OPHITTRANS OF THE PHILIPPINE AND ADJACENT WATERS. 319 



Whether it refers to an Ophiocoma resembling 0. echinata, of which 

 the habitat is given is entirely erroneous, as Lyman suggested, or 

 whether it refers to an Ophiocomina nigra the occurrence of which 

 on the coasts of Sicily is now known, is the question. It appears 

 to me more difficult to admit this latter hypothesis, at least if Miiller 

 and Troschel's diagnosis be considered correct, since they attribute 

 to the specimen from Genoa only four arm spines. The re-examina- 

 tion of the type specimen in the Leyden Museum will alone remove 

 this uncertainty.

Notes. — A good description of this species was given by Loriol ('93, 

 p. 26) ; Walther has also published some interesting notes upon it ('85, 

 p. 371), and more recently Benham has described a specimen from 

 the Kermadec Islands ('11. p. 153).
