Taenia chamissonii n. sp. 1. Cyst cut open on one side, showing the outer and thicker connective tissue layer c of the cyst proper, the inner and thinner layer bl or bladder, the point of invertion i, and the filiform, inverted portion t. Actual length of cyst 30 mm. 2. Bladder removed from cyst, opened and reflected, showing the filiform portion with its point of attachment and the blunt, inverted scolex. Enlarged about 2 diameters. 3. A large cyst, 48 by 40 by 22 mm. in the three principal diameters. The outer wall has been cut open and reflecgted, showing that what at first appeared to be one cyst has others included within its outer wall. Each of the included cysts is surrounded by connective tissue. Upon removal ofthe outer coat there appeared to be three cysts inclosed, c’. One of these, after further removal of connective tissue, was found to inclose two cysts, c’’. In other words, the primary cyst inclosed four bladder worms, which, starting from four larvae near together, gresw and became enveloped, at first in individual cysts and later in a common cyst, c. 4. Cysticercus removed from cyst. The filiform portion is protruding from a perforation in the wall of the bladder. 5. Another cysticercus with a window cut in the wall to show that the filiform portion is not everted, but is perforating the wall. 6. Transverse section of filiform portion of cysticercus near the scolex. The section was 0.45 by 0.37 mm. in the two principal diameters. 7. Transverse section of filiform portion of cysticercus near middle of its length. The section was 0.66 by 0.50 mm in the two principal diameters. 8. A nearly transverse section through the scolex. 9. A nearly longitudinal section through the scolex. 10. A cysticercus with a portion of the bladder cut away so as to show the pore on the exterior and its continuation in the filiform portion. 11. Diagram showing the relation of the bladder to the inverted fifiform portion and scolex. 12. Pedicelated cyst; actual length of cyst, not including pedicel, 30 mm. Figures 1 to 7 from lot collected October 7, 1901; figures 8 to 10 and 12 from lot collected July 29, 1899. Abbreviations: b, suckers of scolex; bl, bladder of cysticercus; c, c’, c’’, cyst of connective tissue inclosing bladder; cu, cuticle; ex, external pore communicating with inverted portion of cysticercus; g, granulo-fibrous layer of inverted portion of cysticercus; i, folds on inner wall of bladder at point of invertion; l, fine longitudinal fibers; lv, lateral, longitudinal vessels of inverted portion of cysticercus; m, lumen of inverted portion of cysticercus; p, parenchyma; s, scolex; t, filiform inverted portion of cysticercus. |
