NO. 9 MARINE INVERTEBRATES, ALASKA — MacGINITIE 121 



tentacles, but on August 17, 1949, a large orange-brown specimen 

 was seen. Frequently a form with a whitish bell and delicate flesh- 

 colored tentacles was seen. This form, 4 to 12 inches in diameter, 

 was abundant on September 8, 1948, and common on September 15, 

 1949. Specimens of Cyanea species up to 20 inches in diameter were 

 taken through holes in the ice throughout the winter of 1949. Ephyra 

 and postephyra stages less than half an inch in diameter, with trans- 

 parent bell and lobes and very pale flesh-colored central parts, were 

 taken in August 1948 and from September to November 1949. 



A species of Chrysaora was seen frequently but never in such 

 abundance as the above two species. On November 19, 1949, several 

 specimens contained yellowish-brown eggs, some of which were 

 rotating and developing into active planulae. 



Two species of commensal phronimids, Hyperia medusarum and 

 Hyperoche medusarum, were found with Cyanea and Chrysaora. (See 

 "Amphipoda.") 



Class ANTHOZOA 



Subclass Alcyonaria 



One species of the octocoral Eunephthya rubiformis (Pallas) was 

 found. It was exceptionally abundant at Eluitkak Pass and was 

 dredged from 125 to 522 feet. Colonies up to 6 inches high were not 

 uncommon. Occasionally instead of colonies of the usual reddish color, 

 a pale-orange or a beautiful apricot-colored colony was taken. 



Subclass Zoantharia 

 Order ACTINIARIA 



Sea anemones were exceedingly abundant in some hauls, rare or 

 absent in others. The most plentiful species, Stomphia coccinea (O. F. 

 Miiller) was characterized by brick-red markings on a cream back- 

 ground, with tentacles about the color of the markings. Small speci- 

 mens do not show these markings so vividly. Adult specimens that 

 were a delicate peach color throughout were frequently taken, but 

 they may belong to another species. Specimens 65 mm. high and 

 with a basal diameter of 70 mm. were dredged. This species was taken 

 at Eluitkak Pass and at most of the rubble-bottom stations. In one 

 dredge haul from 130 feet (on September 15, 1948) there were 123 

 specimens, and hauls from several other stations brought up 50 or 

 more. 



One specimen of this species taken on October 14, 1949, at 175 feet
