Blanford writes (J. A. S. B. 1865, p. 95): " A small variety of 

 A. erassilahris, Bs., occurs in Arakan, and another form perhaps 

 distinct, but closely allied, was found in tlie Shan Hills near Ava." 



Specimens of the first I found unnamed in Henry Blanford's 

 collection collected by Mr. Raban of the Indian Civil Service. I 

 consider thera distinct and have named them G. rahani. Those 

 from the Shan Hills have come to light in Wm. Blanford's 

 collection (No. 261-06.2.2), five specimens. They are undoubtedly 

 distinct, and I have named the species O. feddeni after Mr. 

 Fedden of the Geological Survey of India, who collected largely in 

 that pai't of Burma.
