The skull of the type is unfortunately somewhat broken. 

 It has a very characteristic appearance with a rather deep 

 depression in the frontal region behind the roof of the or- 

 bits. Total length (approximately) 59 mm.; occipitonasal 

 length 54 mm.; width of brain case 34 mm. The teeth of 

 the present form appear to be larger than in C. cwpreus, 

 because the length of the upper molar series is, although 

 the teeth are rather much worn, about 14,5 mm., and the 

 length of the lower molar series is 16 mm. (against resp. 14 

 and 15 mm. in C. cupreus). If thus all is taken together, 

 the present specimens appear to be easily distinguished from 

 other forms of Gallicebus, although the differences are not 

 so very great.
