The largest specimen from Stat. 133 has 15 arms 85 mm. long; one of the IIBr series 
is 3 (2 + 3), the other four being 4 (3 + 4); another has 19 arms 70 mm. long; two of the 
IIBr series are 2, one of these bearing internally a lllBr 2 series; a third has 15 arms, there 
being one IIBr series on each ray; the IIBr series are all 4 (3 + 4); the fourth specimen, 
which is small, has i 1 arms. 
One of the examples from Stat. 144 has 18 arms, there being no IIBr series on one 
ray; the other has 17 arms 95 mm. long, and is evidently young. 
The individuals from Stat. 162 are small; one has 14 arms with all the IIBr series
