thick and rough. The polyps are prominent, blunt conical warts with a diameter 

 of 1 to To mm. ; the operculum is conical. The distribution of the verrucse is 

 varied ; they occur all over the twigs and finer branches, only on the short 

 diameter of the flattened branches, and on one surface of the main axis. The 

 spicules of the ccenenchyma are mainly spindles but very irregular ; those 

 aroun(,l the base of the polyps are arranged peripherally usually in two rows, 

 and these are surmounted by groups of three spindles at the base of each 

 tentacle. The " ajolis-like " spindles are 0"6 mm. in length and the spiny discs 

 are 03 mm. x 02 mm. The axis is horny and fibrous varying in colour from 

 black to light brown.

The ccenenchyma is thick and rough ; the polyps are low and ari'anged in 

 close spirals ; the calyces are about 0'8 mm. apart, and 0'8 mm. in diameter by 

 0"J: mm. in height ; they stand perpendicular to the ccenenchyma and have a 

 somewhat elongated oval outline with the long axis parallel to the length of the 

 stem. The mouth is truncated and has eight lobes ; the oral region of the 

 polyp is wholly retractile. The spicules on the surface of the ccenenchyma are 

 broad, warty and club-shaped, or thick, spindle-shaped bodies often almost flat ; 

 those towards the apex are densely covered with rough warts granulated or 

 branched ; they have the following measurements : 0'276 mm. x 0096 mm. ; 

 0-258 mm. x 021 mm. ; 0228 mm. x 0078 mm. ; 022 mm. x 0-108 mm. ; 021 

 mm. X 012 mm. In the deeper layers the spicules are more spindle-shaped 

 and occasionally thicker at one end than the other ; they bear scattered warts 

 which project straight outwards and are terminally expanded or branched : — 

 0-5(3 mm. x 0-08-t mm. ; 0-24 mm. x 0-066 mm. ; 0-18 mm. x 00-42 mm. Rod- 

 like bodies with elongated unbranched warts are 0-8 ram. in length and 0-03 mm. 

 in breadth. The colour is yellowish-white.
