^ . 



A specimen of this animal, mutilated in the middle, 

 came up at Station 1 8, and 4 specimens, 3 of them perfect, 

 measuring 12'""' in length and 1 '""' in breadth, were obtained 

 at Station 31. 



Body cylindrical (PI. Y. fig. 12); in one of the specimens 

 the anterior extremity was somewhat tumid (PI. Y, fig. 11). 



The lobe of the head quadrangular, broader anteriorly 

 than posteriorly ; the two anterior angles produced, forming 

 a wart-like prominence, with foveæ at the base, one on 

 either side, in which is seen a small round papilla (PI. Y, 

 fig. 8). Bristles wanting on the first segment; the succeeding 

 segments furnished on either side with two flabelliform 

 fascicles of bristles, placed in small mammillary protuberances 

 (PI. Y, fig. 13). which, posteriorly, continue to increase in 

 magnitude till, from the 12th bristle-bearing segment, they 

 form true i)edal protubei-ances, with a dorsal and a ventral 

 branch, each having a jiointed protrusive portion, fi'oin 

 which the bristles on the dorsal branch project upwards, 

 on the ventral, downwards; a little below the point is 

 seen a slightly projecting lamella, largest on the dorsal 

 branch (PI. Y. fig. 14), On the anterior portion of the 

 body, the segments are more or less bisulcated, forming 

 each two ring-shaped sections; on the posterior portion, 

 the segments constitute three sectional rings. The furrows 

 on and between the segments indistinct at the posterior 

 extremity, whicli gradually narrows, terminating in a 

 somewhat tumescent anal segment (anus terminal) (PI, Y, 

 fig, 10); the last four or five pedal protuberances diminish 

 in magnitude, the bristles, too, becoming shorter. 



In one of the specimens the proboscis was evaginated, 

 and had the appearance of a globular vesicle protruding
