784 DR. J. MURIE ON MACACUS SPECIOSUS. [June 18, 



excepting a slight portion of the right corner, which is free. The 

 right kidney is placed one inch higher than the left. Heart normal. 

 Lungs, left bilobed, right quadripartite, the middle segment of the 

 three largest is tongue-shaped, whilst the smallest one of all four 

 (lobus impar), which lies in advance, is partially incised into two tri- 

 angular lobules. Liver in breadth 6}, and in length or anteropos- 

 terior diameter 4^ inches. The main divisions of this organ are 

 into a right and a left lobe of about equal size, and a central or cystic 

 lobe larger than either of these. The two former are not cleft ; but 

 the latter has an umbilical marginal fissure and pit for the round 

 ligament, with to the right of this the usual but shallow groove 

 lodging the gall-bladder. The lobus caudatus is bayonet-shaped 

 and 2| inches long. The lobus spigelius is much smaller, flattened, 

 and oval pointed. The ductus communis choledochus enters the 

 intestine 1 inch beyond the pylorus. 



Small intestines 94 inches long, of nearly uniform (f ") diameter 

 throughout. Large intestines, including caecum, 35 inches ; the gut 

 altogether, therefore, having a length of 10 feet 9 inches. The csecal 

 appendage is a simple and wide dilatation, being almost as wide as 

 long, =2| inches. In the great gut there is a fibrous baud on either 

 side, and a number of pouched sacculi for one third of its length, 

 the constrictions of the remainder portion being irregular and very 

 small. Diminution and narrowness of the tube commences about 

 half a foot beyond the caecum . 



Stomach of nearly an ovoid figure when distended, the gullet 

 entering midway between the cardiac and pyloric ends. The narrow 

 portion towards the pylorus is considerably recurved upon the lesser 

 curvature. Measurements in the inflated condition : — great curvature 

 from gullet round to the narrowing of the pyloric extremity 9| 

 inches ; lesser curvature 1| inch. 



The c? generative apparatus has quite as remarkable a construction 

 as that of Macacus arctoides (=M. brunneus), recorded by Dr. An- 

 derson (I. c. fig. 3). This organ in M. speciosus is quite 2\ inches 

 long when erected ; and in this condition the reflected prseputium 

 occupies about f inch of the root aud body, with a diameter of 

 about ^ inch. For another \ inch or so the penis is narrower 

 but still relatively thick, and surmounted by a swelling or nodular 

 hardish prominence of the corpus cavernosus. Thence the glans 

 is narrow, straight, and tapering. Thus far there is a certain 

 similarity to what obtains in M. arctoides ; but unlike the male in- 

 tromittent organ of that Burmese Monkey, the glans in the Japanese 

 Monkey is smooth-surfaced and not beset with spines ; moreover the 

 ossicle differs, judging from Dr. Anderson's account. 



The bone of the penis in M. speciosus has a length of 2 inches, 

 and anteriorly is tipped by a short, flat, triangular cartilage, which 

 terminates in a fibrous cord mingling with the septal tissue, nar- 

 rowing at either end ; the ossicle, little more than -j^ inch in greatest 

 diameter, presents the form of a cannula, the groove placed inferiorly. 

 The bone is not perfectly straight, but has a gentle curve, especially 

 at its anterior third, which is narrowed and but slightly fluted. The
