The li?t which now follows gives, in alphabetical order, the more 

 important of the specific titles which have been applied to species 

 previously named. The list has been here limited to those forms 

 which have been regarded by competent naturalists as members of 

 the genus, as defined and limited by Miiller and Troscbel, or what 

 may, for brevity, be styled the Asteracanthion division of the Asterida. 



1 may, in passing, be allowed to beg leave to be excused from 

 entering into any defence of tlie use of the generic term Asterias. 

 I can add nothing to the summary of contending facts which have 

 been put out by the Rev. A. M. Norman'; and I willingly give in 

 my adhesion to the majority of his arguments. The labours of 

 synonymy are severe enough to justify me in refusing to go again 

 into a detailed examination of a subject which seems to me to 

 have been exhausted ^. 



To the left of some of the names there is placed the name of an 

 authority who has directed attention to the synonymy of the species 

 in question. 



II. List of the Principal Names which are regarded as 

 Synonyms. 



1. albulus, Stimpson, =^ Stichaster albulus. 



2. angulosa, O. F. M., = glacialis, O. F. M. 

 (Verrill.) 3. arenicola, Stimpson, = forbesi, Desor. 



(Liitken.) 4. atlantica, Verrill, = tenuispina, Lamk. 



5. aurantiaca, Meyen, = Stichaster aurantiacus. 



^ If the specimens collected by Dr. Cunningham have been correctly identified, 

 A. ruffispina must be very closely allied to A. antarctica.
