Type : Lutken's List, Godeffroy Museum, at Hamburg, p. 34. 



Distribution : Littoral in the East Indies ; Mergui Archipel- 

 ago (Carpenter) ; Indian Archipelago (Hartlaub) ; Amboina, 

 Thursday Island (Doderlein) ; Blanche Bay, New Britain (Bell) ; 

 Ceylon (Chadwick) and other localities. 



Material examined: One specimen, taken on coral reef, Te- 

 mukus Roads, Bali, Dutch East Indies, October 25, 1931, by the 

 "Alva." 



Colour: This gloriously coloured shallow- water species has 

 an extensive range of colour variation, described in detail by Dr. 

 A. H. Clark. In some specimens deep purple is the dominant tone 

 with white, cream and yellowish markings ; in others bright green ; 

 in another bright green, variegated with brown and white ; a third 

 type is black and white ; a fourth is dominated by light yellow and 

 orange with variegations, while yet another is deep blood-red with 

 lighter shadings ; a sixth form had chocolate with white markings. 

 Several other types of variations of these primary colours in pat- 

 terns of exquisite variegations have been recorded. 



Remarks : The single specimen taken by the "Alva" is shown 

 in plate 37. Though imperfect, it conforms in the essential diag- 

 nostic characters of the species, as described and figured by Dr. 

 Austin H. Clark (1915, 1921, 1931), who has given an exhaustive 

 analysis of the species, including a complete lucid resume of the 

 early history of this crinoid.
