PARASITES. i6i This worm, which is more common in the dog, has been reported a num-ber of times in man. It is the largest of the nematode worms and has itshabitat in the pelvis of the kidney. Little is known of its life history. IV. Parasites of the Skin. Arthropoda. These are bilaterally symmetrical segmented animals whose segmentsdo not correspond, but vary in structure, and which primitively bear upon eachsegment a pair of jointed appendages. The segments are often more or lessfused, thus forming special body-regions which may themselves be more or less
