1. Actinometra brachiolata, Lam., sp. I refer to this type the form described by 

 Muller ' under the MS. name Comatula rosea, Mus. Vienna. He noted its close relation- 

 ship to and possible identity with Lamarck's type, and an examination of both has con- 

 vinced me that they are really identical. 



2. Actinometra pectinata, Linn., sp. I have come to the conclusion that Actinometra 

 affinis, Lutken, MS., which appeared in my former list, 2 is identical with the form which 

 Retzius referred to the Asterias pectinata of Linnaaus. The Alecto purpurea of Muller 3 

 is probably a young form of the same type. 



3. Actinometra Solaris, Lam., sp. The type for which Bell gave a formula under 

 the name of Actinometra albonotata* is now regarded by him as a variety of Actino- 

 metra Solaris. 6 The following specific names have also been applied to this type at 

 different times — hamata, imperialis, intermedia, robusta, and strota. (See p. 288.) 



4. Actinometra paucicirra, Bell. The form described by Bell under this name 8 turns 

 out to be only the premature stage of the type to which I referred in my Preliminary 

 Report as Actinometra jukesi? But it has not yet been formally described, and Bell's 

 name therefore must take precedence. 



5. Actinometra pulchella, Pourt., sp. This is the Antedon ptdchella. of Pourtales, 

 another form of which was also described by him as an Antedon alata. s
