This cushion-like starfish is almost circular in outline when alive, but shows on the 

 oral surface a bright orange-coloured pentagon closely papillated and with the 

 ambulacral grooves running as narrow red lines out to the angles. On the aboral 

 surface there are short red spines on the well-marked lobed areas, while the surface 

 between lias a fine fluffy or velvet-like appearance. The larger specimen measures 

 19 centims. in diameter and 10 centims. in height, and is much less spiny on the 

 aboral surface than the smaller specimen, which is about 14 centims. in diameter and 

 8 centims. in height. The animal when alive has a much more globular form than 

 have preserved specimens.
