Plate 23, Fig. 3 



Trophosome. — Colony, 20 mm, consists of a fascicled, unbranched 

 stem, and hydrothecae with long pedicels. There are not many tubes in 

 the fascicle ; each one, instead of ending abruptly, passes out to form the 

 pedicel of a hydrotheca, the terminal one being much longer than the 

 others, the free portion 3.5 mm in length; the pedicels of the others, al- 

 though not so long, are still of considerable length, up to 2 mm. Each 

 pedicel has 2-3 annulations at the base of the hydrotheca ; those that ter- 

 minate the tubes of the fascicle have no other annulations ; those that do 

 not have 1-3 annulations at the base. The hydrothecae are large, 1.0 x 0.5 

 mm, not far from being cylindrical except for the rounding of the base. 

 The margin is provided with 10 emarginate, deeply-cut teeth. 



Gonosome. — Gonangia grow from the tubes of the fascicled stem, 

 much similar in shape and size to those of C. flexuosa Hincks (2.0 x 0.5 

 mm), nearly cylindrical, tapering to the base, and truncate distally, the 

 walls slightly wavy, or sometimes definitely corrugated.
