This was stated in a book “Faunal Diversity of Biogeographic Zones of India: North-East” brought out by Zoological Survey of India and released yesterday at Shillong.
Speaking at the meeting, Dr. Kailash Chandra, Director of ZSI, spoke of the hard work put in during the compilation of this book, which is a comprehensive and exhaustive account of the faunistic resources of the North-East Biogeographic Zone.
