The tentacles, a somewhat darker rose-red than the oral disc. 



noget mørkere rosenrød end Mundskiven. 



Findested. 



Station 35. 3 Exemplarer. 



53. 2 voxne og 3—4 ganske smaa Exem- 

 plarer. 

 — 353. 1 voxent og nogle mindre, 



alle siddende paa Stilker af Bathycrinus Carpenteri. 



Slægtskarakter. 



Fodskiven lancetformig udvidet, omklamrende saagodt- 

 som ganske et tyndt, cylindrisk, fremmed Legeme (Stilken 

 af Bathycrinus Carp.). Kroppen aflang, tærkt ribbet og 

 forsynet med hule Papiller. Mundskiven blottet. Mange 

 fuldstændige Septa; mesodermale Cirkukermuskler. Tentak- 

 lerne faa, siddende i flere Rækker. 



Artskarakter. 



Den aflange Podskive. der omklamrer Stilken af Ba- 

 thycrinus Carpenteri, er indtil 25""" lang og 5"'"' bred. 

 Kroppen (Kolumnen) er næsten ovoidformet. fast, næsten 

 bruskagtig at fole paa, omtr. 10""" hoi; dens øverste Rand 

 10""" lang, 7""" bred; dens nederste Del er glat, dens øver- 

 ste er forsynet med 24 stærke Ribber, som have eftér 

 Længden stillede smaa Papiller, paa hvis afrundede Endr 

 en tin Aabning. Mundskiven hvælvét med 24 Folder, ud- 

 straalende fra Mumien mod Kropsranden, og paa hvilke 

 sees enkeltvis lignende Papiller som paa Kroppen. Mund- 

 aabningen aflang, 2 Rækker Tentakler, 24 i hver; tie indre 

 lidt større, end de i ydre Ra^kke. Farven: Foden og 

 Kroppen bleg rosenrød, næsten hvid med stærk Perlemors- 

 glands. Mundskiven mørkere rosenrød. Tentaklerne noget

Fodskiven er rund. omtrent 80 mBI bred, noget videre 

 end Kolumnen med en tyk, undulerende Raml. Underfla- 

 den, som er lidt nedsænket, er foldet fra Centrum mod 

 Peripherien. Folderne blive tykkere mod Randen, og imel- 

 lem dem sees en fin Fure, der angiver Insertionerne af 

 Septa. Fodskiven fæster sig stærkt til Stene ; den er meget

Habitat. 



Station No. 35. Three specimens. 



— „ 53. Two adult, and 3 — 4 quite small 

 specimens. 

 „ 353. One adult, and a few small speci- 

 mens. 

 All seated on the stems of Bathycrinus Carpenteri. 



Generic characteristies. 



The pedal disc is lanceolately expanded, embraces, 

 nearly completely, a thin, cylindrical, foreign body (the 

 stem of Bathycrinus Carp.). The body oblong, strongly 

 ribbed. and furnished with hollow papillæ. The oral disc 

 exposed. Many perfect septa. Mesodermal circular muscles. 

 Few tentacles, placed in several series. 



Speciflc characteristies. 



The oblong pedal disc, whieh embraces the stem of 

 Bathycrinus Carpenteri. measures up to 25""" in length aud 

 5""" in breadth. The body (the column) is almost oviform, 

 firm, feels almost cartilaginous to the touch, measures 

 about KJ""" in height. Its upperinost margin is 10"'" in 

 length, and 7'""' in breadth. Its inferior portion is smooth. 

 Its uppermost part is furnished with 24 strong ribs hav- 

 ing papillæ placed longitudinally on thein. and these have 

 a minute opening in their rounded extremities. The oral 

 disc arcuate, with 24 folds radiating from the mouth 

 towards the body-margin, upon whieh a few papillæ similar 

 to those of the body are seen. The oral aperture oblong. 

 Two series of tentacles — 24 in each; those of the 

 inner series being a little larger than those of the miter 

 series. Cohur. The base and body, pale rose-red. almost 

 white, with strong mother-of-pearl lustre. The oral disc, 

 a darker rose-red. The tentacles, somewhat darker rose- 

 red than the oral disc.

The pedal disc is round, about 80""" in breadth, 

 somewhat wider than the column. and has a thick undulating 

 margin. The under surface, whieh is somewhat depressed, 

 is folded from the centre towards the peripherv. The folds 

 become thicker towards the margin, and between them a 

 slender groove is seen. whieh indicates the insertions of
