A MONOGRAPH OF THE EXISTING CRINOIDS 335 



No locality [J. Miiller, 1841]. Same [A. H. Clark, 1911] (10, Austr. M.). Same 

 [A. H. Clark, 1913] (1, B. M.). Same [Gisl6n, 1924]. 



Erroneous localities. — Zanzibar [von Martens, 1869] (= Tropiomeira carinata). 



Indies [J. Miiller, 1843, 1849; Dujardin and Hup6, 1862; P. II. Carpenter, 

 1888] (error for Australian Seas). 



Near Bohol, Philippines [von Graff, 1877, 1884] ( = Comatula pedinata). Philip- 

 pine Islands [A. H. Clark, 1911] is based on this record. 



Moluccas [von Graff, 1887] ( = Comatula pedinata). 



Dundas Strait [Bell, 1884] { = Comatuta pedinata + C. purpurea). 



Alert station 144; probably Thursday Island [Bell, 1884] { = Comatula pedinata). 



Thursday Island [Bell, 1884] { = Comatula pedinata). 



Arafura Sea [Bell, 1884] { = Comatula pedinata). 



Warrior Reef [Bell, 1884] { = Comatula pedinata). 



Geographical range. — From Hong Kong and Singapore southward to tropical 

 AustraUa, reaching the Abrolhos Islands (lat. 28° 40' S.) on the west coast and Port 

 Curtis (lat. 24° S.) on the east; possibly eastward to the Society Islands. 



Bathymetrical range. — Littoral and sublittoral, extending from the shore line 

 down to 21.9 meters; the average of 8 records is 13.3 meters. 



Remarks. — In view of the quite different aspect presented by the light-colored 

 slender-armed individuals from the northern portion of the range, it might be advisable 

 to differentiate these as Comatula Solaris gracilior, the range of which would be from 

 Hong Kong and the China Sea to Singapore and Billiton. This would restrict the 

 range of typical Comatula Solaris Solaris to the Australian coasts. 



History. — This species was originally described by Lamarck in 1816 under the 

 name of Comatula Solaris from specimens brought from Australia by P6ron and 

 Lesueur in 1803. 



In 1830 Sir Richard Owen mentioned a specimen in the museum of the Royal 

 CoUege of Surgeons identified by W. E. Leach as Comatula Solaris which was said to 

 have been brought from the Society Islands by Sir Joseph Banks. We know practi- 

 cally nothing of the crinoids of the Society Islands, and it is not unlikely that some 

 form of this species occurs there. But this specimen, which was exhibited to show 

 the ovaries and ova, has disappeared and no comasterids have since been recorded 

 from the region. 



In 1841 Johannes Miiller described in great detail under the name of Actinometra 

 imperialis a magnificent specimen without locality which he had examined in the 

 Vienna Museum. 



In 1843 Miiller published a redescription, under the name of Alecto Solaris, of 

 Lamarck's types in the Paris Museum based upon notes which had been taken for 

 him by Troschel. The locality was given as "Indien," although the specimens were 

 correctly stated to have been collected by P^ron. 



Miiller's detailed description of this species under the name Comatula (Actino- 

 metra) Solaris published in 1849 was essentially the same as his description of Actino- 

 metra imperialis published in 1841, but it was broadened so as to include some addi- 

 tional specimens which he had been able to examine and which he believed to be 

 conspecific with it. He had personally studied the types of Comatula Solaris at Paris
