Drueklaser; stundom er Cellernes ydre Væg sammen- 

 voxet nederst ved Grunden. Polypcellerne ere cylindriske, 

 fuldstændigt retraktile, 5 — Q mm lange, forsynede med 8 stærke 

 Længderibber, imellem hvilke dybe Furer. Polyperne 

 cylindriske, retraktile, 6""" lange, med 8 Bibber, især frem- 

 trædende paa Kroppens forreste Del, hvor der opimod 

 Tentakelskiven er imellem hver to Tentaklers Grund et 

 langagtigt, triangulært Felt, nøgent til Siderne, men i Midten 

 en Spikelrække. Tentaklerne ere 2,5 mra lange, forsynede med 

 Spilder paa den aborale Side; Pinnulerne have ligeledes 

 Spilder. Paa Basaldelen er Dobbeltstjerner almindeligst ; 

 mange af disse ere særegne. Paa Polypcellen ere Spindler, 

 Køller og Klubber hyppigst, paa Polyperne Spindler og 

 Køller. Ooenenchymet rigt paa Spikier. Spindelformen 

 den almindeligste her. Svælgrøret har 8 Rækker Spilder. 

 Farven gul, spillende i det Røde. 



are placed closely together and resemble clusters of grapes; 

 sometimes the outer wall of the cells is concreted together 

 close to the base. The polyp-cells are cylindrical, completely 

 retractile, and 5 — 6 mm in length; they are furnished with 

 8 strong longitudinal ribs with deep furrows between them. 

 The polyps are cylindrical, retractile, and 6 mm in length; 

 they have 8 ribs, and these are specially prominent in the 

 anterior part of the body, where, in proximity to the ten- 

 tacular disk, between the base of every two tentacles, there 

 is an elongate, triangular area, bare at the sides but with 

 a series of spicules in the middle. The tentacles are 2,5 mm 

 in length, and are furnished with spicules on (the aboral 

 side. The pinnules have also spicules. On the basal part, 

 bistellate spicules are the most frequent, many of them 

 being peculiar. On the polyp-cell, fusees, subclavates, and 

 clavates are the most frequent spicular forms ; and on the 

 polyps, fusees and subclavates are the most frequent forms. 

 The sarcosoma in rich in spicules, and the fusiform is, 

 here, the most frequent one. The gullet-tube has 8 series 

 of Spicules. Colour: yellow, shading to red.
