A, cross section, semidiagrammatic, of the abdomen in the region of the ovaries, showing a recently cast cuticula, or molt skin (Cs), a newly formed cuticula (Ci), the hypodermis (Hyp), the stomach (St), the ovaries (Ov), the heart (Ht), the ventral nerve cord (VNC), the dorsal diaphragm (DDph), tracheae (Tra), oeno- cytes (Oe), and fat cells (FC). Between the cuticula C2 and the cuticula Ci is a considerable intercu- ticular space (IS). B represents the body wall in this patholo,t,ical condition, showing the cuticula C2 and the cuticula Ci, both bearing spines (SC2 and SCi), and the intercuticular space (IS) in which is found evidence of a coagulum formed from the fluid filling the space by the action of the fixing fluids. The remainder of the body wall, the hypodermis (Hyp), and the basement membrane (BM) are also shown. C, fat eeU with irregular outline, irregular nucleus (Nu), and deep staining bodies (DSB). D, cenocyte with uniformly staining cytoplasm, and with a nucleus (Nu) having a uniform outline. E, a portion of the stomach wall showing the epithelium (SEpth) during metamorphosis, it being at this time quite columnar in type, and the musculature (M). (Original.).
