170 BULLETIN 82, UNITED STATES NATIONAL MUSEUM 



Notes. — One of the specimens from Siboga station 318 is a magnificent example 

 of the species. It has 110 arms which are 140 mm. long. No fully developed cirri 

 are preserved, but from the young cirri present it appears undoubtedly to be referable 

 to this form instead of to C. sentosa which, except for the cirri, it exactly resembles. 



The other two specimens are smaller, with 33 and 35 arms and cirri 35 mm. long 

 composed of 28-36 segments. They seem to belong to C. gracilicirra rather than to 

 C. tenuicirra, although as yet they have not acquired all of the characters of that 

 form. 



The smaller specimens from Siboga station 318 are pecuUar in having on the 

 outer cirrus segments two dorsal spines, a proximal and a distal. 



The single individual from Siboga station 320 has been chosen as the type of 

 the species. The cirri are XVII, 27-35 (usually nearer the latter), 33 mm. long. 

 The longest proximal cirrus segments are twice as long as broad, and are slightly 

 constricted centrally with swollen ends. The shorter distal segments are about as 

 long as broad. The tenth or eleventh is a transition segment. There are 51 arms 

 100 mm. long. 



Localities.- — Siboga station 318; Java Sea, east of Madoera, north of the eastern 

 end of Java (lat. 6° 36' 30" S., long. 114° 55' 30" E.); 88 meters; fine yellowish gray 

 mud; February 22, 1900 [A. H. Clark, 1918] (3, U.S.N.M., E. 456 ; Amsterdam Mus.). 



Siboga station 320; Java Sea, northeast of Madoera (lat. 6° 05' 00" S., long. 

 114° 07' 00" E.); 82 meters; fine gray mud; February 23, 1900 [A. H. Clark, 1912, 

 1918] (1, Amsterdam Mus.). PI. 9, fig. 27. 



Remarks. — This species is only known from the original specimens collected by 

 the Siboga in 1900.
