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-czecal 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 
may be 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 in- 
serted 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 10 in. by 
6 in. Insertion comes between rhomboideus and subscapularis. 
Subseapularis.—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
