ACTINOMETRA, spp. 



Actinometra P. H. CARPENTER, Bull. Mus. Comp. Zool., vol. 9, No. 4, p. 154. 



Doctor Carpenter here noted that Actinometra cumingii and two or three unde- 

 scribed species from China, Japan, and Sumatra are the only 10-armed comasterids 

 in the Eastern Hemisphere which do not belong to the Solaris type. 



Actinometra cumingii is the young of Comatula pectinata. The species from 

 China probably refers to a specimen of Comactinia echinoptera erroneously labeled 

 Hong Kong which was sent to Carpenter from the Museum of Comparative Zoology at 

 Cambridge, Mass., with the Blake collection. The species from Japan may have been 

 included in Professor Doderlein's collection, or it may refer to the type specimen of 

 Comatulides decameros in the Copenhagen Museum. If it was in the Doderlein 

 collection it was undoubtedly a species of Comissia. I have not been able to locate the 

 specimen or specimens upon which the mention of Sumatra is based. Very few 

 crinoids have ever been recorded from Sumatra.

Actinometra P. H. CARPENTER, Quart. Journ. Microsc. Sci., vol. 27, 1887, p. 386. 



Carpenter here says that there is no sign of sacculi in an Actinometra from a 

 Challenger station near the Kei Islands, in 9 specimens from Cape York in the Chal- 

 lenger dredgings, or in specimens from 6 different Blake stations near Barbados, 

 Montserrat, Martinique, and St. Vincent. The specimens referred to are all given 

 under the proper species in the preceding pages.

Actinometra VON GRAFF, Challenger Reports, Zoology, vol. 20, pt. 61, 1887, pp. 3, 9. 



Professor von Graff described a myzostome from an undetermined species of 

 Actinometra from the Moluccas. 



ACTINOMETRA, sp. 



Actinometra, sp. H. CARPENTER, Challenger Reports, Zoology, vol. 26, pt. 60, 1888, p. 329. 



Carpenter mentioned that a comasterid of the Parvicirra group is found at 

 Tahiti. This is the only reference to this specimen. 



ACTINOMETRA, spp. 



Actinometra BELL, in GARDINER, Fauna and Geography of the Maldive and Laccadive Archipelagoes, 

 vol. 1, pt. 3, 1902, p. 225. 



Professor Bell said : 



Genus Actinometra. Young forms were obtained off the coral masses of 

 the west reef of Hulule. It is noticeable that neither this genus nor Antedon 

 was found in the lagoon nor on the reefs of Minikoi.
