The original specimens were from the Bay of .Monterey, 20 fathoms. 



In his discussion of this species, which he ascribes to the genus 

 Stylutuht, Yen-ill expresses a doubt as to its belonging to this genus 

 at all. The specimens collected by the Fisheries steamer Albatross 

 agree quite well with the original description of Virgularia gracilis 

 Gabb, and this, together with the fact that the locality is the same 

 and the species evidently abundant at moderate depths in the Bay 

 of Monterey, makes it quite likely that the species is correctly identi- 

 fied as Virgularia gracilis Gabb, which now goes into t lie genus 

 AcarUhopHlum. 



? ACANTHOPTILUM POURTALESII Kblliker. 



Acanthoptilum pourtalesii Kolliker, Anat. Syst. Bes. Alcyonarien, Pt. 1, Die 

 Pennatuliden, 1872, p. 231. 



A specimen, without label, agrees closely with Kolliker's descrip- 

 tion, except that the spicules of the stem are not "biscuit-shaped" 

 but of the usual rod-like type. 



A very young specimen, apparently of this species, from the collec- 

 tion of the University of California from San Diego Bay, shallow 

 water, has the leaves much more widely separated than the other. 



The original specimens described by Kolliker were secured off the 

 Florida reefs at depths of from 12 to 44 fathom--.
