514 BULLETIN 82, UNITED STATES NATIONAL MUSEUM 



from b quotation from Lutken published by Carpenter in 1879 and was understood 

 in the sense in which it was used by Carpenter in the Challenger report on the coma- 

 tulids. Bui the protecta of the Challenger report on the comatulids (1888) is not the 

 same as the protecta of the Challenger report on the stalked crinoids (1884), the pro- 

 tecta mentioned in Carpenter's paper on the comatulids of the Leyden Museum (1881), 

 or Lutken's protectus quoted by Carpenter (1879), all of which are Stephanometra 

 ]in<tectus (see page 443). 



In another paper published in 1909, I recorded, under the name of Dichrometra 

 protectus, two specimens from Bougainville Island and another from Salawatti, and 

 also, under the name of Dichrometra palmata, two additional specimens from Salawatti. 

 All these had been secured by the German steamer Gazelle. 



In a paper on a collection of crinoids belonging to the Zoological Museum at 

 Copenhagen published in 1909, 1 recorded, under the name of Dichrometra protectus, 

 specimens from Fiji, Johorc Strait, and Singapore. 



In a paper on the crinoids of the coasts of Africa published in 1911, I recorded 

 Dichrometra protectus from Suez Bay and Suakim Harbor, taking these records from 

 Chadwick, and said that it ranges eastward to Hongkong, the Philippines, Fiji, and 

 Tonga. I recorded D. palmata ( = klunzingeri) from various localities in the Red 

 Sea and said that it ranges eastward to the Tonga Islands. 



In a paper on the crinoids of the Paris Museum published in 1911, I recorded 

 Dichrometra protectus from New Caledonia, Java, the Philippines, Zamboanga, 

 Philippines, and Pulo Condor, Cochinchina, and gave notes on the specimens. 1 

 mentioned that I had foimd the manuscript name Comatula dividuus with the speci- 

 men from Java, and the manuscript name Comatula polyactinis with the specimen from 

 Zamboanga. 



In a discussion of the crinoids of the Leyden Museum published in 1911, I placed 

 Carpenter's Antedon brevicuneata and A. imparipinna in the synonymy of Dichrometra 

 protectus, and gave notes on the type specimen of the former. Under the name 

 Dichrometra laevicirra I gave notes on the type specimen of Carpenter's Antedon 

 laevicirra and said that I should not be surprised if it eventually proved to be identical 

 with Dichrometra protectus. 



Under the name of Dichrometra protectus in 1911 I recorded and gave notes upon 

 a typical specimen from Ugi, Solomon Islands. 



In a paper on the crinoids of the Hamburg Museum published in 1912, I placed 

 lepida Hartlaub, aequipinna and imparipinna Carpenter, and brevicuneata Hartlaub, 

 1891, under the synonymy of Dichrometra protectus, and recorded specimens from 

 Tonga and Fiji (the types of lepida), no locality (the types of aequipinna and impari- 

 pinna, and two additional specimens), Hongkong, Mortlock Island, and Isabela, 

 Basilan, and gave notes on them. 



In a paper on the crinoids of the Berlin Museum also published in 1912, I re- 

 corded and gave notes on specimens from the Tonga Islands, New Guinea, Java, 

 Singapore, Bougainville Island, and Salawatti, and also on one with no locality label. 



In my memoir on the crinoids of the Indian Ocean published in 1912, as synonyms 

 under Dichrometra protectus I placed Comatula (Alecto) palmata J. Miiller, 1849 (in 

 part), Comatula dividua Dujardin and Hupe, 1862, Comatula pohjuctinis Dujardin 

 and Hupe\ 1862, Antedon protectus Lutken, 1874 and 1879, Antedon brevicuneata P. H.
