THE SOUTH INDIAN LONG-TAILED MACAQUES. 815 



le ventre cendre-clair ; polls du sommet de la tt^te se divergeant et disposes en 

 iorme de calotte." Some details with regard to the skull and more particularly 

 relating to the form and position of the orbits are added ; but the observations 

 upon which they were based seem to have been made on menagerie material 

 and consequently to be valueless. F. Cuvier has given (Hist. Nat. Mamm. 

 Folio i, 33) a good figure of Geoffioy's radiatus, probably drawn from the type 

 specimen. The details of the bonnet are not clearly shown unfortunately, the 

 animal being drawn in profile, but the coloration as depicted and as described 

 in the original diagnosis, quoted above, corresponds with that of the Madras 

 Macaque. We therefore propose to re\ave GeoSroy's name for the Bonnet 

 Macaque of Southern India which animal must be henceforth be known as M. 

 radiata. 



The results at which we have arrived though no doubt calculated to give 

 nconvenience temporarily, smce they involve changes in the nomenclature 

 which has been accepted for more than 25 years, nevertheless have their compen- 

 sations. Firstly the name pileata which has caused much misgiving to those 

 modern mammalogists who are conversant with the Uterature of the Macaques 

 is eliminated. Secondly sinica is restored to its time honoured status as the 

 Toque of Ceylon and the confusion wMch Buffon's artist induced, after a lapse of 

 a century, in the minds of writers like Reichenbach (1862) is dispelled. Lastly 

 in reviving M. radiatus for the Madras Macaque we are only returning to the 

 nomenclature used by such pioneers of Indian Mammalogy as Sykes, Elliot, 

 Blyth, Horsfield, Kelaart and Jerdon.
