In 190.S, under the name of Himerometra milberti, I recorded a specimen from 

 Albatross Btation 5100 in the Philippine Islands. This specimen has been responsible 

 for much of the confusion in v hicb the genus Amphimetra has been involved. It was 

 identified on the basis of the description and figures given by Carpenter in the Chal- 

 I, ngi r report, and for a Long nine 1 regarded it as a typical example of milberti, basing 

 all inv ideas of that species upon it. It is described herein as the type specimen of 

 Amphimetra epectabilis. 



In a revision of the family Himerometridae published in 1909 milberti and tessel- 

 laia were transferred to the new genus Amphimetra. Later in 1909 I compared my 

 new species moUeri with milberti, my concept of the latter being based upon the 

 specimen from Albatross station 5100. 



In 1910 I examined the type specimen of Comatvla jacquinoti at the Paris Museum 



and in 1911 published a description of it, referring it to Amphimetra milberti. I failed 



ee the type specimen of milberti in the same museum and placed jacquinoti in the 



synonymy of milberti on the basis of the comparison made by Carpenter in the 



( tall, nger report. 



In a memoir on the crinoids collected by the Hamburg Southwest Australian 

 Expedition, which was published in 1911, I gave notes under the name Amphimetra 

 discoidea, on a specimen presumably from the vicinity of Perth. I said that in this 

 specimen the cirri are stouter than usual, approaching the condition found in A. milberti 

 (that is, the specimen of A. spectabilis from Albatross station 5100), although the 

 individual should undoubtedly be referred to A. discoidea. All the additional locali- 

 ties given refer to A. discoidea except Port Moresby and Hood Lagoon, New Guinea, 

 which refer to A. papuensis. 



In a memoir on the recent crinoids of Australia, also published in 1911, I said 

 that the Alert collected a specimen of Amphimetra milberti (=tessellata) at Port Molle 

 all the other specimens listed in the Alert report from Port Molle belonging to A. 

 discoidea. I said that milberti ranged from the Mergui Archipelago to Borneo and 

 the Philippine Islands and southward to northern Australia. The locality Mergui 

 Archipelago was based upon Carpenter's record (=A. molleri) ; Borneo was based 

 upon Grube's Comatvla laevissima {=A. molleri); and Philippine Islands was based 

 upon the specimen from Albatross station 5100 (=A. spectabilis). 



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

 mentioned the specimen presumably from the vicinity of Perth under the name of 

 Amphimetra discoidea. 



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

 Amphimetra milberti (including jacquinoti), giving the synonymy and a list of the 

 localities from which it is known. The species represented at the localities given are 

 as follows: Amphimetra laevipinna (Canton) ; Amphimetra discoidea (Prince of Wales 

 Channel, Torres Strait; Port Molle); Amphimetra tessellata (Amboina; Ceram; Port 

 Molle); Amphimetra molleri (Panay and Zamboanga [Challenger stations 203, 212]; 

 Padan [=Padau] Bay, Mergui Archipelago; North Borneo; Ceylon); Amphimetra 

 spectabilis (Philippine Islands). Alecto tessellata was given in the unidentifiable list, 

 with a translation of the original description. 



In his memoir on the comatulids collected by the United States Coast Survey 

 steamer Blake, published in 1912, Dr. Clemens Hartlaub described in considerable
