polyactinia, which I found in the jar with the specimen from Zamboanga collected by 

 Hombron and Jacquinot on the Astrolabe expedition in 1841, and Comatula dividua, 

 which I found with a specimen from Java collected by M. Philibert. 



In 1874 Prof. Christian F. Liitken listed Antedon protectus from the Tonga Islands. 

 The name is a nomen nudum, but the specimens distributed under it include both this 

 species and Stephanometra protectus. 



Dr. P. H. Carpenter in 1879 assigned palmata to the genus Antedon as understood 

 by him, also placing dividua, and polyactinis (sic) which he had examined hi the Paris 

 Museum in that genus. 



In 1881 Carpenter described Antedon brevicuneata from a specimen in the Leyden 

 Museum from Amboina, and Antedon laevicirra from a specimen hi the same museum 

 that had been collected by von Rosenberg hi the Aru Islands. At the same time he 

 mentioned the Antedon protecta of Liitken. 



In 1882 he described Antedon aequipinna from a specimen without locality in the 

 Hamburg Museum, and Antedon imparipinna from another specimen without locaility 

 in the same Museum. 



Prof. F. Jeffrey Bell in 1882 published specific formulas for Antedon palmata, A. 

 brevicuneata, and A. laevicirra. Early in 1883 Carpenter published revised formulas 

 for these forms, and also formulas for Antedon protecta, A. aequipinna, and A. im- 

 paripinna. 



In 1888 Bell recorded Antedon palmata from Tuticorin, Madras, from collections 

 made by Edgar Thurston, of the Madras Government Central Museum, and also 

 listed it as occurring in the Bay of Bengal. The specimens upon which this record 

 was based represent both Lamprometra palmata and Stephanometra protectus. 



In the Challenger report on the comatulids published in 1888 Carpenter included 

 under the name Antedon palmata both Lamprometra klunzingeri from the Red Sea 

 and L. palmata. This is evident from the range that he gave for the species Red 

 Sea; Ceylon. 



In the remarks under the Palmata group he said that isolated specimens occur at the 

 Sandwich Islands on the east and at Ceylon on the west. The mention of the Sand- 

 wich Islands was based upon some specimens of the present species that had been sent 

 him by the Museum of Comparative Zoology with the Blake collection, which were 

 later (1912) recorded and described by Hartlaub. 



Carpenter described as new species and figured Antedon conjungens, based upon 

 two specimens from the Zebu reefs ; Antedon similis, based upon a single specimen from 

 station 174; and Antedon occulta, based upon three specimens from station 174. 

 In his key to the species of the Palmata group he included protecta Liitken, MS., and 

 he mentioned this form in his discussion of Antedon conjungens and A. occulta. His 

 interpretation of protecta was based upon a single specimen that had been sent him 

 by Prof. Sven Loven, which represented the present species. In the Challenger report 

 on the stalked crinoids (1884) he had used the name protecta for the very different 

 Stephanometra protectus (see page 443). The range of protecta he gave as Fiji; Tonga. 



In 1889 Carpenter recorded and gave notes on a specimen identified as Antedon 

 conjungens from the Mergui Archipelago and compared it with A. protecta. 



In 1890 Dr. Clemens Hartlaub described Antedon lepida from two specimens from 

 the Tonga Islands in the Hamburg Museum, Antedon protecta (Liitken, MS.) from
