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 CEBIDA: 
Subfamily. Callimiconinze 
GENUS CALLIMICO. 
L =. Cc. 3 r, =. M. ae 
¥ 
Skull has a high and rounded braincase, 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 CEBIDA. 
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: 
CALLIMICO GOELDI (Thomas).
