DR. J. MURIE ON MACACUS CYCLOPIS. 



77 



Macacus, as given by Mivart, 'Trans. Roy. Soc' 1867, tables, pp. 

 377 to 388 inclusive. Tbe tail is from my own measurement of the 

 same Hunterian specimen, No. 4991 . The notes of interrogation are 

 appended where the exact length could not be relied on, from injury 

 or otherwise. Inches and decimals are used, and 100 taken as the 

 standard of proportions. 



Table showing relations of Spine and Limb-bones. 



It may be gathered from the above approximations that tbe entire 

 pectoral and pelvic limbs of the Formosan Monkey are both abso- 

 lutely and proportionally shorter than in the Rhesus. The same ob- 

 tains in these extremities, minus the manus. It is further noticeable 

 that the female exceeds the male of M. cyclopis in the latter propor- 

 tions. The humerus, radius, femur, and tibia, which respectively 

 are comparable as indicating fore- and hind-limb segments, are all of 

 smaller ratio in the Chinese form. The manus, on the contrary, 

 both absolutely and relatively, is the reverse, or smallest, in the 

 Indian animal ; but not so the hind foot or pes. 



Reverting for a moment to Mivart's careful observations, it would 

 seem that our Round-faced Monkey, in the proportionate dimensions 

 of fore limb to spine's length, presents closest agreement vvithMan and 

 Cynocephalus. The humerus to spine is again nearer the latter than 

 M. rhesus. Manus to spine has a Gorilla-like proportion. The 

 entire pelvic limb is in concord with the Rhesus and Cynocephalus, 

 and without the foot is nighest the latter and its fellow. The rela- 

 tions of femur to vertebral column approach quite as much to Cerco- 

 pithecus and Cynocephalus as M. rhesus. Tibial proportion inclines 

 to the Baboon and Semnopithecus ; and the foot (pes) is not far out 

 from the latter and the Rhesus, but much longer than in Cynoce- 

 phalus.
