Mangelia darnleyensis Tryon, Man. Conch., vi., 1884, p. 256, pl. i., fig. 73. 
One of the original Darnley Island specimens is here figured. The 
species has the usual contour of Psewdorhaphitoma, but differs by the 
absence of fine grained spirals. This, with P. ditylota, fortilirata, and 
styracina, are aberrant members of this genus whose classification requires 
further attention.
