APPENDIX 259 
CEBUS CURTUS Bangs. 
Cebus curtus Bangs, Bull. Mus. Comp. Zool. Cambr. Mass., 
XLVI, 1905, p. 91. 
Type locality. Gorgona Island, off southern coast of Colombia, 
S. A. Type in Museum of Comparative Zoology. 
Genl. Char. Similar in color to C. capucina (Linn.) but hands 
and feet smaller, tail shorter, and last molar smaller. 
Measurements. Total length, 753; tail, 420; foot, 115. Skull: 
Occipito-nasal length, 80.4; intertemporal width, 38.4; zygomatic 
width, 58.4; palatal length, 33.6; length of upper tooth row, 25; length 
of mandible, 58; length of lower tooth row, 28. Ex type in Museum 
of Comparative Zoology. 
Very lately, through the kindness of my friend Mr. O. Bangs, 
I have been able to examine the type and a young example of this 
monkey. It differs from C. cAPUCINA as stated above, and agrees with 
C. c. nigripectus in its shorter tooth row, and small last molar. The 
short tail in each example appears to be natural, but it will require 
more specimens from the island before it can be satisfactorily deter- 
mined whether or not this member has been abbreviated by the animal 
itself or by some other agent. The tails of both examples are equally 
short.
