A MONOGRAPH OF THE EXISTING CRINOIDS 443 



not especially noticeable. The range of monacantlw, was given as from the Andaman 

 Islands to Singapore, the Philippines, the Malay Archipelago, New Caledonia, Fiji, 

 and the Tonga and Caroline Islands; the range of indica was said to be from Mada- 

 gascar, the Seychelles, and Kodriguez to Ceylon and southern India, also the Lesser 

 Sunda Islands and northern Australia. Dr. H. L. Clark's Lamprometra callipecha 

 was placed in the synonymy of Lamprometra protectus (=palmata). 



In his memoir on the echinoderms of Torres Strait published in 1921 Dr. H. L. 

 Clark noted that I had referred the specimen from Mer that he had recorded as 

 monacantha to indica, but since examining the specimen I had become satisfied that 

 it really is monacantha (=protectus). Under Stephanometra callipecha he said that 

 the reexamination of the type specimen of this species, resulting from my assigning 

 it to the synonymy of Lamprometra protecta (=palmata), had led him to beheve that 

 it should be regarded as a Stephanometra rather than as a Lamprometra, and that it is 

 possibly identical with S. indica. He added that after examining the type specimen 

 I had decided that it is indica.
