Affinity. The sternum in this genus, as well as in the next, being furnished with an 

 ensiform process, evidently points out an affinity between them. The trachea, however, differs most 

 materially, and the elongated tail is unlike any other genus of the family: still, that this is its true 

 place no doubt can remain, the ribs projecting far backward over the abdomen, and the hind toe 

 being largely lobated.
