APPENDIX. 
Bibliography. 
An extensive bibliography of Himalayan literature published before the year 
1 Syi, has been given by Mr. Griesbach in his memoir on the Geology of the 
Central Himalayas (Memoirs of the Geological Survey of India, XXIII, 
pages 3 — 9), and a further list of works dealing with the North-VVest Himalayas 
and neighbouring areas will be found in Mr. Lydekker's "Geology of Kashmir" 
(Memoirs of the Geological Survey of India, XXII). Since the appearance of 
those Memoirs, a considerable amount of literature has been published on the 
subject of the palseontoiogy and stratigraphical geology of the Himalayas, and 
since this has a more or less direct bearing on the subject of the present 
memoir, it has been included in the following list of papers relating to Spiti 
and adjacent areas : —
