OPHIOZONA NIVEA var. COMPTA Verrill. 

 Ophiozona nivea var. compta VERRILL (99a), p. 303. 



Off Havana, 1886. One specimen. 



Diameter of disk 9.5 mm.; one arm only is entire, its length being about 30 mm. 

 The radial shields are separated on their whole length. 



This specimen can be referred to the variety distinguished by Verrill, but if 

 we consider how easily this species varies, a fact owned by Verrill himself, one may 

 be in doubt as to the usefulness of introducing a new variety based on the radial 

 shields being more or less spread, while there are other plates, such as the mouth 

 shields for instance, which are likely to vary quite notably in shape and in their 

 relations with one another. 



0. nivea var. compta has been met with off Havana, between 110 and 263 

 fathoms. The typical species has been taken in various localities of the Caribbean 

 Sea by the Hassler and the Blake, between 56 and 424 fathoms.
