Show 762 MR. A. H. GARROD ON LOPHOTRAGUS MICHIANUS. [Nov. 21, tenet], and slender, with nearly parallel sides, the largest being slightly spooned at their free ends. In most parts they are about a quarter of an inch long; but on the folds they are much shorter. Nowhere are they absent. They are all blunt-tipped and slightly crenulated along their margins. N o trace of the special gland found by Prof. Flower on the anterior wall of the paunch of the Musk could be detected. Neither in Cervulus muntjac nor in C. reevesi are the villi of the rumen flattened, they being cylindrical. The cells of the reticulum are shallow and not large, covered with minute papillae on their floors, and with a regularly arranged row on the top of each cell-wall. The psalterium resembles that of the ordinary Deer, and differs from that of Moschus in that the plicae are unequal in length. There are thirteen folds of what may be termed the first power, because they are the deepest, between each two of which one of the second power is developed. On each side of each secondary fold is a tertiary, about a quarter of an inch deep ; and, again, there is a longitudinal row of papillae on each side of each tertiary fold, which may be considered to be a rudimentary set of the fourth power. Such a psalterium may be called quadruplicate, because folds are present of four different depths. The stomach of Moschus would be simpliciplicate, were it not that there is a row of papillae developed between the plicae in some parts ; it is therefore duplicate upon the nomenclature here suggested. The abomasum presents no peculiarities. The following are the measurements of the intestines :- ft. in. Small intestine 23 2 Large intestine 9 8 Caecum 9| The colic coil was not disposed in quite the ordinary manner ; but the peculiarity was probably an individual one. At its end the large intestine made a complete transverse reduplication before turning forward from the right iliac fossa to form its terminal and irregular curve round to the sigmoid flexure. The spleen is flat on one side, domed on the other, and circular. The liver is composed of two nearly equal lobes, from the abdominal surface of the right of which is developed the triangular and laterally directed caudal lobe. The Spigelian lobe is only rudimentary, being represented by a slight tumefaction of the vertebral border of the portal fissure. There is no gall-bladder. In the arteries of the neck the arrangement is that found in the Buminantia generally, the ascending aorta giving origin, first to the left brachial with the corresponding vertebral, then to the left carotid, and finally to the same three vessels of the right side, There are thirty-eight tracheal rings above the accessory bronchus, and nine below it, making forty-seven in all. In the lungs the two lobes of the left side and the five on the right were found, the right lung being the larger. The lower lobe of each lung is comparatively small. |
