Geographical range. — From the Andaman and Nicobar Islands to the Philippine, 

 Bonin, Marehall, and Tonga Islands, and Torres Strait. 



Bathymetrical range. — From the shore line down to 54 meters. 



Type locality. — The types (apparently syntypes) of this species were three speci- 

 mens from Amboina in the Gottingen Museum and one from the Tonga Islands in the 

 Hamburg Museum. If the type locality is to be restricted, then Amboina is to be 

 preferred, provided the specimens are still in existence, especially as it is the more 

 central in the geographical range of the species as Icnown at present. 



History. — About 20 years before this species was described a specimen of it had 

 been received by the Godeffroy Museum at Hamburg where it had received the manu- 

 script name of Antedon macropygus from Professor Liitken. 



While determining the collection of comatulids obtained by Dr. J. Brock at 

 Amboina in 1884-85, Hartlaub found this form which he recognized as representing a 

 new type, describing it in his preliminary report (1890) under the very appropriate 

 name of Antedon nana. In the Hamburg Museum he found another specimen of this 

 species from the Tonga Islands bearing Liitken's name macropygus. This locality he 

 mentioned in the preliminary report, giving the data regarding the origin of the exam- 

 ple — it had formed part of the Godeffroy Museum collection — in his final memoir (1891). 



For 19 years nothing further was published regarding this interesting form until in 

 1909 the present author recorded it from Singapore where it had been collected in 1906 

 and 1907 by Mr. Svend Gad, the Danish Consul at that port, and from the Nicobar 

 Islands where it had been found by the Oalathea expedition; and in another paper from 

 Jolo in the Philippines.
