preceding page) he was not sure that the latter was not identical with [Neocomatella] 

 pulchella. 



Under the name of Actinometra pulchella Hartlaub in 1891 recorded a specimen 

 of maculata from Ruk in the Carolines which he found in the Hamburg Museum, 

 giving a detailed description of it; and under the name of maculata he recorded 

 another in the Gottingen Museum from Mortlock Island in the same group. 



Prof. F. Jeffrey Bell in 1898 recorded this species (as Actinometra, sp.) from 

 Rotuma; in 1902 he listed it from the Maldive Islands, and in 1909 he noted it (as 

 Actinometra multiradiata) from Salomon and Coin Peros. 



In 1909 I published a detailed description of the specimen from Bowen labeled 

 Actinometra jusca in the Copenhagen Museum, and definitely identified it with Car- 

 penter's Actinometra maculata. 



As a result of a visit to the British Museum in 1910 I found that Bell's ^diwo- 

 metra multiradiata from the southwestern Indian Ocean was in reality this species, a 

 fact which I stated in a paper on the crinoids of the African coasts published in 1911. 

 In my memoir on the crinoids of Australia published in the same year I gave the dis- 

 tribution of this species as corrected from my studies on the material in the British 

 Museum and remarked that the type specimen in London resembled very closelj^ the 

 example from Bowen in the Copenhagen Museum. In the same year also I recorded 

 it from western Java and from New Caledonia. 



In 1912 I stated that Hartlaub's Actinometra pulchella from Ruk, which I had 

 examined in the Hamburg Museum, represented the same species as Carpenter's 

 Actinometra maculata. 



In my memoir on the crinoids of the Indian Ocean (1912) I identified Carpenter's 

 Actinometra pulchella from Challenger station 192 near the Ki Islands as maculata. It 

 is, however, Palaeocomatella difficilis. Evidently I had at the time confused it with 

 Hartlaub's Actinometra pulchella from Ruk. In the same memoir I identified BeU's 

 Actinometra simplex from the Macclesfield Bank as maculata; it is in reality, however, 

 stelligera. 



In a paper on the comatidids in the British Museum published in 1913 Bell's 

 Actinometra simplex and A. maculata from the Macclesfield Bank were placed in the 

 synonymy of stelligera, where they belong. 



The 4 specimens referable to maculata which I saw in tliis collection were Car- 

 penter's type and 3 which had been recorded by BeU in 1898, 1902, and 1909 as given 

 above. 



Dr. August Reichensperger in 1913 recorded and described in detail a specimen 

 from Ceylon. In 1915 Dr. Hubert Lyman Clark recorded this form as very common 

 at Mer in Torres Straits, and gave a detailed account of its habits and reactions. 

 (See vol. 1, pt. 2, pp. 602-604.) 



In 1918 I recorded and described the specimens secured by the Siboga expedition, 

 and in 1921 Dr. H. L. Clark published an exhaustive account of this species based 

 primarily on his experience with it in Torres Straits, accompanied with a colored 

 figure. 



Dr. Torsten Gisl^n in 1922 described in detail certain specimens in Bock's col- 

 lection from the Bonin Islands which he assigned to this form.
