A MONOGRAPH OP THE EXISTING CRINOIDS 549 



In the Hamburg Museum he found a specimen from Port Denison bearing the 

 manuscript name Actinometra brachymera of Lutken. This he determined as bennetti. 



In April, 1891, the Rev. Canon Alfred Merle Norman pointed out that Comatula 

 multiradiata Lamarck is the type of Agassiz's genus Comaster, and that this genus 

 was erected to include forms allied to Antedon in which the arms are ramified instead 

 of being simply bifurcated. He said that if there is such a form as that described 

 by Goldfuss, which several authors have doubted, it will require the intervention of 

 a new generic name, for which he suggested Goldfussia. 



Dr. Francis Arthur Bather in May, 1891, indicated that Goldfussia is preoccupied. 



Prof. F. Jeffrey Bell in 1894 recorded a specimen of this species from the Mac- 

 clesfield Bank. In 1895 Prof. Rene" Koehler recorded Actinometra robustipinna 

 from the Bay of Amboina, which had been collected by MM. Maurice Bedot and 

 P. Pictet. As the type specimen of Carpenter's Actinometra robustipinna is a species 

 of Himerometra, Professor Koehler's record is undoubtedly based upon bennetti, 

 which is the only comasterid that would fit Carpenter's description. 



In 1899 Bell recorded (as Actinometra grandicalyx) a specimen from New Britain 

 which had been collected by Prof. Arthur Willey. 



In 1909 I recorded and gave notes upon a magnificent specimen from the Pelew 

 Islands which, bearing the name Actinometra brachymera Lutken, is in the collection 

 of the Copenhagen Museum. At the same time I remarked that Professor Koehler 

 recorded a specimen of Comanthus robustipinna from Amboina, but that from his 

 description it seems probable that the example really belongs to this species, which 

 had previously been found at Amboina. I added that Carpenter's original descrip- 

 tion of robustipinna is perfectly applicable to certain specimens of bennetti. 



In 1911 in a paper on the crinoids in the collection of the Leyden Museum I 

 included in the synonymy of Comanthus bennetti the Comatula multiradiata of Gold- 

 fuss, 1832, the Actinometra brachymera (nomen nudum) of Lutken, 1877, and the 

 Actinometra peronii of Carpenter, 1881. I also stated that the type specimen of 

 Actinometra robustipinna had proved on examination to be a representative of a 

 species of Himerometra and not an Actinometra at all. In another paper on the 

 crinoids of the Paris Museum I gave notes upon the specimen of bennetti which had 

 been collected in 1803 by Peron and Lesueur. In a memoir on the crinoids of Aus- 

 tralia, also published in 1911, I repeated the synonymy given in the paper on the 

 Leyden crinoids, and gave a summary of the knowledge of this species. The western 

 extremity of the range was given as the Bay of Bengal. This referred to unrecorded 

 specimens from the Coco Islands. 



In 1912 in a paper on the crinoids of the Hamburg Museum I recorded and gave 

 notes upon the 6 specimens in that institution. Three of these, one from Jaluit and 

 2 from St. Matthias Island, had not previously been recorded. In another paper on 

 the crinoids of the Berlin Museum I listed and gave notes upon 6 specimens, 1 from 

 the South Seas and 5 from St. Matthias Island. In my memoir on the crinoids of the 

 Indian Ocean I gave a fairly detailed synonymy of this species, including references 

 to the specimen included in Lamarck's Comatula multiradiata and that recorded by 

 Bell under the name of Actinometra grandicalyx. Extended notes on 2 individuals 

 from Table Island in the Coco group were given. I appended a complete list of
