Pyloric Appendages. —In many fishes with bony skeletons there is found a cu- rious set of gland-like organs called Pyloric appendages. They vary in number from two in the Plaice, to two hundred in the Mackerel, and always either encircle the pylorus, or are found near the upper end of the intestine. These appendages are inva- riably absent in those fishes which have an imperfectly formed stomach, and by some are considered as analogous to a Pancreas in function. 354. Salivary Glands.— Salivary Glands are wanting in fishes, but their place is supplied by an increased de- velopment of the mucous glands of the mouth. 355. Digestive Organs in the Invertebrates—In the Polyps of the Radiate ani- mals, we have the simplest form of digestive apparatus, viz., a simple sack, with a mouth to receive the food and to disgorge the refuse, as is seen in Fig. 198, A. Other Polyps, however, have two openings in their stomach or sack, as shown in Fig. 198, Digestive Apparatus of a Beetle, a. Head. b. Crop and Gizzard, c. Biliary- Vessels, d. Intestine, e.
