I have seen but one specimen of this species, and that 
forms part of the collection of the Earl of Derby, after 
whom I have taken the liberty of naming it. In my notes 
(made some years ago) I omitted to notice the sex, and 
cannot therefore state whether it possessed a pouch. Its 
habitat is unknown.
