Diagnosis. — Related to Diplasterias, but abactinal surface soft, rather irregularly 

 and finely papillose and the abactinal plates thin (with rudimentary spinelets only), 

 forming an irregular reticulum entirely concealed by the skin; superomarginal plates 

 well developed, bearing one spine wreathed with pedicellariae, and having long descend- 

 ing processes which support a broad, vertical, intermarginal channel; inferomarginals 

 with two webbed spines (each with a cluster of pedicellariae on outer face) or with 

 one spine; no aetinal plates; adambulacral plates regularly diplacanthid; with two 

 contiguous pairs of postoral adambulacral plates; interbrachial septum strongly 

 calcified; gonads opening ventrally, eggs very large; good-sized, broadly lanceolate 

 straight pedicellariae on furrow margin; rays five to eight. 



Koehler, 1923, p. 25, includes two species, the type and C. bradtiata. I am not 

 certain of the status of Diplasterias induta Koehler (1908, p. 575) which is described 

 as being close to turqueti and hence probably a Cryptasterias. But Koehler (1923, 

 p. 27) states that other than branchiata, turqueti is the only known species.
