Locality. Seychelles Group. Praslin Reef. 2 specimens. 



These specimens agree fairly well with the description of the variety which I described 

 from the Maldives. 



The umbrella of the largest specimen measured 110 mm. when flattened out, and the 

 smaller one measured 80 mm. in diameter. The ex-umbrella is quite smooth, without any 

 trace of a circular band, and without any colouration markings. The margin of the umbrella 

 is too imperfect for counting the number of lobes. The largest specimen has at least 

 18 sense organs, which are very irregular in position. The oral arms are provided with 

 appendages very similar to those described in Maldive specimens. The small appendages 

 adjacent to the oscula are either leaf-shaped or cylindrical. In addition to these appendages 

 there are a few others very much larger. One in the very centre of the oral disc measured 

 22 mm. in length and 7 mm. in width ; others near it are shorter and more cylindrical. 

 Both specimens are thickly covered with Green Cells or Zooxanthellee.
