58 McMahon 8f Hudleston — Fossils from the Hindu Khoosh. 



obtained a large series of fossils, whioh Kayser regarded as Devonian, 

 In vol. iv of Eichthofen's China, Herr Kayser recognizes 14 species 

 as previously known and 14: as new — all of Devonian age/ So 

 much, then, for Devonian beds in China. 



Proceeding westwards, we next find traces of a Devonian fauna 

 in the Shan states of Burmah. The following is from a report 

 of the Geological Survey of India (March 31, 1901) : " The 

 occurrence of Devonian, which had been inferred by Mr. P. N. Datta, 

 has been confirmed by Mr. La Touche, who found Calceola sandalina" ^ 

 It is a far cry from northern Burmah to Chitral ; nevertheless, over 

 a range of 2,000 miles from hard by the Pacific near Canton to 

 the very centre of the Hindu Khoosh there are four or five points 

 ■where a Devonian fauna has been proved to exist in regions not 

 particularly accessible to the palaeontologist. Our thanks are 

 therefore due to General McMahon and his able coadjutors in 

 Chitral for having brought this interesting series of fossils to light.
