Show 290 MR. W. A. FORBES ON THE GREAT ANTEATER. [Mar. 7, that having been found in Gervais's specimen (perhaps in two), in Owen's, and in one of mine for certain. ov„„f1v aq described hZXXekL^n\eae^ the other duct an opening by a single aperture into the mouth (vide Plate X V . % 3) At the point where the three submaxillary ducts ot eacn side coming K e three lobes of the gland, converge, and become united lately by their walls to each other, they ^ » ™ " g ? * * a bulb-like mass of muscular issue, the exac relations of which 1 shall describe below. But I could not perceive that this structure, which externally looks like a bulbous reservoir surrounded by a muscular coat, corresponded to any dilatation of the ducts which pass through it; on the contrary, these seem to preserve a nearly uniform diameter throughout this part of their course, a condition corresponding to that described by Chatin in Tamandua. . The terminal reservoirs, I may add, of the two pairs of submaxillary ducts lie iust above the long thin median tendon of the genio-hyoid, the contraction of which muscle may possibly, by compressing the floors of these reservoirs, aid in the ejaculation of the fluid contained " ThTstomach of Myrmecophaga generally resembles Prof Owen's figures and description ; but the thick pyloric pads are softer and more vascular, and the whole less gizzard-like, than I had been led to anticipate from his account. The gyriform folds of the mucous membrane of the cardiac part of the stomach, which quite resemble those of the stomach in many other animals, are, in particular, not happily represented in his fig. 1, pl- hi. The" liver of both specimens agrees very well with Prof Flower s description of this viscus. Both caudate and Spigelian lobes are practically absent. . As accurately described by Pouchet (' Memoires, pp. 191,192 ), the pancreatic duct ends in a vesicle, in the walls of which the hepatic duct runs for a little way and then opens into it, the vesicle then opening by a separate aperture into the duodenum. In the first (larger) specimen examined by me the intestines measured as follows -.-small intestine 24 ft. 10 in., large intestine 2 tt. 3| inches. The csecum can hardly be said to exist as a separate part. The median longitudinal ridge of mucous membrane was continuous for the posterior 15 feet 3 inches of the small intestine, and reappeared above this at intervals in a less regular and less developed way. I could see no longitudinal folds of mucous membrane, such as are described by Owen, in the rectum, which, however, had distinctly transverse ones, irregularly disposed in a gyriform way, well marked. The right lung is trilobed, with an azygos lobe superadded ; the left lung is bilobed, the lowest lobe in each lung being biggest. The kidneys are quite smooth externally : there are no distinct Malpighian pyramids, the tubules opening internally on a single |
