^"i8.K^r'] PROCEEDIN(;S OF THE NATIONAL MIJSKUM. 187 



Tlio spcciiiKuis Nos, I'.V.i and 7.'55, obtaiiuMl in tlu' same (li'('(lgiiij>- as 

 N(). 731, are both small, an<l white or ])ale brown in color, tliecntiele 

 being only very slightly (leveloi)e<l. The base is only slightly eoneave 

 and seems to hav(^ been adherent. The ui)i)er i)art of the eolunni is 

 nmiked by twenty Ibnr longitn<linal ridges, whi(;h show more or less 

 distinct trae<'s of transverse grooves, dividing ea(!h ridge more or less 

 j)erfeetly into ;i series of tul)erch\s. I see no reason for sni)])Osing that 

 these ar<^ other than yonng individnals of the same s|>eeies as No. T.'U. 



In changing the name of this species I ha\c, followed the suggestion 

 made by I?rof. Iladdon ('SO), and have named it atter tlie distinguished 

 naturalist who tirst described it. Vcirill identilied it with the Actinia 

 nodosa of f'iibiicius, but the more re(;ent observations of Ila-ddon ('Sl>) 

 and Danielssen ('!)()) show that the two forms are quite distinct, and 

 the former has assigned Fabricius' form to the genus (Utoudractiniaiwo- 

 ])osed for it by Liitken ('<»0). Tliis being the cnse, it seems iidvisable, 

 for the av^oidanc<', of thc^ confusion whicli might ensue frcun two so 

 closely related forms [)ossessing the same sp(;(;itic name, to change the 

 name of Verrill's species.

[t is custonuiiy, whi'n ,\. foim originally described as a variety is ad- 

 van(;e(l totlie dignity of a si)ecies, to employ the varii^tal designation as 

 tlu' specilic nam«\ 1 hiiv«^ thought it well in tlu^ ])r<'seiit case to depart 

 from tliis precedent, since tlie specilic teini eoroiiata has aln'ady been 

 ai)plied to a form belonging to the genus ('hifoiioelis, which is nearly 

 related to Actiitauf/c. 



The s|)ecimens of Actinau<ic J'asii<i<(l<(^ obtained by the AUmtroHH from 

 the same locality as most of the si)ecimenH of ^. Verrillii, are in all re- 

 spe<'ts similar to those described by Verrill ('8.'i) from deej) water off 

 the St. (leorge's Hanks. 



The s])ecimens measure from .'».5 to 4.4'^'" in height, with a diam<!tei- 

 at the upper i)art of the column of from U to li.5"". 



The base is somewhat smaller than the column and, ai)])arently, is 

 adherent; one of the specimens clas])s the tube of a. l/i/alin(tria. in 

 none of tlui specnmeus is it deej)ly concave, inclosing mud or sand, as 

 is the case with A. Verrillii. Tiu^ limbus is smooth, and in nearly all 

 the si)ecinu'ns is destitute of cutich'and is rather thin, allowing the in- 

 sertions of the mesenteries to show through. 



The eolumn is cylindrical (PI. xxxr. Fig. 93), gradually increasing in 

 dianieter towards the upi)er j)iiit, the capituliim being, however, com- 

 pletely infolded in all the specimens. The lower i>art of the c<jlumn is 

 covered with low Un<l snmll warts, arninged, more or less distinctly, iu
