Denne Annelide har stor Lighed med Myriochele Heeri, 

 Mgrn. ; den ei- dog betydeligt tyndere end denne og har 

 ei som denne tine Tagger henimod Spidsen af Haarbørsterne. 

 Malmgrens Tegning af Hageborsterne mangler ogsaa den 

 Fortykkelse i Enden af Stilken, der bærer den orre Ende, 

 som tindes hos det ovenfor beskrevne Dyrs Hageborster. 

 Jeg har derfor troet at burde opfore den 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. Yl, 

 Fig. lo). Intet Dyr kunde faaes helt ad; paa et saaes 

 en afrundet Ende og bag denne 3 Segmenter med Kapil- 

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

 været en Forende, skont Mundens Beliggenhed ei kunde 

 opdages. Paa alle de følgende Led ogsaa Hageborster, 

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

 og naa næsten sammen paa Bugfladen. Hageborsterne 

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

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

 ikke sammensatte som hos denne. Ligesom hos M. Sarsii 

 tindes der i hvert af de hengere Segmenter to Sække, der 

 synes at udmunde mellem Torus og Kapillærborstebundtet 

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

Legemet rundt, Bagkroppen lidt fladtrykt, ender 

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

 synlig paa Bagkroppen. Kraven nedboiet i hele Sidepartiet 

 med fortil og bagtil opretstaaende Flige, mellem hvilke der 

 tindes temmelig dybe Indsnit. Paa Iste Segment kun 

 kapillære Børster, paa de 7 følgende ogsaa Hagebørster 

 ventralt stillede. De kapillære Børster 2 Slags: lange, 

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

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

 bræmmede nedenfor den korte Spids. Hageborsterne bise- 

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

 krummet Stilk (T. VII, Fig. 26, a) anden Rad avicu- 

 lære, ligeledes siddende paa en lang Stilk (Fig. 26, b). 



This Annelid bears great resemblance to Myriochele 

 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 21. Heeri shows no trace of the 

 inspissation at the 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 tubes, l j 2 ""' 1 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 which were 3 segments 

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

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

 tind 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 surface. The uncini 

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

 is slightly curved, as in 31. Sarsii: the setæ are not 

 compound. As in 31. Sarsii. each of the longer segments 

 has 2 internal sacs, apparently disemboguing between the 

 torus and the fascicle of capilliform setæ (Pl. VI, tig. 1 3, ft).

Body round; posterior portion somewhat depressed, 

 with a- pointed extremity; anus terminal (PI. VII. tig. 23). 

 The ventral furrow can lie 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 capil- 

 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 

 (Pl. 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
