FIGURE 4. Haemopis septagon Sawyer & Shelley, 1976. Digestive tract of specimens from the Albemarle Peninsula, North Carolina. Comparison of the guts. A. Terrestrial individual (HS-4). B. "Aquatic" individual (HS-3). C. Juvenile individual (HS- 5). Of taxonomic significance, the pharynx in each case is prominently wide in relation to the crop, and extends posteriorly to ganglion XI (arrow), a unique feature among mid-Atlantic Hirudinidae. Furthermore, in each case the intestine consists of anterior and posterior regions, respectively (see text). Note the crop of the juvenile is segmentally compartmentalized and displays distinct anterior and posterior crop caeca per segment, a feature almost non-existent in adults (see also Fig. 8). acc XV, anterior crop caecum of segment XV; ai, anterior intestine; c, crop; gXIII, ganglion of segment XIII; gXIX, ganglion of segment XIX; p, pharynx; pcc XV, posterior crop caecum of segment XV; pcc XIX, posterior crop caecum of segment XIX; pi, posterior intestine; r, rectum.
