52 BULLETIN 82, UNITED STATES NATIONAL MUSEUM 



The new species described are — 



Comissia hartmeyeri. Tropiometra audouini. 



Tropiometra midouini is compared with T. indica (new name) from Ceylon. 



Dichrometra palmata is stated to be confined to the Red Sea; the individuals from 

 Singapore and New Guinea recorded as palmata represent in reality D. protedus. 



Hartlaub's Antedon klumingeri is a synonym of D. palmata, and Carpenter's 

 Antedon quadrata is a synonym of Heliometra glacialis. 



The complete report upon the crinoids of the Indian Museum, including the 

 Investigator collections, appeared on November 22 as a comprehensive memoir on the 

 crinoids of the Indian Ocean, or rather of the entire Indo-Pacific-Japanese faunal 

 region, including an historical introduction, a minute analysis of the fauna, a detailed 

 discussion of the zoogeography, by regions and by groups, keys to the orders, families 

 and genera, and a complete bibliography. 



In this the three subfamilies of Himerometridae, Himerometrinae, Stephano- 

 metrinae, and Mariametrinae, were raised to family rank. 



The following new genera were described : 



Oreometra (genotype Oreometra mariae, sp. nov.). 



Neometra (genotype Antedon multicolor A. H. Clark, 1907). 



Gephyrometra (genotype Antedon versicolor A. H. Clark, 1907). 



Pectinometra (genotype Antedon flavopurpurea A. H. Clark, 1907). 



Comastrocrinus (genotype Hypalocrinus springeri A. H. Clark, 1909). 



The following new species were described: 



Himerometra sol. Thalassometra marginata. 



Decametra arabica. Stiremetra carinifera. 



Oligometra concinna. Trichometra plana. 



Oreometra mariae. Metacrinus batheri var. gracilis. 



Comatella decora. 



The following new names were proposed: 



Himerometra pulcher (for Himerometra robustipinna A. H. Clark, 1908, not 

 Actinometra [Himerometra] robustipinna P. H. Carpenter, 1881). 



Craspedometra amboinae (for Antedon ludovici Hartlaub, 1891, in part). 

 In an appendix additional species received after the main part of the work had 

 gone to press are recorded, and the following new forms are described: 

 Comissia chadwicki. Dichrometra ciliata. 



Eudiocrinus gracilis. Colobometra (Prometra) brevicirra. 



Heterometra pulchra. Oligometra serripinna var. erinacea. 



The new subgenus Prometra (genotype Colobometra chadwicki A. H. Clark, 1911) 

 is estabUshed. 



In April, 1913, a supplement to the report upon the crinoids of Western Australia 

 collected by Doctors Michaelsen and Hartmeyer was published, and at about the 

 same time a paper on a collection of crinoids from the waters about Ireland appeared. 

 In the latter the following new species were described : 



Trichometra hibernica. Atelecrinus helgae.
