Drueklaser: stundom er Cellernes ydre Væg sammen- 

 voxet nederst ved Grunden. Polypeellerne ere eylindriske, 

 fuldstændigt retraktile, 5 — 6""" lange, forsynede med 8 stærke 

 Længderibber, imellem hvilke dybe Furer. Polyperne 

 eylindriske, retraktile, 6""" lange, med 8 Ribber, især frem- 

 trædende paa Kroppens forreste Del. hvor der opimod 

 Tentakelskiven er imellem hver to Tentaklers G-rund et 

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

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

 Spilder paa den aborale Side; Pinnulerne have ligeledes 

 Spikler. Paa Basaldelen er Dobbeltstjerner almindeligst; 

 mange af disse ere særegne. Paa Polvpcellen ere Spindler, 

 Koller og Klubber hyppigst, paa Polyperne Spindler og 

 Koller. Coenenchymet rigt paa Spikler. Spindelformen 

 den almindeligste her. Svælgroret har 8 Rækker Spikler. 

 Farven gul, spillende i det Rode. 



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'"'" in length ; they are furnished with 

 8 strong longitudinal ribs with deep furrows between them. 

 The polyps are cylindrical, retractile. and 6""" 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""" 

 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 sarcosonia 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 i-ed.
