Type. Cut. No. 25650, U.S.N.M., from station 4969. 



The smallest of these specimens is rather less than 4 mm. across 

 the disk, but the specific characters are all well shown, except that 

 the radial shields are distally in contact. There is no species of 

 Ophiomitra now known with which this species is likely to be confused.
