A MONOGRAPH OF THE EXISTING CRINOIDS 37 



The full report on the comatulids of the Gazelle expedition was published on 

 June 1. In this report the fauna of all the coasts of Australia is said to be purely 

 tropical, reaching its minimum intensity along the southern shore and not extending 

 to Tasmania nor New Zealand so far as Icnown. The species recorded are: 



Capillaster multiradiata (including Comatula fimhriata, Adinometra borneensis, 

 and Adinometra coppingeri) . 



Comanthus briareus (including Adinometra divaricata) . 

 Comaster typica. Dichrometra palmata. 



Comanthus rofalarid. Cyllometra, sp. 



Zygometra microdiscus. Cyllometra studeri. 



Zygometra elegans. Oligometra bidens. 



Dichrometra protedus. Ptilometra dorcadis. 



The curious disk of the specimen of Capillaster multiradiata, which has extensive 

 subtegminal cavities, is described. 



Carpenter considered his Antedon fluduans a synonym of Bell's previously 

 described Antedon elegans, which was misunderstood by him on account of an error 

 in the original description. Exception is here taken to this view; on the basis of a 

 large series of specimens from Singapore and the Philippine Islands determined as 

 fluduans, this form is considered as quite distinct, and the differential characters are 

 given. 



A complete bibliography of the Uterature on Australian crinoids is appended. 



The previous revisions of the family Comasteridae had not proved satisfactory, 

 and on June 7 another and far more radical revision was published in which the 

 included species were distributed among 11 genera, of which 5 were new. Keys to 

 all the genera are included, the new genera are described in detail, the genotype and 

 the range of all 'the genera are given, and three new species, the types of new genera, 

 are described. The genera accepted are: 



Comatilia, (genotype Comatilia iridometriformis A. H. Clark, 1909). 



Comatula (genotype Comatula Solaris Lamarck, 1816). 



Cominia, gen. nov. (genotype Comanthus decameros A. H. Clark, 1908). 



Comactinia, gen. nov. (genotype Aledo echinoptera J. Miiller, 1841). 



Leptonemaster, gen. nov. (genotype Leptonemaster venustus, sp. n.). 



Comissia, gen. nov. (genotype Comissia liitkeni, sp. nov . = Comaster coppingeri 

 A. H. Clark, 1908 [not of Bell], m part). 



Capillaster (genotype Actinometra sentosa P. H. Carpenter, 1888). 



Nemaster, gen. nov. (genotype Nemaster grandis, sp. nov.). 



Comatella (genotype Adinometra nigra P. H. Carpenter, 1888). 



Comaster (genotype Comatula multiradiata. Lamarck, \816 — Alecto multiflda J. 

 Miiller, 1841). 



Comanthus (genotype Comanthus intricata A. H. Clark, 1908). 



It is suggested that the Comanthus rotalaria {"Adinometra parvicirra") recorded 

 by P. H. Carpenter from "Peru" may have come from Peru or Francis Island in the 

 Gilbert group instead of from the South American country of that name.
