40 PROCEEDINGS OF THE NATIONAL MUSEUM. vol.43. 



Color: The polyps are reddish-brown and the rachis light yellow. 

 The end bulb is reddish-brown. 



Localities.— Station 4768; lat. 54° 20' 30" N.; long. 179° 09' 30" E.; 

 764 fathoms. Station 4792; Cape Monati, Bering Island, N. 50° W., 

 8.2 miles; 72 fathoms. Station 4985; Kamoi Misaki Light, N. 17° E., 

 15,2 miles; 224 fathoms. The specimen described came from this 

 station. Station 5031; lat. 44° 04' 00" N.; long. 145° 32' 00" E.; 

 86 fathoms. 



Specimens from station 4792 had the tentacles expanded, and their 

 dorsal surfaces were marked by clear-cut white lines of silvery spicules. 



General distribution. — The type-locahty is off the Californian coast. 



BALTICINA CALIFORNICA (Moroff). 



Pavonaria californica Moroff, Studien iiber Octocorallien, Zoologische Jahr- 

 bucher, Abth. Syst. Geogr. Biol. Thiere, ser. 5, vol. 17, Heft 3, 1902, p. 393. 



Length 97.5 cm., stem 32 cm. There are 115 polyp rows, polyps 

 3 to 5 in each row. There are spicules in the two teeth on the margin 

 of each calyx. The tentacles are without spicules, the characteristic 

 feature of this species. 



The polyps are reddish-brown. 



Localities. — Station 4984; Benkei Mizaki Light, S. 3° W., 15 miles; 

 248-224 fathoms. Station 4986; Benkei Mizaki Light, N. 35° E., 

 15 miles; 172 fathoms. 



General distribution.- — The type-specimens were presumably from 

 the Californian coast, although this fact is not noted in the original 

 description. 



This species may be the same as the last, but the absence of ten- 

 tacular spicules is a character which, if constant, would be a good 

 specific character. Both specimens in this collection have parasitic 

 or symbiotic astrophytons attached to them. 



Genus HALIPTERIS Kolliker, modified by Jiingersen.* 



Calyces with 2 to 4 teeth; zooids lateral. 



HALIPTERIS CHRISTII (Koren and Danielssen). 



Virgularia christii Koren and Danielssen, Nyt Magazin for Naturvidenskaberne, 



vol. 5, 1848, p. 269. 

 Halipteris christii Kolliker, Anatomiscb-Systematische Bescbreibung der Alcyo- 

 naria, I, Die Pennatuliden, 1872, p. 249. 



Length of colony 12 cm. Stem 3.2 cm., very slender, with no 

 evident swelling, and a very slender and inconspicuous end bulb. 

 The calyces are arranged in a single zigzag row, or double row, 



1 This genus is here placed in the family Virgularidas, instead of the Protoptilidse, on account of the argu- 

 ment presented by Jiingersen in Danish Ingolf Expedition, vol. 5, 1904, p. 45. This writer, however, 

 Institutes the family Pavonaridse, in which he includes Halipteris. He finds that the genus Stichoptilum 

 of Grieg represents merely the young stages of Halipteris.
