The only specimens of this very remarkable species yet obtained 

 are the type, a skin in bad condition in the collection of the Indian 

 Museum, Calcutta, and an adult male (the type of C. hernsteinii, 

 Peters) preserved in alcohol in the Leyden Museum. I have 

 examined both specimens, and have no hesitation in referring them 

 to the same species.
