A MONOGRAPH OF THE EXISTING CRINOIDS 329 



It was first described by me under the name of Amphimetra africana in 191 1 from 

 a specimen from Bagamoyo in the Berlin Museum. At the same time two other 

 specimens belonging to the British Museum, one from Zanzibar and one from Waxin 

 (also spelled Wazin and Wasin), were recorded. 



In a memoir on the crinoids in the Berlin Museum published in 1912 the type 

 specimen was mentioned, and four smaller specimens collected with it were recorded. 



In the memoir on the crinoids of the Indian Ocean published in 1912 I listed 

 Amphimetra africana and gave as the habitat Bagamoyo, Zanzibar, and Wazin. 

 Under Heterometra savignii I listed one specimen from Kurrachi and seven from the 

 Straits of Ormuz and gave brief notes on them. Recent reexamination of these 

 specimens has shown that they represent not savignii but the very different africana. 



In my notes on the recent crinoids in the British Museum published in 1913, I 

 briefly described the specimens of Amphimetra ajricana from Zanzibar and Waxin. 

 Under Heterometra savignii I recorded and gave notes on seven specimens from 

 Kurrachi. These were the specimens upon which Carpenter had based his record of 

 Kurrachi for this species in the Challenger report. Of these specimens I said, "No 

 differences could be detected between these specimens and those from the Gulf of 

 Suez." 



The only specimen from Kurrachi at hand certainly is not savignii, as is shown by 

 the strongly carinate lower pinnules. It appears to represent africana. The brief 

 notes given apply to africana better than they do to savignii, although the chief 

 differential features — the strongly carinate lower pinnules and very short distal 

 brachials of africana — are not mentioned. There is, of course, the possibility that 

 Carpenter and I were correct in our determinations and that both savignii and africana 

 occur at Kurrachi, but this is quite improbable. 



In 1916 Dr. Robert Hartmeyer corrected the type numbers on the specimens of 

 Amphimetra africana in the Berlin Museum. 



In my report upon the unstalked crinoids of the Siboga Expedition published in 

 1918 I transferred africana from Amphimetra, under which genus it had been placed 

 on account of its very short oblong distal brachials, to Heterometra, placing it in a 

 key to the species of the latter genus where the range was given as "German Southeast 

 Africa, Zanzibar, and British East Africa." In the same key the range of H. savignii 

 was given as "Red Sea to the Persian Gulf and Kurrachi." The last two localities 

 should have been placed under africana.
