This variety is even more empliasized in its emaciated condition 

 than the specimens figured by Dr. Brady from tidal river deposits of 

 the River Blythe, Northumberland, and the River Wear, 2 miles 

 above Sunderland, although some examples from Heiigistbury Head 

 match it almost exactly excepting in the less open umbilicus. 



In the recent and brackish mud deposits, as pointed out by Brady, 

 the tests seem to show that the emaciated appearance is due to the 

 falling in of the thin, chitinous, and sparsely arenaceous walls, from 

 the contraction of the protoplasm in drying. 



The specific form T. inflata is usually found in moderately shallow 

 marine to brackish waters round the British coast.
