PART 5 A MONOGRAPH OF THE EXISTING CRINOIDS 299 



In 1910 I recorded a number of specimens in the Paris Museum from various sta- 

 tions of the Mission scientifique du Cap Horn in 1882-1883, giving notes upon them, and 

 reducing rhomboidea to the synonymy of magellanica; by an error Antedon australis (a 

 synonym of Solanometra antarctica) was said also to be a synonym of magellanica. In 

 1912 I mentioned Dr. Rehberg's example, saying that it resembled others at hand from 

 the vicinity of Cape Horn, those referred to being the ones from Mission scientifique 

 du Cap Horn station 100 in the collection of the U.S. National Museum; and I also 

 listed the specimen recorded by Professor Ludwig, which had been collected by Captain 

 Paessler of the Kosmos Line. The latter I had seen in Hamburg, and the former had 

 been sent to me for more detailed study. In 1913 I recorded a specimen from Tom 

 Bay, and another from near Cape Providence where it had been collected by the Sylvia, 

 both in the British Museum, giving notes on them and at the same tune reaffirming the 

 identity of rhomboidea with magellanica. 



A summary of our knowledge of this species was published in 1915, and in 1918 I 

 stated that magellanica was confined to southern South America, the records from the 

 western coast of Central America having reference to a different species.
