ACANTHOGORGIA ARMATA Verrill. 

 Acantlwgorgia armata Vereill, Amer. Journ. Sci., XVI, 1878, p. 376. 



It appears to me to be likely that the Acanthogorgia spinosa of 

 Hiles" is a synonym of this species. The specimens in the Ha- 

 waiian collection vary considerably among themselves. 



Distribution. — Between Molokai and Oahu : Station 4107, 350-355 

 fathoms (Cat. No. 22556, U.S.N.M.). 



Off Bird Island: Station 4156, 286-568 fathoms (Cat. No. 25381, 

 U.S,N.M.). 



Vicinity of Niihaii Island: Station 4179, 378-426 fathoms (Cat. 

 No. 22557, U.S.N.M.). 



The original description was based on specimens taken from off the 

 New England coast, from depths of 304 to 524 fathoms. 



Genus PARAMURICEA Kolliker (emended by Verrill). 



Bases of contracted tentacles bearing spicules arranged en chevron, 

 forming an eight-rayed pseudo-operculum. Spicules of calyx walls 

 forming eight longitudinal bands. 



PARAMURICEA .^QUATORIALIS Wright and Studer. 



Paramuricea cequatorialis Weight aud Studee, Report on the Alcyonaria 

 collected by H. M. S. Challenger during the years 1873-1876, 1889, 

 p. 100. 



A specimen from Station 3859 (Cat. No. 25366, U.S.N.M.) agrees 

 with the original description and figures except that the spicules are 

 not so decidedly curved in our specimen, and do not show such de- 

 cided " stachenplatten." The calyces are exceedingly varied in form, 

 from a truncated cone to a short cylinder. 



The figures in the Challenger report do not agree with the descrip- 

 tion in the text as to the proportion of height to diameter of the 

 polyps. 



The type speciinens were taken by the Challenger near St, Pauls 

 Eock, South Atlantic, from a depth of 80 fathoms. 



PARAMURICEA HAWAIIENSIS, new species. 



Plate XLIV, fig. 1 ; plate XLVIII, fig. 3. 



Colony large, robust, flabellate in outline, incomplete, 200 mm. in 

 height. Main stem about 8 mm. in diameter, irregularly bent, giv- 

 ing off irregularly spaced lateral branches which resemble the main 

 stem; branches showing a tendency to branch on one side only, but 

 in some cases the distal branchlets are alternate ; branch terminations 

 abruptly enlarged and usually bearing a group of two to four later- 

 ally placed polyps.
