342 RECENT OPHIURANS. 



believed they were, comparison with the large amount of material available here 

 would reveal their true relationship, since they were quite unlike any New 

 Zealand brittle-stars with which he was familiar. It is interesting to find that 

 their nearest relatives seem to be the two species of Ophiozona, a genus which 

 in the original, and recently restricted, sense is known only from the Caribbean 

 and Panamic regions.

Ophiolepis. 



iVItjLLER and Troschel, 1842, Syst. Ast., p. 83, 89. 



Type-species: Ophiura annulosa Blainville, 1834. Man. d'Act., pi. 24. Type designated by 

 Lyman, 1865. Since 0. annulosa Bl. is not 0. annulosa Lamarck, 1816, the name ought never to have 

 been used. MiiUer and Troschel, Liitken, and Lyman all recognized the fact that Blainville's proposed 

 name was a homonym but curiously enough none of them suggested a substitute. So that down to the 

 present time we have an Ophiura annulosa serving as the type of OphiomastLx, while another Ophiura 

 annvlosa is the type of Ophiolepis. A new name for Blainville's species has therefore been suggested 

 recently. (See p. 343).
