A MONOGRAPH OF THE EXISTING CRINOIDS 325 



In my monograph on the crinoids of the Indian Ocean published in 1912 I recorded 

 and gave notes on specimens identified as Heterometra bengalensis, which had been 

 collected by the Royal Indian Marine Surveying steamer Investigator south of Ceylon 

 and in the Andaman Islands. These specimens really represent H. reynaudi. In the 

 previously known localities given for this species, Queensland and Holothuria Bank 

 refer to Zygometra punctata, and Philippines refers to H. parilis. In an appendix 

 to this monograph additional specimens of H. bengalensis were recorded from off 

 Gopalpore in 25-28 and 30-38 fathoms, and from "?India." These specimens all 

 represent H. reynaudi. 



In a supplement to my memoir on the crinoids of southwestern Australia, published 

 in 1913, I transferred the Australian records for H. bengalensis to Zygometra punctata. 



In 1915 Dr. Hubert Lyman Clark listed this species from Ceylon, referring to my 

 memoir on the crinoids of the Indian Ocean (1912). 



In the report on the unstalked crinoids of the Siboga expedition published in 1918, 

 I inserted H. bengalensis in the key to the species of Heterometra and assigned the follow- 

 ing characters to it — brachials longer [than those of H. aspera] with more oblique ends 

 which overlap only very slightly, if at all; 11-15 arms. These characters were taken 

 from small specimens of H. reynaudi which were misidentified as bengalensis. The 

 range is said to be Ceylon and the eastern coast of India. Chadwick's specimens are 

 the only ones known from Ceylon ; all the others recorded from Ceylon, and all those 

 recorded from the eastern coast of India are in reality H. reynaudi. 



Heterometra aspera, described by me in 1909 from specimens collected at Singapore 

 by the Danish consul at that port, Svend Gad, was admitted as a valid species in the 

 memoirs on the crinoids of the Indian Ocean (1912) and on the Siboga collection (1918) 

 and was again recorded from Singapore in 1929; it ssems not to differ in any tangible 

 features from H. bengalensis.
