The Northern Dutch Frill and Southern Dutch Frill are also popular, measuring 4cm less than the Parisian. In spite of the name, these were developed in Belgium and France respectively, from the hunchbacked Belgium variety.
They are the genetic forebears of the vulture-like stoop seen in many frilled Canary varieties today. This tendency is at its most pronounced in the Humpback Frill. Other misshapen varieties include the Gibber Italicus from southern Italy; the Makige Frill from Japan; the Melado Tenerife (Melado Tinerfeno) from Tenerife; the Spanish Giboso (Giboso Espanol); and the Swiss Frill.
