While the number of arms is, evidently, normally 20, one of 
my specimens has only 18, two only 19 arms. The figures 65.a—c 
show the peculiar serration of the pinnules.

pinnules (a—b) and oral pinnule (c); the

which has ca. 30 arms. (The type specimen had 28, the specimen 
lent me by Prof. B e n h a m had probably 38 arms.
