DESCRIPTIONS OF FIGURES. 



FIG. 42. Transverse section through the neck near scolex. 



FIG. 43. Transverse section from middle of neck region. 



FIG. 44. Frontal section through anterior part of neck. 



FIG. 45. Sagittal section near median line from near middle of neck region. 



FIG. 46. Diagram indicating the levels from which various figures were taken. 

 The numbers correspond with the numbers of the figures. 



FIG. 47. Neck, in toto, near scolex. 



FIG. 48. Neck, in toto, near middle. 



FIG. 49. Neck, in toto ; formation of proglottids beginning. 



FIG. 50. Neck, in toto ; proglottids distinct in central parenchyma. 



FIG. 51. Neck, in toto ; proglottid-formation extending to peripheral parenchyma. 



FIG. 52. Neck, in toto; inter-proglottidal furrows distinct. 



FIG. 53. Diagrammatic transverse section through neck, indicating the planes of 

 the sections shown in various figures. The numbers correspond with the numbers of 



the figures.
