A MONOGRAPH OF THE EXISTING CRINOIDS 355 



Speaking of the specimens from Macclesfield Bank, Annam, Cochinchina, and 

 Cambodia, Gisl<Sn said that the cirri in the young are about XV, 26-29, and in the 

 large specimens about XXV, 29-36. The dorsal spines are prominent and pointed. 

 The synarthrial tubercles are well developed. The two specimens from the Maccles- 

 field Bank and Annam are not quite so typical as those from Cochinchina and 

 Cambodia. 



In 1909 I wrote that Amphimetra molleri is altogether a more delicate species 

 than A. milberti, the only other species of the genus Amphimetra with very short 

 subequal cirrus segments, and is very readily distinguished by having practically all 

 the cirrus segments, instead of only the outer ones, furnished with dorsal spines. 

 The species here referred to as A. milberti is in reality A. spectabilis, of which two speci- 

 mens had recently been received from the Albatross, which at that time was working 

 among the Philippine Islands. 



Abnormal specimen. — Chadwick noted that in one of the arms of one of the two 

 specimens from Ceylon Pearl Oyster Fisheries station LVII, which was unfortunately 

 detached when found, the fifth brachial beyond the third syzygial pair is an axillary, 

 and in each of the two arms following this axillary the third and fourth brachials are 

 united by syzygy.
