418 DISCOVERY REPORTS 



The zooecia are rather larger and usually more hump-backed than those of the typical 

 form. 



The difference in the position of the avicularia is not always as marked as in the 

 figured specimens. In shape, too, the avicularia of both the species and the variety are 

 somewhat variable, and the distinction that appears in the figures is much less marked 

 in other specimens.

Fig. 35. A. Beania erecta Waters. St. 160, Shag Rocks. Fertile zooecium. The proximal connecting tube 

 appears to have regenerated. B. B. erecta var. livingstotiei var.n. St. 159, South Georgia. Distal end 

 of fertile zooecium. C, D. B. scotti sp.n. St. TN 194, off Oates Land. In Fig. C the operculum was 

 open and the remains of the tentacle-sheath everted, but these parts have been omitted from the 

 drawing for clarity. The frontal membrane of this zooecium has sagged in preservation. E. B. erecta var. 

 livingstotiei var.n. St. 159, South Georgia. Avicularium. F. B. erecta Waters. St. 160, Shag Rocks. 

 Avicularium. G. B. magellanica (Busk). St. 1564, Prince Edward Island. Avicularium. 

 av.s. avicularian stalk, /.w. frontal membrane, op. operculum, o. ovicell, r. supposed rootlet, r.p. rootlet- 

 pore. The connecting tubes are numbered thus : in B. erecta (with 6), 1 distal, 2-5 lateral, 6 proximal ; 

 in B. scotti (with 4), 1 distal, 2-3 lateral, 4 proximal.
