The individual calyces are low domes when the polyps are retracted and truncated

 than on the front of the colony. A typical calyx measures .6 mm. in height and 1.1 mm. in 

 diameter. 1 h< • calyx walls, as well as the general ccenenchyma, are packed with foliaceous 

 clubs or Blattkeulen which appear when in situ and viewed under a low magnification as 

 rounded bodies or nodules, because they are thus seen "end on", in the calyx walls. the 

 nds being directed upward and ontward. The polyps are heavily spiculated, with a 

 strong collaret of bent tuberculate spicules. Above these each tentacle base is provided with 

 two spicules whose ends meet at a wide angle forming an upward directed point. The dorsal 

 surfaces of the tentacles are covered with longitudinal tuberculate spindles. 



Spicules. The surface of the ccenenchyma is packed with vertically placed typical 

 blattkeulen with their foliaceous ends directed outward. These spicules are verv characteristic 

 of the genus Wrightella, consisting of a basal, irregular, often much branched and tuberculate 

 portion, and a distal part composed of foliaceous expansions gathered together into a globular 

 "head" resembling the bud of a tulip <>r rosé and forming what appears to be a rounded 

 nodule when the spicules are viewed in situ under low magnification. Other blattkeulen are 

 seen with wide foliaceous expansions which are flattened and longitudinally shattered or split. 

 These are often seen in the distal parts of the calyx walls. Curved, tuberculate spindles are 

 found in the polyps and tentacles. 



Co lor. The colony is almost a brick red, or light scarlet. The polyps are yellow and 

 the axis deep crimson. 



General distribution. The type locality seems to be the coast of Mauritius (Ellis 

 and Solander). It has also been reported from the Seychelles, 4 — 12 fathoms (Gray) \ from 

 the Indian Ocean, Farquaar Atoll, Prashu, Seychelles (Thomson and Mackinnon), and from 

 the Cape of I ri lod I lope Ridley).
