Show 10 MESSRS. F. E. BEDDARD AND F. TREVES ON THE [Jan. 15, region of the gut with blood, if the circulation in the main arteries happened to be occluded. In the Sumatran Rhinoceros the same fold occurs ; but (at least in one specimen) it was of limited extent compared to the fold in the Sondaic Rhinoceros ; it commenced at about the same point, but terminated at the beginning of the smooth portion of the colic loop. Furthermore this fold appeared to have no artery ; or if an artery was present it must have been very small indeed. The ileo-csecal fossa figured and described by us in Rhinoceros sondaicus was present in the Sumatran species ; but, instead of being large enough to contain the entire fist, it was only of the diameter of the fore finger; this difference is not at all commensurate with the difference in size of the individuals of the two species. Fig. 2 (p. 11) represents the nasal diverticulum of this species ; this organ, which is known to occur in the Horse and in the Tapir, has not yet been described in the Rhinoceros; as will be seen from the figure, it is not widely different from that of the Tapir. Our figure maybe compared with the late H. N. Turner's figure (P. Z. S. 1850, p. 104) of the same organ in Tapirus americanus. On some of the Muscles of the Fore Limb. Rhomboideus.-A small muscle, 8 inches wide, fleshy. It is inserted into the whole length of the vertebral border of the scapula. Levator anguli scapuli.-A separate one cannot be made out. Serratus magnus.-An enormous fleshy muscle with very coarse fibres inserted into the venter of the scapula over a surface 1 0 in. by 6 in. Insertion comes between rhomboideus and subscapularis. Subscapularis.-This muscle is aponeurotic on the surface, muscular beneath. Arises from whole of the venter of scapula beyond serratus magnus. In contact with supraspinatus above and overlapped origin of triceps below. Arises from aponeurotic covering of triceps. Lower border intimately blended with teres major. It is inserted into the trochanter by a wide tendon. It crossed capsule ; bursa between it and capsule in communication with the joint. Latissimus dorsi.-Crossed whole of triceps, then ran parallel with and underneath teres major. Inserted into front of humerus by a tendon. This tendon was below the trochanter and to the extensor side of the biceps, and under the coraco-brachialis; it was common to the latissimus dorsi and teres major. The great bulk of the latissimus dorsi ended in an aponeurosis. This blended with the aponeurosis of the triceps about four inches from the humerus • the rest passed down and joined the fascia of the forearm over the ulna. Teres major (fig. 3).-It lies between subscapularis and latissimus dorsi. It arose from inferior angle of scapula, from part of its inferior border, and from aponeurosis at origin of the triceps. Joined the latissimus dorsi. Coraco-brachialis.-Arises by a strong tendon from the coracoid |
