Show 134 ME. F. E. BEDDAED ON THE YISCEEAL ANATOMY [Feb. 5, spoon-like fashion at one end. The organ is not T-shaped, as in D. inustus and the Kangaroo. The small intestine measures 95 inches; I could only count 6 Peyer's patches in it. The cou joined bile and pancreatic ducts open into it at a distance of five inches from the pylorus. The Urge intestine neasured 38 inches ; it has, as has the ca?cum, plenty of Peyer's patches. Mr. Dobson, in recording1 the existence of Peyer's patches in certain Insectivora, Rodentia, Marsupialia, and Lemurs, omitted to mention that Owen bad discovered these structures as existing in the colon of Dendrolagus inustus. The ccecum of the present species appears to be smaller than that of D. inustus, in which animal the measurements given by Owen are 5 x 5 inches. I found it to be 2 inches only in length and about the same in diameter. The ca?cum is attached to the small intestine by a sheet of membrane. From the opposite side of the small intestine a fold comes over, which is attached to the first-mentioned membrane. It is for the most part anangious. The blood-vessel supplying the ca?cum comes across from the ileocolic mesentery on the opposite side, where there is no connecting fold of membrane. The arrangement of the membranes supporting the ca?cum is precisely the same in Petrogcde penicillata and in Halmaturus bennetti; but in the former, at any rate, the accessory fold which joins the ileo-ca?cal fold bears a blood-vessel along its free edge. § The Liver. I have thought it worth while to have a drawing made of the liver of Dendrolagus (fig. 3), which was not particularly described by Fig. 3. Liver of Dendrolagus; abdominal surface. Sp., Spigelian lobe; L.L., left lateral; L.C., left central; B.C., right central; E.L., right lateral; Ca., caudate; 67, gall-bladder. 1 J. Anat. Phys. 1884. |
