had found, in working over the magnificent collection of comatulids made at Singapore 

 by Svend Gad, that the common Zygometra occurring there and hi the Mergui Archi- 

 pelago is not the same as that called elegans by Bell, though it had been united with 

 that species by Carpenter. I gave a few of the characters of the new species and 

 said that a satisfactory description could be found in my report upon the comatulids 

 of the Copenhagen Museum. 



In 1912 I recorded and gave notes upon a specimen of Zygometra comata from 

 Hongkong that I had examined in the Hamburg Museum in 1910. In my monograph 

 on the crinoids of the Indian Ocean published later in the same year I gave the 

 synonymy of Z. comata and its geographical and bathymetrical ranges. 



In 1913 I recorded and published notes upon two specimens that had been col- 

 lected by Captain Suensson, commanding one of the Danish cable repair ships, off 

 Hongkong. 



The specimen in the British Museum recorded by me from Holothuria Bank in 

 1913 under the name of Zygometra punctata is probably an example of this species. 

 This is inferred from the notes given on the cirri. The specimen has not been 

 reexamined. 



In a memoir on the comatulids collected by the Australian Fisheries Investiga- 

 tions steamer Endeavour between Fremantle and Geraldton, Western Australia, 

 published in 1914, I discussed the relationships between Z. comata and the other 

 species of the genus. 



In the Siboga report upon the unstalked crinoids published in 1918, I recorded 

 and described four specimens from three Siboga stations, and in 1929 I recorded two 

 specimens from the collections made by the Eastern and Associated Telegraph Co.'s 

 cable repair ship Patrol, and another from Singapore. 



In 1934 Dr. Th. Mortensen listed Z. comata as one of the crinoids occurring at 

 Hongkong. 



In 1936 Dr. Torsten Gisl6n recorded and gave notes upon a specimen collected 

 by Dr. C. Dawydoff at Pulo Condor, Cochinchina. 



In 1938 Dr. H. L. Clark recorded and gave extensive notes on 37 specimens from 

 Roebuck Bay and vicinity and 2 from the vicinity of Lagrange Bay collected by him- 

 self in 1929 and 1932.
