both in equal proportions. Crinometra in this respect is exactly 
like Pachylometra, its representative in the East Indies. 
All the species placed by Carpenter in his '”Valida” group 
with the single exception of valida itself are in reality synonyms 
of Comatula rotalaria. In number of names this species exceeds 
all other crinoids, there being nearly fifty different names and 
combinations to its credit, or more than one for every two years 
since it was first discovered !

Pelew Islands. One magnificent specimen with about one 
hundred and twenty arms 150 mm. long; cirri XXXV, 30, 40 mm. 
long, large and robust, on a large convex centro-dorsal with a 
deeply concave dorsal pole. 
In general appearance this species is much like C. pinguis 
from Japan, especially in regard to its centro-dorsal and cirri; but 
the constantly fewer arms in the latter and the dorsal processes 
on the cirrus joints are sufficient to distinguish it at once. 
Professor Kæhler has recorded -a specimen of C. robusti- 
pinna. from Amboina, but from his description it seems probable 
that the example really belongs to this species, which has previ- 
ously been found at Amboina, Carpenter's original description 
of robustipinna is perfectly applicable to certain specimens of 
bennetti,
