The general cceueucliyma of the stem and branches is thin and transparent, 

 and shows a layer of fiat scale-like spicules, longer than })road, arranged with their 

 long axis parallel to the length of the branch. 



The polyps are arranged in whorls of two or three, and may also occur singly 

 between the whorls, l)ut in no case are there more than three in a whorl. They 

 are long and slightly club-shaped, and their apices are always turned in towards 

 the stem or branch on which they stand. The polyp spicules are tlat, irregular 

 scales with many warty tuliercles, and some of them have one of their edges toothed. 

 They are arranged in nine transverse and four longitudinal rows. There are two 

 rows on the abaxial surface and two, not so complete, on the lateral surfaces ; the 

 axial surface is free from spicules. The spicules of the first three transverse 

 abaxial rows have spines on their free edges, and the same is true of those on the 

 first two lateral rows on each side. The operculum forms a distiuct sharj) cone, and 

 consists of eight slightly curved spear-shaped spicules. 



The spicules of the general cwnenchyma, which form a complete covering for 

 the stem and branches, are long narrow flattish scales with the nucleus eccentric. 

 Their measurements, length and breadth in millimetres, are : 



0-85xO-175; O'SxO-l; 07x0-l7; 0-6x0-2; 0-GxO-l; 0-25x0-07. 



The polyp sjoicules are broader than the above and more like fish scales. 

 Their measurements, maximum length and breadth in millimetres, are : 

 0-4x0-2; 0-35x0-2; 0-3x0-25; 0-275x0-l75. 



The spicules of the abaxial and lateral rows, which have spines on tiieir free 

 edges, have the following dimensions : — 0'37 x 0'3 ; 0"33 x 0'3 ; 0'3 x 0"3. The spear- 

 shaped opercular spicules average 0'6 mm. in length and 0"27 mm. in maximum 

 width.
