Head and body length of the reed titi ranges from 9.5 inches to 24 inches, and its tail length ranges from 10 inches to 21.5 inches. Weight ranges from 18 ounces to 26 ounces. The non-prehensile tail is well haired and sometimes tufted at the tip. The hair is long and soft. Coloration is variable; it ranges from reddish gray or yellowish through reddish brown to black on the upper parts, and is usually paler on the under parts. A light-colored collar band is sometimes present. Some Titis have a black band on the forehead, while others have a white band. These monkeys, with their harmonious colors and thick, soft fur, are attractive animals. The head is small and rounded, and the face is high and somewhat flattened.
