A MONOGRAPH OF THE EXISTING CRINOIDS 55 



The following new species were described: 



Amphimetra flora . Hybometra senta. 



The following new genus was described : 



Hybometra (genotype Hybometra senta, sp. nov.). 



The following new generic names appear: 



Oligometrides (no diagnosis; the name appears in combination as Oligometrides 

 adeonae [Lamarck]). 



Aglaometra (no diagnosis; the name appears in combination as Aglaometra valida 

 [P. H. Carpenter] and Aglaometra incerta [P. H. Carpenter]). 



Anthometra (no diagnosis; the name appears in combination as Anthometra 

 adriani [Bell]). 



Florometra (no diagnosis; the name appears in combination as Florometra magel- 

 lanica [Bell]). 



The following new specific names are included: 



Neocomatella europaea (a few characters are given). 



Neocomatella atlantica (a few characters are given). 



Amphimetra papuensis (a few characters are given). 



Hathrometra norvegica (a few characters are given). 



On January 4, 1914, a preliminary paper was published showing the circulation 

 of the abyssal water of the oceans as worked out from a study of the distribution of 

 bottom living organisms, particularly crinoids; a much more detailed discussion of 

 the same subject was published on February 25. 



The crinoids collected by the Australian fisheries steamer Endeavour on the 

 coasts of Western Australia were described in a paper published in 1914. In this 

 the following species were recorded: 



Capillaster sentosa. Zygometra elegans. 



Capillaster multiradiata. Amphimetra discoidea. 



Comatulella brachiolata. Tropiometra afra. 



Comatula purpurea. Neometra gorgonia, sp. nov. 



Comanthus (Varna) annulata. Neometra conaminis, sp. nov. 



Comanthus (Vania) parvicirra. Ptilometra macronema. 



In connection with the description of Neometra gorgonia and TV. conaminis the 

 genus Neometra is discussed in great detail, and the characters of all the included 

 species are given. 



A series of papers now appeared containing a preliminary exposition of many 

 points in the general biology of crinoids and of marine animals in general; the sub- 

 jects dealt with were the relation between the recent crinoids and the temperature of 

 their habitat (June 20 and December 4), the correlation between the bathymetrical 

 and the geographical range of the recent crinoids, the Atlantic Ocean as primarily 

 an inland sea, and the geographical divisions of the recent crinoid fauna. 



From time to time a considerable amount of study had been devoted to the corre- 

 lation between the marine and the terrestrial and the past and present faunas, and 

 more or less extended observations on these subjects appeared in a series of papers
