 from that species, as from all other species of the group, by its coal- 

 black, scale-like indusia, ciliate with whitish hairs.

An interesting discovery, as the species was previously known 

 only from Guadeloupe. The specimen agrees exactly with the type. 

 It resembles some forms of D. pachyrachis included under Jenmani, 

 but it has a scaly stem, many pairs of reduced phinse, and the upper 

 surface pubescent.
