Bougainville Island, and Tonga. I said that the specimens recorded agree well with a 

 specimen collected by the German steamer Gazelle at Bougainville Island and identi- 

 fied by P. H. Carpenter, and further that they were compared directly with Professor 

 Muller's types, which are in the Berlin Museum. The specimens referred to as 

 Miiller's types are those from the Red Sea collected by Hemprich and Ehrenberg. 

 The actual type of palmata, however, is the specimen brought by Dr. D. F. Eschricht 

 from "Indien." I listed D. klunzingeri, with the localities Koseir and Ras-el-Millan. 



In the revision of the family Mariametridae published in 1913, 1 referred to the new 

 genus Lamprometra the nominal species klunzingeri, leucomelas, palmata, and scita. 



In a paper on the crinoids of the British Museum published by me in 1913, speci- 

 mens of Lamprometra palmata were recorded from the Red Sea and from Muscat, and 

 notes on them were given. It was stated that Carpenter's record of this species from 

 Ceylon was based upon an example of L. protectus (= palmata) and that L. palmata 

 (klunzingeri} does not occur further eastward than Arabia. 



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

 I included palmata in my key to the species of the genus Lamprometra, including as 

 synonyms Comatula leucomelas, C. scita, and Antedon klunzingeri and giving as the 

 range the Red Sea and eastward to Muscat. 



In 1926 Dr. Th. Mortensen recorded five specimens that had been collected by the 

 Cambridge Expedition to the Suez Canal, 1924, and at the same tune H. Munro Fox 

 published a note on the color in life and the solubility of the pigment in fresh water. 



In 1929, in a paper on a collection of crinoids in the British Museum, I recorded as 

 ILamprometra klunzingeri a small specimen from Zanzibar. Under the heading 

 Lamprometra palmata I pointed out that the present species must be known as L. 

 klunzingeri (see page 516). 



In 1932 I recorded a specimen from Abu Zanima in the collection of the Indian 

 Museum, Calcutta.
