Siboga station 144; anchorage north of Salomakiee (Damar) Island, southern 

 Moluccas; 45 meters; coral and lithothamnion ; August 7-9, 1899 [A. H. Clark, 1918] 

 (1, Amsterdam Mus.). 



South of the eastern end of Java (lat. 8°47' S., long. 114°38' E.); 30-36 meters; 

 November 10, 1908 [A. H. Clark, 1933] (1, Buitenzorg Mus.). 



Investigator station 387 ; southwest of the mouths of the Irrawaddy River (lat. 

 15°25' N., long. 93°45' E.); 73-89 meters [A. H. Clark, 1912] (1, I. M.). 



Geographical range. — From the southern Philippines and the Gulf of Martaban, 

 Burma, southward to the Kei and Damar Islands and eastern Java. 



Bathymetrical range. — From 36 (?30) to 100 meters. 



History. — The name P[tilometra] pulcherrima first appeared as a nomen nudum 

 in 1909. Speaking x)f Ptilometra dorcadis, new species, I wrote that "Its remarkably- 

 robust aspect differentiates it from P. macronema in about the same degree that that 

 species is differentiated from P. trichopoda and P. pulcherrima of the Philippine 

 Islands." In a paper written before the one just noticed though published later in 

 1909 Ptilometra pulcherrima was described in detail from a specimen from Albatross 

 station 5252. In 1911 in the description of Asterometra (—Pterometra) magnipeda 

 this species was said to be most nearly related to Asterometra pulcherrima, which was 

 identified by a footnote reference to the original description of Ptilometra pulcherrima. 

 In 1912 I recorded a specimen that had been dredged by the Royal Indian Marine 

 Survey Steamer Investigator southwest of the mouths of the Irrawaddy River which 

 was said to agree well with the type and with another in the Siboga coDection. In 

 my report on the unstalked crinoids of the Siboga expedition published in 1918 

 pulcherrima was referred to the genus Pterometra. A specimen was recorded from 

 Siboga station 144 and notes on it were given. A colored figure and a photograph of 

 the specimen were published. 



In 1933 a specimen was recorded, with notes, from south of the eastern end of 

 Java. Dr. Torsten Gisl^n in 1934 discussed various structural features of this 

 species. In 1936 I recorded and gave notes on a specimen from Willebrord Snellius 

 station 60*.
