Der er i Stilken to Par Septa, som udmærke si^ 

 fremfor de øvrige baade ved deres Stilling og ved deres 

 Muskelanordning, og som maa betragtes soin Retningssepta, 

 Tab. XXIII. Fig. 4 c; de staa lige overfor hinanden og 

 have deres Længdemuskler placerede paa den udvendige 

 Side af hvert Septuni. saaledes nemlig, at de vende fra 

 hverandre i det interseptale Ruin. Tab. XXIII. Fig. 4 d, 

 imedens de transverselle Muskler ere fæstede til den indre 

 Side og vende mod hverandre i det intraseptale Rum. Tab. 

 XXIII. Fig. 4 e. Paa de øvrige 10 Septapar ere Længde- 

 musklerne fæstede til den indre Side af ethvert Septum. 

 saa at de vende mod hverandre i det intraseptale Rum, 

 Tab. XXIII. Fig. 4/. imedens de transverselle ere bundne 

 til den ydre Side og vende til det interseptale Rum. Hvert 

 Septum har i Midten en Bindevævslamelle, der er en For- 

 længelse af Hudens Bindevæv, Tab. XXII. Fig. 11 i; Tab. 

 XXIII, Fig. 2 h, 3 d. rig som tilligemed sine Muskellag 

 er beklædt med et Endothel. der giver hele Gastrovas- 

 eularhulheden sit Overtræk og bestaar af cilierende Cylin- 

 derceller. Tab. XXII. Fig. 11 le. 



Generationsorganerne ere fæstede til Eanden af de 

 ufuldstændige Septa ved et lost Bindevæv og ere kun lidet 

 udviklede. Hos det eneste Individ, jeg havde. fandtes kun 

 ZEggestokke, der dannede Rør, hvori de lidet udviklede JEg 

 laa parvis. Tab. XXII. Fig. 11 /. Det tør luende, at 

 Kjønnet er særskilt, 



Tentaklerne ere udvendigt beklædte med et Eetoderm, 

 bestaaende af cilierende Cylinderceller, imellem hvilke sees 



en stor Mængde Nematocyster.

Jeg har henført Kodioides pedunculata til Familien 

 Phellidæ, omendskjønt jeg maa erkjende, at der ikke findes 

 en saa udpræget Cuticula, som egentlig adskiller Eamilierne 

 Phellidæ og Sagartidæ fra hinanden. Xnar jeg ei vil 

 danne en ny Familie, som jeg i dette Tilfækle ikke fineler 

 paakrævet, forekommer det mig, at den nærmest maa hen- 

 føres til Phelliderne.

There are two pairs of septa in the stem, which distin- 

 guish themselves from the others both by their position 

 and by their muscular arrangement, and these must be 

 considered to be directive septa (Pl. XXIII. fig. 4 c); they 

 arr placed exactly opposite each other, with their longi- 

 tudinal muscles placed on the outer side of each septum 

 in such a manner, that they face from each other in the 

 interseptal space (Pl. XXIII, fig. 4 d); whilst the trans- 

 versal muscles are secured to the inner surface, and face 

 towards each other in the interseptal space (Pl. XXIII, 

 fig. 4 e). In the other 10 pairs of septa the longitudinal 

 muscles ;\rr secured to the inner side of each septum, so 

 that they face towards each other in the intraseptal space 

 (Pl. XXIII. fig. 4 /), whilst the transversal muscles are 

 attaehed to the outer side and face towards the interseptal 

 space. Each septum has in the middle a eonnective-tissue 

 lamella. which is a prolongation of the integumental con- 

 nective-tissue (Pl. XXII. fig. 11 i; Pl. XXIII, fig. 2 7*. 

 3 d) and which, as well as its musculous laver, is clad 

 with an endothelium that forms the covering of the entire 

 gastro-vascular eavity. and consists of eiliating cylinder-cells 

 (Pl. XXII. fig. 11 le). 



The reproductive organs are attaehed to the margin 

 of the imperfect septa by a loose eonnective-tissue, and are 

 onlv little developed. In the single specimen I had, there 

 were onlv ovaries to be found, which formed tubes in which the 

 but slightly developed ova lav in pairs (Pl. XXII, fig. 1 1 1). 

 It may perhaps be the case that the sexes are separated. 



The tentacles are externally clad with an eetoderm 

 consisting of eiliating cylinder-cells. between which a great 

 multitude of nematocysts are observed. 



Habitat. 



Station No. 35. Onlv one specimen. 



I have assigned Kodioides pedunculata to the family 

 Phellidæ. altough I must aeknowledge. that there is not 

 found sueli a distinguished cuticulum as really divides the 

 families Phellidæ and Sagartidæ from each other. When, 

 therefore. I do not establish a new family. which I do not 

 consider necessary in the present case, it appears to me that 

 it will be most appropriate to assign it to the Phellidæ. 



Generic characteristics. 



The body encrusted, piriform, with a long bare stem 

 terminating in a pedal disc. Two series, containing a few 

 retractile tentacles. 12 pairs of septa. of which 6 pairs

 No gullet-groove. Mesodermal. annular muscles. Acontia.
