For most of our specimens, we are indebted to Mr, Lidderdale, who took 
much trouble on our behalf. Living on the river, and having many coolies 
under his supervision, he organized beats with a view to driving these 
creatures from the bushes bordering the river bank, but found that they 
usually escaped into the water when flushed, and got away. Subsequent 
beats however undertaken at very low tide, caused the creatures when 
making a bid for the water, to throw themselves into the soft mud, which 
so hampered their movements, as to permit of their easy capture,
