APPENDIX 2 



In Volume I, on page 324, is a description of Callithrix goeldi 

 founded on a specimen in the collection of the British Museum. This 

 example was in poor condition and without a skull, and was reluctantly 

 admitted as a distinct species, although it could not be assigned to any 

 known form. Lately Mr. Thomas received some examples of mam- 

 mals from the Para Museum, among which was a C. goeldi with its 

 skull. This proves to have a remarkable interest and establishes the 

 fact that this monkey is not only distinct from all others, but also 

 represents a distinct genus to be assigned as follows : 



FAMILY CEBID/E 



Subfamily. Callimiconinae 



GENUS CALLIMICO. 



I. S; C. rli; P- si?; M- S = 36- 



Skull has a high and rounded hraincase, brow ridges not promi- 

 nent ; with superior outline from nasals to occiput convex ; malar verti- 

 cally expanded ; mandible with chin and incisor as in the Cebid.*:. 

 Orbits more slanting than in Callithrix, but pterygoids like those of 

 that genus. Molars like Callithrix, but broader and without hypocone ; 

 lower incisors and canines normal. Externally the animal resembles 

 the Marmosets, with long, curved compressed claws. 



The species will stand as follows ;
