In Pharella the siphons are very short and fringed at their 

 orifices, and the mantle-lobes are covered with a wrinkled 

 epidermis; the pedal orifice is terminal, and the foot is 

 straight, compressed, and truncated. The species appear to 

 inhabit the muddy estuaries of rivers, and the shells, like 

 those of Siliqiiaria, are covered with an olivaceous epi- 

 dermis.
