The central core of cells gradually becomes differentiated into a digestive tract, separated from the body wall by a true body Fig. Mature larvse of Filaria bancrofti in thoracic muscles and proboscis of mosquito.

(TV of an inch) in length — the digestive tract is a com- plete tube with both mouth and anal openings. While these changes are taking place, the larval worm, though capable of activity, remains at rest between the muscle fibers (Fig. 126),.
