I have only seen a number of small colonies fixed to algae. 

 The zooecia are arranged in 2 — 9 longitudinal series and are provided 

 with 1 — 5 spines on each side. They belong to the varieties fruticosa 

 and qvadridentata.

Of this species I have only seen the remnants of 5 small colonies 

 each consisting of 1 — 5 pairs of zooecia fixed to cirri of Antedon 

 prolixa.

 (PI. XIX, fig. 1). 

 In the colonies examined the distal wall is (besides the large 

 somewhat semilunaire or angularly bent collection of uniporous 

 rosette-plates found in almost all the members of this family) pro- 

 vided with one, two or rarely three rounded, but otherwise differ- 

 ently shaped pore-chambers of rather diff"erent size. Each of them 

 is provided with a single uniporous rosette-plate, rarely with a few^ 

 As a rule they are present in all the zooecia. I have not seen such 

 pore-ehambers in colonies from Denmark or from West-Greenland, 

 but I have found similar structures in Mcnipea roborata Hincks and 

 Men. ligulata M'Gill.i
