 Senegambia, whence came the four specimens in the British Museum. Dr. de Eoche-

 Melacoree, Sedhiou, and Bathurst; the native name is stated to be " N'Jargaigne.'" 



The description is taken from the British-Museum ' Catalogue.' The figure is drawn 

 from a specimen in Capt. Shelley's collection from Senegambia.
