There is likewise a species of Hulothuria, on which I propose to 

 suspend my judgment.

4. ASTERIAS NEGLECTA. 



Asterias negieeta, Cell, Pioc. Zool. Soc, Lond., 1881, pp. 94 and 506. 



The name I gave tliis species had reference to its past ; it might 

 well be regarded as prophesying its future. For twenty years the 

 single specimen found by Dr. Cunningham in the Straits of Magellan 

 has been unnoticed and without a companion ; as a larger specimen 

 comes from Franklin Island we are led to suppose that the distribu- 

 tion of this southern species is circumpolar. 



5. Asterias Antarctica. 



Asteraeanthion antarcticum, Liitken, Vidensk. Meddel., 1856, p. 105. 

 Asterias antarctica, Perrier, Arch. Zool. Expe. IV. (1875), p. 315. 



This species does not appear to have been studied Ijy any other 

 naturalists than the two named above. I had begun a correspondence 

 with the late Dr. Liitken regarding our lately acquired specimens, 

 but the state of his health and his lamented death prevented my 

 having the advantage of his judgment. As Liitken's specimens 

 came from the Straits of Magellan, and the ' Southern Cross ' examples 

 from Cape Adare (28 fathoms), it may be supposed that the distribu- 

 tion of the species is circumpolar. 



6. Cycethra simplex. 



The following appears to be the synonymy of this species ; to 

 Professor Perrier belongs the credit of having been the first to
