occulta V. II. Carpenter), Ramesvaram, Gulf of Mannar, Blanche Bay, New Britain, 

 Fiji (labeled aeguipinma), Tonga (labeled protectus), the Andaman Islands, and 

 \am-Zit [aland. I said I could not sec that the type of Carpenter's Antedon similis 

 presents any valid characters by winch it may be separated from the earlier Antedon 

 protectus. It also appears to be the same thing as Boll's Ant/don moorei, though the 

 typo of the latter is a young and immature individual with the dorsal processes on the 

 outer cirrus segments a trifle more conspicuous. The type of similis is regularly 

 30-armed and is in every way stouter than the type of moorei; the cirrus segments 

 are never quite so long as broad, while the earlier are longer than broad in moorei. 

 The pinnules of the type of similis resemble those of certain varieties of protectus. 



In a list of unidentified species Antedon moorei was included, and notes on the 

 type specimen were given. 



In 1915 Dr. Hubert Lyman Clark described Lamprometra callipecha from a single 

 specimen from Mer Island, Torres Strait, and in the same year he recorded two speci- 

 mens of Dichrometra protecta and one of D. tenera from Ceylon. 



In my memoir on the unstalked crinoids of the Siboga expedition published in 

 1918, I included under Lamprometra protectus as synonyms Comatula (Alecto) 

 palmata J. Midler (in part), Comatula dividua and C. polyactinis Dujardin and Hupe, 

 Antedon protectus Lutken [error], A. brevicuneata P. H. Carpenter, A. laemcirra P. H. 

 Carpenter, A. protecta P. H. Carpenter, 1881 [error], A. aequipinna P. H. Carpenter, 

 .1. i inparipinna P. H. Carpenter, A. palmata Bell, 1888, and Thurston, 1894 (in part), 

 A. protecta P. H. Carpenter, 18S8, A. conjungens P. H. Carpenter, A. similis P. H, 

 Carpenter, A. occulta P. H. Carpenter, A. indica Bell, 1899, A. lepida Hartlaub, A. 

 protecta Hartlaub, A. amboinensis Hartlaub, A. palmata Hartlaub, 1891 (in part), A. 

 subtilis Hartlaub, A. okelli Chadwick, Himerometra helianthus, or heliaster A. H. 

 Clark [error], Lamprometra brachypecha H. L. Clark, and L. callipecha H. L. Clark. 

 Specimens were recorded from 16 Siboga stations, and notes were given on them. 



In 1921 Dr. H. L. Clark took exception to my placing his Lamprometra brachy- 

 pecha in the synonymy of L. protectus (=palmata) and maintained it as a distmct 

 species. His Lamprometra callipecha, which I had placed in the synonymy of the 

 present species in 1918, he regarded as a distinct species under the name of Stepha- 

 nometra callipecha. It is considered herein as a synonym of Stephanometra indica 

 (see page 436). 



Gisldn in 1924 discussed in detail the structure of this species and recorded a 

 specimen from Trincomalee, Ceylon. 



In a paper on some recent crinoids in the collection of the British Museum pub- 

 lished in 1929, I recorded, under the name Lamprometra palmata, specimens from the 

 Maldive Islands, Christmas Island, and the Macclesfield Bank. I said that this was 

 the species I had previously called Lamprometra protectus (Lutken). I remarked that 

 it is evident from Midler's original description and from the locality he gave (India — 

 probably the Dutch East Indies) that it was this species that he had, and not that 

 from the Red Sea. The latter must be known as Lamprometra klunzingeri (Hartlaub). 



In 1923 I recorded a large number of specimens from various localities in the 

 Indian Museum, and in 1934 I recorded additional specimens from Singapore and 

 Christmas Island in tin' Raffles Museum, Singapore.
