 pi. 8, fig. 127,a-c: "Only one specimen examined"; 1862, Otia

Clench and Turner, 1948, Occ. Pap. Moll., vol. 1, no. 13, p. 205, 

 pi. 23, fig. 5, inadvertently selected a lectotype (MCZ 178662) for 

 this species since the figured holotype was not available to them. 

 Their specimen was received from the Smithsonian Institution, 

 but it must have been subsequently identified because Gould based 

 the original description on a single specimen.
