NO. 102:?. DESCRIPTIONf^ OF PACIFTC ALOYONARIA—NUTTINO. 85 



Spicules: These are mainly small triradiatc and quadriradiato 

 forms and butterfly shapes. Irregularly branched and radiate forms, 

 with a few true spindles and a few clubs and daggers are found. 



Color: A rather lively yellowish-brown. 



Locality. — Station 4936; Sata Misaki Light, N. 21° E., 5.7 miles; 

 103 fathoms. 



Type-specimen.— Csit. No. 30098, U.S.N.M. 



Another specimen from the same station is characterized by much 

 more prominent spicules, those on the calyx walls forming evident 

 points. 



Genus ELASMOGORGIA Wright and Studer (emended). 



Colony simple or sparingly branched, very slender and flexible; 

 calyces very low and distant verrucse; spicules medium-sized spindle^, 

 not attaining the size of those in Muricella or Acis. 



ELASMOGORGIA FILIFORMIS Wright and Studer. 



Elasmogorgia fdifonnis Wright and Studer, Challenger Reports, the Alcyonaria, 

 1SS9, p. 133. 



Colony an unbranched stem, very slender and flexible, 47 cm. long, 

 diameter 1 mm. 



Although in places the calyces tend to be lateral and alternate, they 

 are really on all sides of the stem, somewhat distant but irregularly 

 spaced, being about 3 mm. apart. 



The individual calyces are low conical verrucse, about 0.7 mm. high 

 and with a basal diameter of about 1.8 mm., although this is hard to 

 estimate because the calyx walls slope so insensibly into the general 

 surface of the coenenchyma. The calyx walls arc filled with small 

 short spindles arranged transversely on lower parts and a few small 

 ones vertically placed around the margin, their ends forming an 

 inconspicuous circlet of points. The polyps are usually completely 

 retracted ami almost entirely concealed by the indrawn margins. 

 Some of them, however, rest with the collaret on the margin. The 

 collaret is well marked, consisting of two or more circular rows of 

 spindles. The operculum is strong, each flap consisting of tliree 

 spindles forming an acute-angled triangle, reenforced by others l^'ing 

 parallel to these, or disposed longitudinally on the distal parts of the 

 tentacles. 



The coenenchyma is flllcd with a compact layer of short stout 

 spindles lying lengthwise of the stem. 



Spicules: These are all rather small spindles for this family, tlieir 

 surface covered with cons])icuous verrucae. 



Color: TJie colony is rather dark brown; axis almost black.
