A MONOGRAPH OF THE EXISTING CRINOIDS 193 



Danish Expedition to the Kei Islands; Dr. Th. Mortensen; Vatek van Tooal; 

 about 2 meters; rocky coast; March 23, 1922 (2). 



Siboga station 209 ; anchorage off the south point of Kabaena Islands (off south- 

 eastern Celebes); reef [A. H. Clark, 1918] (1, Amsterdam Mus.). 



Geographical range. From Singapore, Cochinchina, and the Philippines south- 

 ward to Kabaena Island and the Kei Islands, and eastward to the Admiralty Islands. 



Bathymetrical range. Littoral and down to 38 meters. 



History. The first known specimen of this species was recorded by Dr. Clemens 

 Hartlaub from Cochinchina in 1891. He referred it to a new species from Amboina, 

 which he described under the name Antedon [Himerometra] crassipinna, but he men- 

 tioned certain features whereby it differed from the three specimens he had from 

 Amboina. 



In 1908 I described the species from a specimen dredged by the Albatross in the 

 Philippines at station 5139 and at the same time recorded another specimen from 

 station 5147. In 1911 I recorded an additional example, which had been collected by 

 the Albatross at Palawan. 



In my monograph of the crinoids of the Indian Ocean published in 1912, I gave 

 this species from the Philippines and from St Matthias Island, the latter locality 

 being taken from the labels of unrecorded specimens in the Hamburg and Berlin 

 Museums. Hartlaub's specimen from Cochinchina I included with a query under 

 H. crassipinna. In a paper on the crinoids of the Hamburg Museum published in the 

 same year, I referred Hartlaub's Cochinchina specimen definitely to H. magnipinna, 

 and recorded one specimen from Isabela, Basilan, another from Ekalin, St. Matthias 

 Island, and three from Pitilu in the Admiralty Islands. In a paper on the crinoids of 

 the Berlin Museum published two weeks later, I recorded another specimen from St. 

 Matthias Island. 



In 1918 I recorded and gave notes upon a very small specimen which had been 

 dredged by the Siboga at station 209. 



Dr. Torsten Gisle'n in 1924 described and figured various structural features of this 

 species, but did not give the origin of his specimen. 



In 1933 I recorded a specimen from Nassi Besar in the collection of the Buitenzorg, 

 Java, Museum, and in 1934 I recorded three specimens from Singapore, one dated 

 1899, in the collection of the Raffles Museum, Singapore. 



In 1936 Dr. Gislen recorded and gave notes upon a young specimen from Pulo 

 Condor, Cochinchina.
