of the character of this articulation. Hartlaub said it was remarkable that Carpenter 

 did not notice a feature that is very striking in the specimen before him, namely that 

 the second bracbial of the outermost arms arising from each IIIBr series carries a 

 much longer pinnule than the second brachial of the inner arms, so that each post- 

 radial series shows eight very long pinnules. That this feature was not noticed by 

 Carpenter was due to the fact, so Carpenter informed Hartlaub by letter, that the 

 type specimen was not well preserved and most of the lower pinnules were broken. 



Hartlaub's description of Antedon andersoni follows his discussion of species 

 belonging to the Palmata and Spinifera groups. He said that andersoni can not be 

 included in either of these groups, although it belongs to Carpenter's Series III. 



In 1895 Prof. Rene" Koehler recorded a specimen from the Bay of Amboina that 

 had been collected by Maurice Bedot and C. Pictet. He remarked that Carpenter 

 had placed this species in the Elegans group, but Hartlaub believed it could not be 

 placed there but instead should form a special group in the genus Antedon. He said 

 that he agreed absolutely with Hartlaub. 



In my first revision of the old genus Antedon published in 1907 Antedon andersoni 

 was made the type of the new genus Pontiometra. In a paper including all the names 

 that had been used for Recent crinoids published in August 1908, I said that the 

 original description of this species was based on a much mutilated individual and in 

 addition contained some misleading statements. The first good description was said 

 to be that by Hartlaub. In December 1908, a specimen was recorded from Albatross 

 station 5146 in the Philippines. 



In my revision of the families Thalassometridae and Himerometridae published in 

 January 1909, Pontiometra andersoni was listed, and Antedon (Oxymetra) finschii was 

 said to appear to be most closely related to this species. In May 1909 a new species, 

 Pontiometra insperatus, was described from Albatross station 5145 in the Philippines. 

 In a paper on the crinoids of the Copenhagen Museum published in 1909 five specimens 

 were recorded from Singapore, and notes were given on them. The specimen collected 

 by the Albatross in the Philippines (at station 5146) was said to have about 120 arms. 



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

 gave notes on a specimen from New Caledonia, and in another paper published in the 

 same year I compared the division series and arms of this species with those of Epi- 

 metra nympha. In a paper on the crinoids of the Hamburg Museum published on 

 November 7, 1912, I recorded a specimen from the Pelew Islands, which was one of 

 those previously recorded by Hartlaub, one from Cebu, and some arm fragments from 

 Jolo (Sulu) . In a paper on the crinoids of the Berlin Museum published on November 

 20 of the same year I recorded fragments from Singapore. In a memoir on the 

 crinoids of the Indian Ocean published in 1912 a specimen was recorded from Padaw 

 hi the Mergui Archipelago, and the synonymy of the species was given together with 

 a list of the localities from which it is known. 



In 1913 Dr. August Reichensperger recorded and described a very large specimen 

 which had been collected by Dr. H. Merton at Little Kei, or Roa, Island. 



In my report on the Recent crinoids of the Siboga expedition published in 1918 

 I recorded and gave notes upon a specimen from station 310, and also gave the 

 synonymy of the species.
