Congenital anomalies in two neonatal tamarins (Saguinus oedipus and Saguinus fuscicollis).

Congenital anomalies were seen at necropsy of two neonatal tamarins. The defects included achondroplastic-like dwarfism, polydactyly and syndactyly in a Saguinus oedipus, and scoliosis and uterus didelphys in a S. fuscicollis. Both infants were the offspring of incestuous matings between twin siblings.
