A MONOGRAPH OF THE EXISTING CRINOIDS 35 



Through the courtesy of Drs. W. Weltner and E. Hartraeyer, of the Berhn 

 Museum, and of Prof. Th. Studer, of Berne, the crinoids collected in Australian 

 waters by the German steamship Gazelle had been sent to me, and on March 10 

 I published the descriptions of the two new species included; these were: 



Ptilometra dor cadis. Oligometra studeri. 



The type of Ptilometra macronema was taken at King George's Haven in south- 

 western Australia, while all the specimens which I had been able to examine were 

 from the eastern coast, mostly from Port Jackson or Sydney. There was a possi- 

 biUty, therefore, that Pt. dorcadis might turn out to be the true macronema, in which 

 event the name mulleri was suggested for the species from Sydney. 



In another paper published m March the status of the genus Encrinus is con- 

 sidered. Encrinus is said to date from Blumenbach, 1779, who included in it three 

 species : 



1. asteria {Isis asteria Linn^). 



2. mylii (or radiatus) (type of Umbellularia Lamarck, 1801). 



3. boltenii (or ouifer) (type of Boltenia vSavigny, 1816). 



This leaves asteria (Isis asteria ljimi^ = Isocrinus asteria) as the genotype of 

 Encrinus. 



The recent species are listed as follows: 



Encrinus {Encrinus) asteria. Encrinu (Isocrinus) blakei. 



Encrinus (Isocrinus) decorus. 



At the suggestion of Dr. F. A. Bather, the Indian Museum, through Dr. N. 

 Annandale, had entrusted to me for study the magnificent collection of recent cri- 

 noids which had been brought together as a result of the operations of the Royal 

 Indian Marine Surveying steamer Investigator. On April 17 a paper was published 

 containing preliminary descriptions of a number of the new species included in it. 

 These were: 



Eudiocrinus minor. Crotalometra rustica. 



Dichrometra aranea. Pacliylometra macilenta. 



Cyllometra mollis. Pachylometra investigatoris. 



Calometra magnifica. Eumetra indica. 



Calometra spinosissima. Metacrinus batheri. 



The generic name Crotalometra, used in combination with (Crotalometra) rustica 

 in the description of that species, is new. Eudiocrinus ornatus, with which E. minor 

 is compared, is a nomen nudum. 



On the same date a note was published in which a misconception in regard to 

 the type species of Agassiz' genus Comaster was rectified. The type of Comaster was 

 Comatula multiradiata Lamarck, 1816. This species was redescribed by Miiller in 

 1841 from notes made on one of Lamarck's specimens as Alecto multifida. Conse- 

 quently the type of Comaster L. Agassiz, 1836, is Alecto multifida J. Miiller, 1841 = 

 Comatula multiradiata Lamarck, 1816, not Asterias multiradiata Linn6, 1758.
