80 BULLETIX 83, UNITED STATES NATIONAL MUSEUM 



The figures of the cirrus and of the earlier brachials with Pi and P 2 given by 

 Professor Gislen are typical of Parametra orion, and there is nothing in the descriptions 

 of the specimens to indicate that his specimens do not belong to this species. 



The specimen from near Nagasaki in 311 meters has 14 arms 130 mm. long, and 

 XV cirri 20 mm. long arranged in a single marginal row. 



The specimen from south of the Goto Islands in 223 meters has 15 arms 125 mm. 

 long and the cirri XVIII, 23-24, from 21 to 23 mm. long. 



It was from one of these two specimens that Dr. Mortensen secured the eggs, 

 which he found to be 0.15 mm. in diameter. 



In this species the arms vary from 10 to 18 in number and reach a length of 140 mm. 

 In fully developed individuals the cirrus sockets are arranged in 15 columns on the 

 centrodorsal, but in small ones there are commonly only 10 columns.
