Ophiomoeris spinosa KCEHLEB ('04), p. 17, pi. 4, figs. 1-3. H. L. CLABK 

 ('15), p. 190. 



Locality. Albatross station, 5577; north of Tawi Tawi; Mount 

 Dromedario bearing S. 9 W., 20.20 kilometers (10.9 miles) distant 

 (lat. 5 20' 36" N., long. 119 58' 51" E.) ; 439 meters (240 fathoms) ; 

 September 23, 1909 ; crs. S. 



One specimen (Cat. No. 41006, U.S.N.M.). 



Notes. This specimen is slightly smaller than those dredged by 

 the Siboga; one of the arms is broken off at the base. 



The Siboga collected Ophiomoeris spinosa in latitude 5 N.-5 S., 

 and longitude 119-132 E., at depths varying from 104 to 1901 

 meters (57 to 1,040 fathoms). 



OPHIOMOERIS TENERA Kcehler. 



Ophioceramis tenera K<EHLER ('96), p. 317, pi. 6, figs. 30, 31; ('99), p. 33, pi. 



5, figs. 42, 43. 

 Ophiomoeris tenera KCEHLER ('04), p. 17. H. L. CLARK ('15), p. 190. 



Locality. Albatross station 5423, Jolo Sea, Cagayan Island (S.) 

 bearing S. 11 E., 8.89 kilometers (4.8 miles) distant (lat. 9 38' 30" 

 N.,long. 121 11' 00" E.) ; 929 meters (508 fathoms) ; March 31, 1909; 

 gy. M., co. S. 



Two small specimens (Cat. No. 41005, U.S.N.M.). 



Notes. These specimens are smaller than the type of the species, 

 but agree very well with it. 



Ophiomoeris tenera was discovered by the Investigator among the 

 Andaman and Laccadive Islands in depths between 484 to 1,160 

 meters (265 and 636 fathoms). 



OPHIOGYPTIS NODOSA Kcehler. 



Plate 6, figs. 5, 6. 



Ophiogyptis noaosa KCEHLER ('05), p. 121, pi. 12, figs. 11-14. H. L. CLARK 

 ('15), p. 193. 



Locality. Albatross station 5414; between Cebu and Bohol; Lauis 

 Point Light bearing N. 67 W., 17.61 kilometers (9.5 miles) distant 

 (lat. 10 10' 40" N., long. 124 02' 45" E.) ; March 24, 1909. 



One specimen (Cat. No. 41004, U.S.N.M.). 



Notes. The specimen is very small, the diameter of the disk being 

 only 2.5 mm. ; three of the arms are broken off close to the disk and 

 the two others are preserved for only a portion of their length. 



I described O. nodosa from several specimens collected by the 

 Siboga among the Sunda Islands at depths between 73 and 113 meters 

 (40 and 72 fathoms) in which the diameter of the disk varied between 

 3 and 5 mm. The Albatross specimen has almost the same dimensions
