 Hah. in valle fluminis Tista, in provincia Sikhim interiors

This is a much larger shell than M. sequax with a different 

 sculpture. The spaces between the longitudinal impressed lines 

 appear papillose when considerably magnified.

 This minute shell, found commonly amongst the debris left 

 behind by river-floods, was named in MS. by the late Rev. S. B. 

 Fairbank 40 years ago, and was mentioned in a report of mine 

 written in 1866 and published in my absence in the Records of the 

 Geological Survey of India, vol. i. 1870, p. 62. The typical 

 specimens are from Paitan near Ahmednagar, and I have spe- 

 cimens from various places as far to the south-east as the first 

 barrier on the Godavari at Dumagudem, also from the Wardha near 

 ISTagpur, and I believe I had some from the Nerbudda Valley. 



This is probably not a Macrochlamys but the animal is unknown, 

 only dead shells having been found. The only allied Indian form 

 appears to be M. anonce G.-A., from Calcutta, a much less depressed 

 shell.
