fandt jeg ikke uden paa MundsMven Ganglier. Paa Mund- 

 skiveii er der antagelig 12 Gangliegrupper, 6 store og 6 

 smaa, som synes at være forbundne med hverandre med 

 Udløbere, eller rettere med Nervefletninger, udgaaende fra 

 den ene Gruppe til den anden, og fra disse Grupper have 

 da hele den øvrige Nerveudbredning sit Udspring. Naar 

 jeg har benyttet Ordet „antagelig" eller „synes", er det, 

 fordi jeg paa Grand af manglende Material ikke vovede 

 at udtrvkke mig med større Bestemthed.

Et Exemplar. 



Et voxent og •'» smaa Exemplarer. 



Slægtskarakter. 



Legemet langstrakt, cylindrisk, endende tapformigt 

 med en rund Caudalaabning og forsynet med en tynd, 

 inkrusteret Skede. En Tentakelrække. 6 Par fuldstæn- 

 dige Septa, bærende Mesenterialfilamenter og Generations- 

 organer. Udprægede éndodermale Oirkulærmuskler. Svælg- 

 roret delt efter Lamgden. 



Artskarakter. 



Legemet langstrakt, cylindrisk. 70""" langt. 12™ bredt; 

 den forreste Del ender tapformigt med en rund Aabning. 

 Størstedelen ai Kolumnen omgiven af en tynd. inkrusteret 

 Skede. kun dens øverste Del er nogen og forsynet med 

 12 Længdefurer, imellem hvilke brede Længdefelter med 

 spredte Suge vorter. Mundskiven hvælvet og har 12 Folder, 

 straalende ud fra den aflange Mund mod Peripherien. 12 

 lange, retraktile Tentakler i en Række. Kroppens øverste, 

 nogne Del med Mundskive og Tentakler kan indtrækkes 

 i Skeden. Farven: Skeden graagrøn. Kolumnen bleg 

 rosenrød, i dens bagerste Ende spillende lidt i det Violette. 

 Længdefurerne lidt mørkere end Mellempartierne. Mund- 

 skiven har Kroppens Farve. Tentaklerne næstén mørke- 

 røde, spillende i det Karmosinrøde. 



Jeg har fundet det nødvendigt at danne en ny Slægt 

 for det ovenfor beskrevne Dyr, omendskjont det har adskil-

tion before mentioned, which it is certain distributes itself 

 over the entire body of the animal, as. in all the trans- 

 versal sections I took from the different part.; of the body, 

 there always appeared, between the ectoderm and the con- 

 nective-tissue uniting with it, a narrow, finely granulated 

 belt. which could searcely be anything else than trans- 

 sected nerve-fibrils ; on the other hand I found no ganglia 

 except on the oral disc. On the oral disc there are, pre- 

 sumably. 12 ganglial groups, ti large and 6 small ones, 

 which appear to be conneeted with each other by prolonga- 

 tions, or, more correctly, by nervous pleats issuing from 

 the one group to the other. and in those groups the 

 whole of the remaining nervous distribution takes its origin. 

 That I make use of the words ,.presumably" and „ap- 

 pears", is caused by the fact, that I dared not. in the 

 absence of suffibient material, express myself more deci- 

 sively.

Habitat. 



One specimen. 



i me adult and three small spec- 



imens. 



Generic characteristics. 



The bodj elongate, cylindrical, terminating conically 

 in a round caudal aperture, and furnished with a thin 

 encrusted sheath. One tentacular series. Six pairs of 

 perfect septa, carrying mesenterial filaments and repro- 

 ductive organs. Distinct endodermal circular muscles. The 

 gullet-tube divided longitudinally. 



Speeific characteristics. 



Thf body elongate, cylindrical. measures 70 ram in 

 length. and 12""" in breadth in the anterior part. termin- 

 ates conically with a round aperture. The greater part 

 of the column surrounded by a thin encrusted sheath. only 

 its uppermost part is bare and furnished with 12 longi- 

 tudinal furrows, between which there are broad longitudinal 

 areas with scattered suckers. Tlie oral disc arcuated, lias 

 12 folds radiating from the oblong mouth towards the 

 periphery. Twelve long, retractile tentacles in one series. 

 The superior, bare portion of the body with oral disc and 

 tentacles may be retractéd into the sheath. The colour. 

 The sheath grey-greenish. The column pale rosy-red at 

 the posterior extremity, with a violet play of colour. The 

 longitudinal furrows a little darker than the intermediate 

 areas. The oral disc has the same colour as the body. 

 The tentacles are almost dark-red with a crimson red play 

 of colour. 



I have found it necessary to form a new genus for 

 the above-described animal, although it has several features 

 in common with the genus ,Halcampa", established by
