Plate 5, figs. 5, 6 ; plate 92, fig. 1. 



Ophiomyxa bengal emis Kcehler, '96, p. 363, pi. 9, figs. 70, 71 ; '99, p. 69, pi. 

 12, figs. 91, 92.— H. L. Clark, '15, p. 168. 



Locality. — Albatross station 5292; China Sea, in the vicinity of 

 southern Luzon ; Escarceo Light bearing N. 36° W. 6.02 kilometers 

 (3.25 miles) distant (lat. 13° 28' 45" N., long. 121° 01' 12" E.) ; 296 

 meters (162 fathoms) ; July 23, 1908; fne. bk. S. 



Eight specimens (Cat. Nos. E.225, E.226, U.S.N.M.). 



Notes. — All these specimens agree well with the type series, which 

 was dredged by the Investigator among the Andaman Islands at 

 depths varying between 457 and 1,962 meters (250 and 1,073 

 fathoms). I give here two photographs of one of the Albatross 

 specimens, which show better than my figures published in 1896 and 

 1899 the habitus of this species. I also include some photographs of 

 arm spines from different portions of the arms.
