In the caterpillar he foundthe gullet, the honey stomach, the true stomach, andthe intestines capacious. Two days after its firstchange all these are visibly diminished, as well as thesilk reservoirs, which, in a chrysalis eight days old,have wholly disappeared; Mhile the base of the gulle<is dilated into a crop, and the stomach still more contractcd into a spindle form. When near its changeinto the perfect insect the gullet is still more drawnout, while the crop, still small, is now on one side of VISCERA OF THE C0S3US. 199 View of the upper side.
