tliem sometimes forked. The small spicula of the coenenchyma are of 

 various forms of small, very roughly warted spindles, heads, double- 

 heads, double-stars, crosses, and various irregular and compound forms. 

 The polyp-spindles are slightly and distantly warted, quite slender 

 and acute ; most of them are straight and pretty regular ; some are 

 much curved and very acute at both ends ; others are slender club- 

 shaped, more strongly warted at the larger end.

In the largest specimens the trunk divides irregularly, close to the
