appeared. They are completely overgrown by a light brown 

 Sympodium-like Alcyonid, which agrees with Kukenthal's 

 account of Alcyonium (Ery thro podium) membranaceum. 

 Owing to the friable nature of the specimens in the dried 

 condition, very little of the internal structure can be dis- 

 tinguished. 



There is considerable variet} 7 in the spicules of the ccenen- 

 chyma. There are (1) approximately spherical bodies 

 087 x -080 mm. ; -120 x -105 mm. ; -122 x -105 mm. ; (2) 

 short, thick cylinders with about two bands of thorny warts 

 087 x -070 mm. ; -105 x -070 mm. ; -122 x -075 mm. ; and 

 (3) irregular bodies and a few crosses -087 x -077 mm.; -105 x 

 087 mm. ; -122 x -122 mm. 



The polyp-spicules are spindles -227 x -070 mm. ; -240 x 

 070 mm. ; -245 x -077 mm.
