OPHIURA CINEREA.

with specks of umber hrown on disk, and bands of the same on arms ; 

 below, nearly white. The iip]wr arm-plates are usually not broken 

 until the animal has a disk at least 12"""'. 



This species differs from others with radial shields and unequal spines, 

 as follows : from (). ruhlvioidd, in position and shape of mouth-shields ; 

 from O. jxinamensis, in having broken upper arm-plates, and in shape 

 of mouth-shields ; from O. squconoxissimay in having upper arm-plates 

 broken, instead of scaly. 



A comparison of the original of Muller & Troschel in the Vienna 

 Museum shows that their specimen is a young one of this species. Dr. 

 Lutkeu's name AntiUarum must therefore be dropped.
