droid; oesophagus somewhat cylindroid, but presenting a more or less spheroidal 

 bulb about the mandibles. At the base of the neck, the oesophagus is two-thirds 

 as wide as the corresponding portion of the body. Its lining is more or less dis- 

 tinct; its musculature colorless. The rather thick-walled intestine has a faint 

 lumen, and becomes at once five-sixths as wide as the body. Throughout the

body under the cuticle, there are coarsely granular, spherical organs one-fourth 

 to one-third as wide as the body, located in the lateral fields, and separated 

 from each other longitudinally by a distance about equal to the body diameter. 

 It is probable that the female organs are double, and symmetrically reflexed.
