 about four similar furrows. Colour hyaline white. Mouth long, 

 narrow, curved throughout its whole length. Outer lip rises very

 is there slightly emarginate. Top is small, oblique, and has a con- 

 ical depression in the middle behind the lip. Inner lip flatly curved 

 on the body ; the pillar is almost quite straight but a little oblique 

 in its direction. There is a very faint appearance of a tooth on it in
