inversus Oka, 1928, from the western Pacific (13°26' N. X 145°40' E., 

 3,500 m.) is unique in the situation of the atrial aperture on the 

 ventral side and in having an unusually large branchial aperture. 

 C. murrayi Herdman, C. gigas Sluiter, and 0. thysanotus Sluiter each 

 have a single gonad on each side; the last one especially cannot be 

 confused with others because of its peculiar external appearance. 

 G. moseleyi Herdman from a GJiallenger station in the Central Pacific, 

 not far from the locality of the present specimen, and C. annulatus 

 Sluiter from the Slboga area are devoid of the row of distinct papillae
