Notes. The specimen recorded by Dr. H. L. Clark from Ceylon consisted of a 

 calyx with the cirri and two arm bases attached. 



Of the two specimens from the Ceylon Pearl Oyster Fisheries station LIII one, 

 according to Chadwick, has 28 arms, and the other, now much mutilated, must 

 have had the same number when living, IIIBr series being present on the outer side 

 of both IIBr series on three of the postradial series. 



The specimens from station LVII have 20 arms. A specimen apparently cor- 

 responding to Hartlaub's variety brunnea of C. bella was obtained at this station. 



Localities. -Ganjam coast, Madras Presidency, India; 22 meters [A. H. Clark, 

 1909, 1912] (4, U.S.N.M., 35303; I. M.). 



Bengal Fisheries steamer Golden Crown; Ganjam coast; 44-45 meters; March 

 8-16, 1909 [A. H. Clark, 1912] (1, U.S.N.M., 35302). 



Bengal Fisheries steamer Golden Crown; off Gopalpore; 46-51 meters; September 

 23-27, 1909 [A. H. Clark, 1912] (2, U.S.N.M., 35304; I. M.). 



Ceylon Pearl Oyster Fisheries station LVII; Gulf of Manaar; outside Dutch 

 Moderagam Paar; 21-66 meters; bottom, orbitolites sand, nullipores, and dead corals 

 [Chadwick, 1904; A. H. Clark, 1912]. 



Ceylon Pearl Oyster Fisheries station LIII; Gulf of Manaar; 10-12 miles north 

 of Cheval Paar, and about 12 miles due west of Vankali (or Bangalli) Church; 14-16 

 meters; muddy sand, with some dead shells [Chadwick, 1904; A. H. Clark, 1912]. 



Ceylon [H. L. Clark, 1915] (1, Colombo, Ceylon, Mus.). 



Geographical range. From the Ganjam coast of India southward to Ceylon. 



Bathymetrical range. From 16 (?14) to 46 (?66) meters; the average of five 

 records is 37 meters. 



History. The first mention of this species was by Herbert Clifton Chadwick, 

 who recorded and gave notes upon specimens identified as Antedon bella from station 

 LIII and LVII of the Pearl Oyster Fisheries investigations at Ceylon carried on in 

 1902 under the direction of Prof, (later Sir) William A. Herdman. 



Under the name of Cenometra herdmani this species was briefly described by me 

 in 1909, the description being based on specimens collected by the Bengal Fisheries 

 steamer Golden Crown on the Ganjam coast of the Madras Presidency in 12 fathoms. 

 In my memoir on the crinoids of the Indian Ocean published in 1912 I repeated the 

 original description of the species, and recorded four specimens from the type locality 

 and another from the Ganjam coast in 24-30 fathoms. I gave a somewhat schematic 

 figure of the type specimen, in lateral view, and also figured a cirrus in lateral and 

 dorsal view, for comparison with corresponding figures of a cirrus of C. insueta (= bella) . 

 Unfortunately the legends on the figures of the cirri were exchanged, undoubtedly 

 through an oversight, so that the figures labeled Cenometra insueta in reality represent 

 a cirrus of C. herdmani and vice versa. In 1915 Dr. H. L. Clark recorded a specimen 

 from Ceylon and poited out the exchange of legends on my figures of cirri published 

 in 1912.
