Ueune Auuulide har stor Liglu>cl mod Myriochele Heeri, 

 Mgrn. ; den er dog betydeligt tyndere end denne og har 

 ei som denne tine Tagger henimod Spidsen at' Haarborsterne. 

 Malnigrens Tegning af Hageborstcrno mangler ogsaa den 

 Foi-tykkelse i Enden af Stilken, der bærer den ovre Ende, 

 som tindes hos det ovenfor beskrevne Dyrs Hageborster. 

 Jeg har derfor troet at burde optbre don som en ny Art 

 af den samme Slægt.

Rorene vel '/-''"'" tykke, beståa af Slam, besat med 

 Smaasten og lange Kiselnaale som af en Svamp (T. VI, 

 Fig. 15). Intet Dyr kunde faaes helt ud; paa et saaes 

 en afruudet Ende og Ijag denne 3 Segmenter med Kapil- 

 lorbnrster alene (T. VI, Fig. 13); dette har formodentlig 

 været en Forende, skønt Mundens Bebggenhed ei kunde 

 opdages. Paa alle de folgende Led ogsaa Hageborster, 

 der sidde 8 — 10 jævnsides i Tori; disse ere meget lange 



og naa næsten sammen 



paa Bugfladen. 



Haa;eborsterne 



have to Tagger i Spidsen (T. VI, Fig. 14), og denne 

 er svagt krummet som hos M. Sarsn; men Borsterne vare 

 ikke sammensatte som hos denne. Ligesom hos M. Sarsii 

 findes der i hvert af de længere Segmenter to Sække, der 

 synes at udmunde mellem Torus og Kapillærborstebundtet 

 (T. VI, Fig. 13, fl).

Legemet rundt, Bagkrop])en lidt tiadtrykt, ender 

 spidst. Anus terminal (T. VII, Fig. 23). Bugfuren kun 

 synhg paa Bagkroppen. Kraven uedboiet i hele Sidepartiet 

 med fortil og bagtil opretstaaende Flige, mellem hvilke der 

 tindes temmelig dybe Indsnit. Paa Iste Segment kun 

 kajiillære Børster, paa de 7 folgende ogsaa Hageborster 

 ventralt stillede. De kapillære Borster 2 Slags: lange, 

 tynde med en smalt bræmmet Spids (T. VII, Fig. 25) 

 og korte subspathulerede (T. VII, Fig. 24), ligehgt bredt 

 bræmmede nedenfor den korte Spids. Hagebørsterne bise- 

 riale, forreste Rad med en lang, tynd Spids paa en lang 

 krummet Stilk (T. VII, Fig. 2(3, «) anden Rad avicu- 

 lære, lig(4edes siddende paa en lang Stilk (Fig. 26, b). 



This Annelid l)cars great resemblance to M[irio(hde 

 Heeri, Mgrn., though the body is considerably narrower, 

 and the capilliform setæ not, as in that form, finely 

 toothed towards the points. Moreover, Malmgren's drawing 

 of the ungueal setæ in M. Heeri shows no trace of the 

 inspissation at th(> end of the stem distinguished in the 

 uncini of the animal described above; and hence I have 

 established it as a new species of the same genus.

The tulies, '/j""" in thickness, consist of hard mud, 

 studded with minute pebbles and long siliceous needles, 

 apparently sponge-needles (PI. VI, tig. 15). None of the 

 specimens could be got out of the tubes entire; one had 

 a rounded extremity, posterior to wliich were 3 segments 

 with setæ, all capilliform (PI. VI, tig. 13); this was ]i rob- 

 ably the anterior part of the animal, though I failed to 

 find any trace of a buccal aperture. The following seg- 

 ments had all of them ungueal setæ, arranged side by 

 side, 8 or 10 together; the tori are exceedingly long, 

 reaching almost on to the ventral sm-face. The uncini 

 furnished with 2 jags at the point (PI. VI, tig. 14), which 

 is slightly curved, as in J7. Scirsii ; the setæ are not 

 compound. As in J/. Sarsii. each of the longer segments 

 has 2 internal sacs, apjiarently disemboguing lietween the 

 torus and the fascicle of capilliform setæ (Pl. VI. fig. 13, «).

Length a fraction over 3'"' — including the branchiæ

Body round; posterior porticm somewhat depressed, 

 with a; pointed extremity ; anus terminal (PL VII, fig. 23). 

 The ventral furrow can be distinguished only on the 

 posterior portion of the body. The collar curving down- 

 wards in the lateral region; anteriorly and posteriorly 

 with erected lobules, between which are seen compara- 

 tively deep incisions. On the 1st segment none but caj)il- 

 lary setæ; on the succeeding segments also ungueal setæ, 

 ventrally situated. Two kinds of capillary setæ, the 

 one long and slender with a narrow bordered extremity 

 (PI. VII, fig. 25), and the other short, subspatulate, uni- 

 formly broad-bordered, and belted below the short pointed 

 extremity. The ungueal setæ biserial, those in the first
