Anotations

Scope note:

Shape or form delimited by two curves intersecting so as to delimit a space that is overall narrow but wider in the middle and tapering to a point on both ends (sometimes only on one end), thus resembling a spear or lance-head. For similar forms that are overall wider, use "almond-shaped."
