Locality. Albatross station 5601; Gulf of Tomini, Celebes; 

 Limbe Island (NE.) bearing N., 38.36 kilometers (20.7 miles) dis- 

 tant (lat. 1 13' 10" N., long. 125 17' 05" E.) ; 1,399 meters (765 

 fathoms) ; November 13, 1909; S., Glob., Ptr. 



A small specimen (Cat. No. 41176, U.S.N.M.). 



Notes. The diameter of the disk does not exceed 5 mm. 



The Challenger discovered this species among the Philippine 

 Islands at a depth of 1,920 meters (1,050 fathoms), and the Siboga 

 met with it at neighboring stations between 1,158 and 2,053 meters 

 (635 to 1,122 fathoms). The Investigator also dredged it at Minicoy 

 in 2,195 meters (1,200 fathoms).

Locality. Albatross station 5639; Molucca Sea; Cape Pamali 

 (Wowoni Island) (N.) bearing S. 77 W., 43.44 kilometers (27 

 miles) distant (lat. 3 54' 50" S., long. 123 27' 20" E.) ; 2,853 meters 

 (1,560 fathoms) ; December 13, 1909; gy. M. 



Two specimens (Cat. No. 41152, U.S.N.M.). 



Notes. The diameter of the disk is between 11 mm. and 12 mm. 

 In one of the two specimens the large marginal plate which delimits 

 the vertical sides of the disk in the interradial spaces is replaced by 

 two contiguous plates; in the other, this modification occurs in four 

 of these spaces, so that only a single interradius shows the usual ar- 

 rangement. 



I discussed the identity of this species with O. variabilis as well as 

 its geographical distribution in my memoir of 1914, cited above.
