 XIV. Fig. 8/. Æg i deres tidlige Udvikling udfylde enkelte 

 Æggestokke, imedens andre synes at være tomme. Svælg- 

 røret er cylindrisk, Tab. XIV. Fig. 8 g, temmelig langt, 

 har paa hver Side at' Svælggruberne flere Længdefolder og

Station 260—261. To Exemplarer. 



Artskarakter. 



Fodskiven rund, membranagtig udbredt, omtrent 8""" i 

 Tversnit, med en tynd Rand. Underfladen plan, fint foldet. 

 Kolumnen omtrent 10""" hoi, cylindrisk; dens to nederste 

 Trediedele forsynede med en tynd, inkrusteret Skede. der 

 har en fri, afrundet Rand foroven ; den øverste Trediedel 

 Qøgen med Længdefolder, hvorpaa store Sugevorter, staa- 

 ende i Længderækker. Indenfor Skeden lignende Længde- 

 folder med Sugevorter. Mundskiven lidt hvælvet, fint foldet. 

 Mumien aflang med tykke, foldede Læber og vide Mund- 

 vige. Tentaklerne retraktile. koniske, korte og tykke, i 3 

 Rækker. I den Iste og 2den Række 12 i liver: i den 3die 

 (vderste) 24; disse ere de mindste. Hele den ovre. nøgne 

 Del med Mundskiven og Tentaklerne kan indtrækkes i 

 Skeden. der lukker sig. Farven: Skeden graabrun; den 

 nøgne Del af Kolumnen rosenrød. Mundskiven brunrød 

 med lysere Striber. De indre Tentakler intens brunrøde, 

 især langs den aborale Side; de i 2de»i og 3<\\e Række 

 noget lysere. 



Phellia violacea. n. sp. 



Tab. IV, Fig-. 7; Tab. XIII. Fig. 10; Tab. XIV. Fig. 9, 10. 



Phellia violacea er omtrent 25""" hoi. medens Mund- 

 og Fodskive ere mindst 10""" bredere. Fodskiven er 35""" 

 bred og ruml med en tyk. jævn, ringformig Rand, der 

 danner ligesom en Vold omkring den nederste Del af 

 Kolumnen. Tab. IV, Fig. 7 a. Fodskivens Underflade 

 er konkav, straaleformigt foldet fra Centrum mod Peri- 

 pherien. 



Kroppen er cylindrisk, smalere nedad mod Fodskiven, 

 bredere foroven, Tab. IV, Fig. 7. Dens nederste tre Fjerde- 

 dele, ligesom Fodskivens Rand. er beklædt med en membranøs 



abundance. A few septa carry 2 — 3 acontia, others only 

 one (Pl. 8 e). and below the acontia. down towards the 

 bottom of the gastral cavity, lie the reproductive organs. 

 which are not much developed (Pl. XIV, fig. 8 J). Ova 

 in their earliest development occupy some ovaries whilst 

 others ap})ear to be empty. The æsophagus is cylindric 

 (Pl. XIV. fig. 8 g) rather long, and has several longitud- 

 inal folds on each side of the gonidial-grooves. It is fur- 

 nished with both transversal and longitudinal muscles. 

 The parieto-basilar muscle is thin but broad, and extends 

 itself a considerable way both upwards and downwards.

 Station No. 260 — 261. Two specimens. 



Speciflc characterieticB. 



The pedal disc ronnd, membranaceously expanded, 

 measures about 8""" in breadth, has a free margin. The 

 under surface plane, finely folded. The column about 10""" 

 in heiglit, cylindric. its lowest two tliirds part furnished 

 with a thin encrusted sheath having a free. rounded margin 

 at the top. Tlie uppermost third purt bare, with longitud- 

 inal folds upon which are large suckers placed in longitudinal 

 series. Inside of the sheath similar longitudinal folds with 

 suckers. The oral disc shghtly arcuate, finely folded. The 

 mouth olilong. with thick, folded labiæ and wide oral 

 angles. The tentacles retractile, conical, short and thick. 

 placed in 3 series. In the first and second series 12 ten- 

 tacles in each: in the third series (outermost) 24 tentacles, 

 and these last are the smallest in size. The entire upper 

 bare part with the oral disc and the tentacles. can 

 be withdrawn into the sheath. which then closes itself. 

 The colour. The sheath grey-brown ; the bare part of the 

 column [rose-red. The oral disc brown-red with lighter 

 coloured stripes. The inner tentacles intense brown-red, 

 especially along 'the aboral side; those in the second and 

 third series somewhat Lighter in colour.

Phellia violacea is about 25""" in height, whilst the 

 oral and pedal discs are at least 10""" broader. The pedal 

 disc is 35™"' broad. and round, with a thick, even, annular 

 margin which forms, as it were. a ridge round the lowest 

 part of the column (Pl. IV, fig. 7 a). The under surface 

 of the pedal disc is concave. and folded radiately from the 

 column towards the periphery. 



The body is cylindric. narrowest downwards towards 

 the pedal disc. and broadest at the top (Pl. IV. fig. 7).
