BEANIA 4, 9 



Description. Zooecia erect, straight-sided, tapering towards proximal end (Fig. 35 D). 



Connecting tubes four, arising very close together at proximal end. 



Avicularia stalked, attached to distal border, between the two outer spines on each 

 side, sometimes absent. 



Spines all distal, prong-like, six on aviculiferous zooecia, the outer spine on each side 

 bending over opesia, seven on zooecium without avicularia (Fig. 35 C), all directed 

 distally. 



Ovicells unknown. 



Remarks. Only three zooecia of this species of Beania have been found but they are 

 so unlike those of any known species that I can only regard them as new in spite of 

 the undesirability of describing species from scanty material. 



B. scotti differs from B. erecta in the shape of the zooecia, the number and length of 

 the distal prongs, and the shape and position of the avicularia. It appears also to differ 

 in having four connecting tubes instead of six, though this point cannot be settled with 

 certainty from this material as the tubes are not mounted in a convenient position. 



A structure which appears to be the stump of a rootlet arises very near the proximal 

 connecting tube in the zooecium shown in Fig. 35 D.

Station distribution. Not represented in the Discovery collections. 



Geographical distribution. Tasmania (Hincks); Victoria (MacGillivray); New Zealand 

 (Waters; Terra Nova); Chatham Island (Waters); Indian Ocean (Thornely); Red Sea (Waters); 

 Suez Canal (Hastings); Cape Verde Islands (Kluge); Tortugas (Osburn); St Helena (Marcus); 

 Gorgona (Hastings). 



The Discovery specimen agrees very closely with Beania intermedia (Hincks). Hincks 

 described one pair of marginal spines. My New Zealand specimens have one to three 

 marginal spines on each side, in addition to a spine near the avicularium (Fig. 36 B). 

 This short spine, just distal to the attachment of the avicularium, is rather constantly 

 present in the New Zealand specimens and is shown in Hincks's and Waters 's figures, 

 where it appears to be the only spine in addition to the two or three distal ones. It is 

 not shown in MacGillivray 's figure in which there is a marginal spine on one or both 

 sides proximal to the avicularium. 



The specimens from the Red Sea (15. 10.20.4), Suez Canal (26.9.6. 134c, d) and 

 Gorgona (29.4.26.248) differ from these typical specimens in their rather larger 

 zooecia and in the complete absence of marginal spines. The avicularia, particularly of
