148 ECHINODERMA OF THE INDIAN MUSBXTM, PART Vn. 



Antedon moorei (p. 287) is apparently the same thing as this, but is a young speci- 

 men ; the spines on the cirrus segments are a trifle more conspicuous , and the 

 animal is all around more slender, as would be expected. In the type of ■limllis 

 the cirrus segments are never quite so long as broad, the earlier being longer 

 than broad in moorei, probably due to the undeveloped condition of the latter.
