waters westwards into the great drainage system of the Indus, 
carrying with at its Bengali fauna. The upper springs of the Saras- 
wati, following the same law, have long since become those of 
what we now call the Satlej, and of the drainage channels of the 
plains of Kurukshetra, the greatest still turns westwards, and its 
overflow is absorbed in the Great Desert, or, if it gets into the sea 
at all, does so by the Indus drainage system. It must be remem- 
bered that, at the remote semi-historical age spoken of, the Satlej 
itself, and all the other rivers of that system, must have flowed far 
east of their present course. 
There is nothing new in the hypothesis advanced. Peter the 
Great’s Scotch surveyor found the Oxus flowing into the Caspian, 
which now flows into the Aral, though the old channel was redis- 
covered by the expeditions of Peter’s last descendant. The west- 
ward movement of the Indus itself is graven on the rocks with more 
than an iron pen, beside the ruins of Alor, and is indeed matter of 
almost modern history.

IN BURMAH BETWEEN SEPTEMBER 1885 AND 
DECEMBER 1886.

Tne butterflies in the following list were caught at Ran goon from 
September to December 1885, and again from May to September 
1886, at Beeling, Upper Tenasserim, from January to April 1886 ; 
and at Poungadaw, Upper Burmah, during October and November 
1886. 
The majority of specimens were caught in the pineapple gardens 
at Rangoon. These gardens, which extend for three or four miles 
from Rangoon on either side of the Prome Road, contain a 
considerable amount of low scrub jungle, interspersed with trees, 
chiefly jack-fruit, and abound in butterflies, especially Hesperidee. 
Beeling is a village about sixty miles to the north of Moulmein. 
Here the jungle consists largely of bamboo, with a fair proportion of 
large trees. The butterflies caught comprise a considerable number 
of comparatively rare species, and some which, to the best of my 
knowledge, are as yet undescribed. ‘The most prolific collecting
