| 内容記述 | 1. In the adult of Squilla oratoria there is found an anal gland composed of four semi-transparent sacs situated on both sides of the anal-split ; that is, one pair of anterior sacs and one pair of posterior sacs. 2. Both of the anterior sacs contain a small white ring, a concretion, while in the posterior sacs no such concretion is found. 3. Both the anterior and the posterior sacs are hooped with bundles of muscle fibres running meridionally and latitudially, and the former is more thickly hooped with muscle fibres than the latter. 4. Each of the anterior sacs communicates into the posterior and dorsal end of the anal-split on each side with a minute duct which reaches to the groove that is formed at the junction of the rectum and the anal-split. 5. The posterior sacs of both sides unite, at their proximal ends, into a common short duct, and the duct communicates into the posterior end of the ducts of the anterior sacs. 6. The wall of the anterior and the posterior sacs is made of three layers of different kinds of cells : that is, 1) glandular epithelium, 2) basal membrane, and 3) muscle layer. The glandular epi\ thelium of the anterior sacs is a one-celled layer of glandular cells, and the cells, containing round or oval nuclei, bear a cuticular saum on their surfaces, and are arranged regularly in succession, lined clearly by the cell membrane. 7. The anterior sac, enclosed by the basal membrane, is hooped with bundles of muscle fibres running meridionally and latitudinally, especially, on its distal hemisphere, it is hooped more thickly with muscle fibres. 8. The glandular epithelium of the posterior sacs lacks the cuticular saum and is thinner than that of the anterior sacs, and the component cells lack cell membranes. The nuclei of these cells are larger than those of the anterior sacs. It is to be noted that the nucleus contains a nucleolus, while in that of the anterior sacs no nucleolus is found. 9. The muscle layer of the posterior sacs is thicker than that of the anterior sacs. 10. In the posterior sacs, there are many mesh-like blood sinuses between the basal membrane and the muscle layer. |
