be of the irregular, finger-print type (Fig. 50 B), also found in C. retiformis var. tenui- 

 spina, or more regular (Fig. 50 C) as in typical C. retiformis. Although approaching 

 C. retiformis in this way, the variety is distinguished from it, and resembles C. latus, in 

 the shape of the zooecia and of the small avicularia, and in the short stalks of the large 

 avicularia (Fig. 50 A). In the large size and marginal position of the large avicularia, 

 and the broader shape of the ovicells it resembles var. striata, but it differs from it in

 moderately advanced stage in the obliteration of the reticulation. Axillary chamber and runners stippled. 

 Some zooecia have one small avicularium, others two. B. Ovicell from same colony showing an earlier 

 stage of calcification. Slightly oblique view. C. St. 140, South Georgia. Ovicell with more regular

 direction of the spines and the sculpture of the ovicells. 



The ovicells do not appear to be arranged in zones, but, as they were described from 

 a longer branch than the three-zoned branches of var. striata, bearing ovicells through-
