A MONOGRAPH OF THE EXISTING CRINOIDS 535 



he said that it resembled bella in the irregular division of the postradial series. This, 

 however, is merely a juvenile feature. 



In my first revision of the old genus Antedon published in 1907, palmata and 

 klunzingeri were referred to the new genus Himerometra. 



In 1908 Herbert Clifton Chadwick recorded and gave notes on several specimens 

 from Misharif Island and one from Suez that he called Antedon palmata, and one from 

 Suez Bay and four from Suakim Harbor that he called Antedon imparipinna. 



In my revision of the family Himcrometridae published in 1909, klunzingeri and 

 palmata were referred to the new genus Dichrometra. 



In a paper on the crinoids of the Leyden Museum published in 1911 I gave notes 

 on the specimen from Djeddah previously recorded by Hartlaub, which I had ex- 

 amined in 1910. 



In my memoir on the crinoids of the coasts of Africa published in 1911, 1 included 

 Dichrometra protectus (=palmata), repeating Chadwick's records for Antedon impari- 

 pinna, D. palmata (the present species), giving Chadwick's records and also "Red 

 Sea," and D. klunzingeri, with the localities Koseir and Ras-el-Millan, the latter being 

 taken from a specimen in the Berlin Museum. Under D. palmata was included 

 Comatula scita as a synonym. This species was said to range eastward to the Tonga 

 Islands, following Hartlaub. 



In a paper on the crinoids of the Paris Museum published in 1911, 1 recorded and 

 gave notes on a specimen of Dichrometra palmata from the Red Sea collected by M. 

 Botta in 1856 (in reality 1836), and on two specimens from the Red Sea collected by 

 M. Jousseaume in 1893-1898. 



In a paper on the crinoids in the Berlin Museum published in 1912, I recorded 

 and gave notes on eight lots of specimens from Um-el-Jerman, Red Sea, without 

 further data (four lots, three collected by Hcmprich and Ehrenberg), Ras-el-Millan, 

 Dar-es-Salaam, and an unknown locality. The record from Dar-es-Salaam, which 

 was said to be on the Red Sea, was based on fragments. Hartlaub's Antedon klun- 

 zingeri was said to be identical with this species, which was given as Dichrometra 

 palmata. 



I noted that Hartlaub called attention to the fact that Muller in describing Alecto 

 palmata (see page 501) gave the number of arms as 35-40, whereas true palmata has 

 but 30. M tiller's description of palmata (that is, the description published in 1849) 

 was partly (in reality wholly) based upon specimens of Dichrometra protectus (=Lam- 

 prometra palmata), a 40-armed species, and he seems to have taken the arm number 

 from these. I remarked that Muller's specimens of palmata from India and from 

 Zamboanga are both representatives of protectus (=palmata). 



In a paper on the crinoids of the Hamburg Museum published in 1912, 1 recorded 

 and gave notes on a specimen from Girusah Bay that had been collected by Dr. Robert 

 Hartmeyer. 



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

 Red Sea, Suez Bay, and Suakim Harbor among the localities for Dichrometra protectus, 

 following Chadwick. I recorded specimens of D. palmata from Gwada, Baluchistan, 

 Snod Island in the Mergui Archipelago, and ?Celebes, and gave as the localities from 

 which the species was previously known "India," Red Sea, Djeddah, coral reef at 

 Misharif Island, between tide marks at Suez, Muscat, Ceylon, Java, Singapore,
