MACACUS. 87 



This specimen was after its death deposited in the British Museum (68. 12. 

 29. 10.), in -which collection it has heen preserved in alcohol. It is to he regretted 

 that Swinhoe did not record the measurements of the hody as well as the length of 

 the tail, as we would thus have been in a position to gain some idea of the growth 

 of the animal during its two years of confinement. As it is, the tail now measures 

 5 inches and a half, thus indicating that this member had added an inch to its 

 length in two years. 



A careful consideration of this specimen seems to me to point in the direction 

 of M. lasiotis, more so than towards any other Eastern Asiatic monkey, but from its 

 youthful character and from the circumstance that the individual members of the 

 rhesus group of Macaques are all so very closely allied to each other and doubtless 

 have a strong common likeness in early youth, any decided opinion regarding the 

 true nature of M. sancti-johannis is hardly warranted. These remarks are equally 

 applicable to the young female monkeys from the Island of Hainan, wbich have been 

 referred by Swinboe and Sclater to Macactts rhesus. Blyth has suggested that these 

 Hainan monkeys may be M. lasiotis ; but if M. tcheliensis is the female of the latter 

 and the species is distinguished by the tail equalling only one-fourth the length of 

 the body, these Hainan monkeys can hardly be regarded as the same species, as the 

 tail of the female in question equals one-half the length of the body. No males 

 of these Hainan monkeys are known. 



Some years ago a male monkey was presented to the Zoological Gardens by 

 T. J. Eawcett, Esq., of the Hartlepool Hospital, as having come from China. It was 

 regarded while alive in the Gardens as an example of 31. sancti-johannis, Swinhoe, 

 and after its death it passed to the British Museum, under that name, which was 

 adopted by Dr. Gray as appertaining to it, and who appears to have regarded the 

 specimen as the type of the species, because in the appendix to his catalogue we find 

 him remarking, on the strength of this identification, that M. sancti-johannis is very 

 like M. cyclopis, and perhaps only a younger specimen — an observation which is in- 

 applicable to the type of M. sancti-johannis, so far at least as regards any resemblance 

 to M. cyclopis, as it has none. Mr. Eawcett's monkey, however, has all the 

 characters of 31. cyclopis, with the exception that the annulation of the hair is 

 less distinct than in that species ; but this seems to be attributable to youth, 

 for in other respects the coloration is identical with 31. cyclopis. The exact 

 locality from whence the specimen was obtained is unknown, and although I have 

 tried to trace it, I have failed to do so.
