ACTINIARIA 



In the column of all species I have found also smaller nematocysts, 7 12 X 1,5 fi. The nematocysts 

 of the column are sparse, especially the smaller ones. Scattered spirocysts are also observed in the column. 

 In the tentacles I have sometimes observed smaller nematocysts of about the same size as those of U. felina 

 crassicornis.

Colour: Column uniformly red or else with a ground colour of pale red or yellowish, upon which 

 were closely set, irregular blotches and streaks of carmine, so that the general effect was that of a brilliant 

 carmine. Tentacles of a beautiful translucent pink, sometimes uniform throughout, in other cases deepening 

 somewhat in tone at the tips and also at about the middle, where an indistinct band occurred. At the base 

 each tentacle was surrounded by a pair of deeper pink streaks, which were prolonged some distance upon 

 the disc. Oral disc pink in colour, peristome dotted and streaked with crimson, gonidial angles flesh-coloured 

 (Me. Murrich). Column red, oral disc pale, tentacles chestnut-brown with pale apex. Column orange-red 

 (spec, from Recherche bay). Pale red or reddish yellow (Romer & Schaudinn St. 46). 



Dimensions: The largest examined specimens (from the Kara Sea) was about 3,5 cm high and 

 8 cm broad at the base.
