Geographical range. — From Java to northern Australia and northward to the 

 Philippines and Formosa. 



Bathymetrical range. — Littoral and sublittoral, ranging from between tide marks 

 down to 91 meters. The average of 25 depth records is 32 meters; but if the 12 

 records in which no depth is given are considered, the average is 23 meters. 



History. — This species was first mentioned by Dr. P. H. Carpenter in 1881. 

 In his original description of Comantheria alternans he said that its nearest ally 

 is a species which was discovered by Professor Semper at Pandan[on], near Bohol, 

 in the Philippine Islands, and he gave some of the characters by which the two 

 may be distinguished. 



In his description of Comantheria grandicalyx pubUshed in 1882 Carpenter said 

 that he knew of only one other Actinometra with the same number and arrangement 

 of the arm divisions as they occur in this type. This form was obtained by the 

 Challenger at Banda, and is much smaller, with a thin fiat centrodorsal. 



Prof. F. Jeffrey Bell in 1882 gave a specific formula for a new species which 

 he called Antedon briareus that had been collected by the Alert at Port Denison. 

 This he described and figured in 1884. 



In the Challenger report on the stalked crinoids published in 1884 Carpenter 

 several times mentioned Semper's specimen from the Philippines. He called it here 

 Actinometra magnijica and gave for it a specific formula. 



In 1888 Carpenter placed Bell's Antedon briareus in the genus Actinometra 

 and discussed it at considerable length. He made several references to Actino- 

 metra magnijica and included it in his key to the species of the Parincirra group. 

 The Challenger specimen from Banda which he had compared with grandicalyx in 

 1882 he described and figured under the name of Actinometra divaricata. 



In 1891 Dr. Clemens Hartlaub recorded a specimen (as divaricata) from Amboina, 

 and in 1894 Bell recorded another (as Actinometra 'parvicirra) from Baudin Island. 

 In 1895 Prof. Rene Koehler recorded this species (as divaricata) from the Sunda 

 Islands, and in another paper also from the Bay of Amboina. 



In 1908 I recorded specimens from 3 Albatross stations in the Philippines and 

 also from the Philippines Mathout definite locahty. In 1909 I recorded it from 

 6 Albatross stations in the Philippines and in another paper from a Gazelle station 

 north of Port Walcott. In 1911 I recorded it from 2 more Albatross PhiUppine 

 localities, and in an appendix to my paper on the crinoids of the Leyden Museum 

 Dr. R. Horst recorded it from west Java. 



In my report on the crinoids collected by the Hamburg southwest Australian 

 expedition in 1905, which was published in 1911, I recorded a specimen presumably 

 from the vicinity of Perth and gave Baudin Island and Bassett-Smith Bank as locali-
