224 F. JEFFREY BELL. 



I have given a systematic list of the species with references sufficient to make clear what 

 is meant, and aid in any further research that it may be desirable to make ; the nature of 

 the bottom is stated, and in many cases the frequency or rarity of the species is mentioned. 



CRINOIDEA. 



I. Genus Antedon. 



Immature forms — not identifiable — were dredged on 10 occasions, sometimes in considerable 

 numbers, between 19 and 37/ (fathoms), and a few were also secured by diving off the west 

 reef of Hulule. They seem to especially frequent the inner ends of the passages, where they 

 embouch into the lagoons; in all cases the bottom is recorded as having rubble or coral, with 

 perhaps sand or weed. 



1. Antedon laevissima. 



Comatula laevissima Grube, J.B. Schles. Ges. liii. (1875), p. 74. 



Antedon laevissima, P. H. Carpenter, Chall. Rep. Comat. (1888), p. 197. 



I still hope to be able to obtain the late Dr P. H. Carpenter's notes on Grube's 'type.' 



Dredged eight times in seven atolls between 20 and 37/., usually from a hard sand or 

 shell bottom \vith some weed. In one dredging, 37 /., in the middle but just within the 

 N. passage of Suvadiva, some adults and thousands of the immature forms of this species of 

 Crinoid — and no other — were obtained. 



2. Antedon milherti. 



Comatula (Alecto) milherti, Midler, MB. Akad. Berl. 1846, p. 178. 

 Antedon milherti, P. H. Carp. Chall. Rep. Comat. (1888), p. 194. 

 Suvadiva, 43/, sand, strewn with dead oyster shells. 



3. Antedon palmata. 



Comatula {Alecto) palmata, Mtiller, Physik. Abhandl. Akad. Berlin, 1847 (1849), p. 261. 



Antedon palmata, P. H. Carp. Chall. Rep. (1888), p. 226. 



Kolumadulu, 38/, mud and weed, and Mulaku, 40/, weed, fine sand and rubble. 



4. Antedon indica. 



Comatula indica, E. A. Smith, Ann. Mag. XVII. (1876), p. 406; Phil. Trans. 168 (1879), 

 p. 564. 



Antedon indica, P. H. Carp. Chall. Rep. (1888), p. 225. 

 From the west reef of Hulule, Male Atoll, among corals. 



5. Antedon variipinna. 



Antedon variipinna, P. H. Carp. J. Linn. Soc. Lond. XVI. (1882), p. 506 ; id. Chall. Rep. 

 (1888), p. 256, ihique citata. 



S. Nilandu, 19/, at the seaward end of a passage, living corals.
