Recognition of webbing of the neck dates from 1883, when Kobylinski3 described it. Four cases were added by Frawley,4 all in females. Webbing occurs in the Klippel-Feil syndrome, also, apparently a commoner variety, but it is associated with synostosis of the cervical vertebrae with limitation of motion, and there is no infantilism. By these characteristics the Klippel-Feil syndrome is easily differentiated from Turner's.
