[NOTE. 



My attention has been called to a paper by W. H. Dall, " On some Hydro- 

 corallinaB from Alaska and California," in the Proc. Biol. Soc. Washington, vol. ii. 

 1885, p. 111. 



In this paper three new species o( Jllopora are described from the Aleutian and 

 Shumagin islands, namelj', A. verrillii, A. moselei/i, and A. papillosa. 



They differ in some respects from the specimen I have identified as Stglaster 

 {A.) norvegicus from the Swiftsure shoal off Vancouver Island, but I do not 

 consider, without reference to the type specimens, that these differences are 

 sufficient to justifj" a specific distinction from the older species. 



In this paper there is also a record of a specimen identified as Calligorgia 

 compressa Verrill from the Aleutian islands, but as there is no figure or description 

 of it, comparison with the specimen described by me as Caligorgia fraseri cannot 

 be made. The type specimen of T\ compressa is {Jide Versluys, p. 81) only a 

 naked axis without polyps or spicules.
