In 1840 Agassiz was not aware of the existence of Brandt's Prodromus 

 where the genus Colobocentrotus was established.

Loven in his Echin. of Lin. says that the type of Linnjeus was collected at 

 Mauritius, or rather that the original of the figure in the French edition of 

 Klein to which Linnteus refers in his twelfth edition came from Mauritius. 

 Leske's figure, to which Blainville and others refer as the typical atratus, has 

 the longer marginal spines rounded at the tip. Blainville further states that it 

 is "d'un blanc violet presque noir," which agrees with the coloring of the spe- 

 cimens from the Hawaiian Islands and Mauritius in the Museum collections.

Mauritius, Seychelles, Zanzibar, M. C. Z. collections. This species has also 

 been noted as occurring at Java and the Moluccas. * 



Mobius has given an excellent figure of Podcqjhora atrata from Mauritius, 

 the dark violet species with long spines rounded at the tip. Echinometra 

 Quoyi Blainv. is only the young of F. atrata. Colob. Leskei Br. is probably 

 P. atrata.

The excellent description of Blainville, with his statement " couleur gen6- 

 rale d'un vert bleuatre, les mammelons verts, les epines livides," leaves no 

 doubt of its identity with the greenish-olive specimens collected at Fakarava
