A MONOGRAPH OF THE EXISTING CRINOIDS 543 



Abnormal specimens. — In view of the constancy of the division series in this 

 species, it seems advisable to call attention to the few deviations which have been 

 recorded. 



In the Siboga specimen from Banda one of the IIIBr series is 1, and two are 2. 



In Duncker's specimen from Ekalin, St. Matthias Island, one of the IIBr series 

 is 2 and bears externally a single IIIBr 2 series. 



In one of Schodo's examples from St. Matthias Island several of the division 

 series are 2. 



In Willey's specimen from the Loyalty Islands the outer IIIBr series are 2, all 

 the other division series being 4 (3 + 4).
