 distant ribs bluntly spinose at the angle, with two tubercles

495. edentulus (f. 608, 609), Swcvmson. — There is now no 

 doubt of this shell belonging to the Mitra tribe; and the 

 only reason for not giving it a place in the genus is the 

 absence of columellar plaits. Otherwise, it should head the 

 section IX, (species 224 to 234), formed for Mitra dibajilu- 

 form/is and others.
