A MONOGRAPH OF THE EXISTING CRINOIDS 



103 



Notes.-The preceding description is adapted from the original description by 

 Carpenter, with a few additions from his figures. At the British Museum in 1910 I 

 examined one large and two small specimens from the type material In he largei 

 specimen the cirri are XIV, from 50 to 54 mm. long; the eighth or ninth is a transition 

 segment I noted that this species is remarkable for the great size and stoutness of its 



cirri. 



These specimens were later examined by Prof. Torsten Gislen, who suggested that 

 perhaps there were muscles in the most proximal syzygies.
