Fig. 54. A, B. Camptoplites areolatus (Kluge). St. 175, South Shetland Islands. A. Bifurcation in frontal 

 view. This bifurcation is near the top of the branch. An older one would show more distinct flexible 

 zones or incipient joints. B. Two zooecia and an ovicell. The stalk of the small avicularium is partly 

 indistinguishable though its point of attachment beside the large avicularium is clearly visible The 

 thickened edge of the cryptocyst is outlined. C, D. C. asymmetricus sp.n. C. 87 . 12 . 9 . 188 1 . Challenger 

 St. 320, off Patagonian Shelf. Bifurcation in frontal view. D. St. 156, South Georgia. The stalks of the 

 aviculana are invisible. The second outer distal spine underlies the ovicell. 



In Figs. A and C the zooecia are lettered according to Harmer's scheme and the axillary chamber 

 runners and rootlet are stippled, c. cryptocyst, d.w. distal wall, ect. edge of calcified part of ectooecium' 

 j. joint, l.w. lateral wall, o.a. lateral oval areas, pr. position of projection from basal wall (indicated bv 

 dotted line). J
