2. 3. 4. 5. PLAIN WHORL
A PLAINWHORL consists of one or more ridges which make a complete circuit, with two deltas, between which, when an imaginary line is drawn, at least one recurving ridge within the inner pattern area is cut or touched.
6. WHORLS
Minimum requirements:2 deltas and recurving ridge in front of each.
It can be spiral, oval, circular, or any variant of a circle.
An imaginary line drawn from delta to delta MUST cut or touch at least 1 recurving ridge within the inner pattern area.

11. 12. 13. CENTRAL POCKET LOOP WHORL
A CENTRAL POCKET LOOP WHORL consists of at least one recurving ridge, or an obstruction at right angle to the line of flow, with two deltas, between which, when an imaginary line is drawn, no recurving ridge within the inner pattern area is cut or touched.
14. CENTRAL POCKET LOOP WHORL
DIFFERENCE FROM A PLAIN WHORL - an imaginary line drawn from delta to delta must not cut or touch a recurving ridge in front of the inner delta.
15. LINE OF FLOW
THE LINE OF FLOW OF A CENTRAL POCKET LOOP WHORL is determined by drawing an imaginary line between the inner delta and the center of the innermost recurving ridge.

31. 32. 33. ACCIDENTAL WHORL
AN ACCIDENTAL WHORL consists of a combination of two different types of patterns with the exception of the plain arch, with two or more deltas or a pattern which possesses some of the requirements for two or more different types or a pattern which conforms to none of the definitions.

EXCEPTION:
A loop over a plain arch is classified
as a loop.(generally called a lazy loop)

EXCEPTION:
A tented arch over a loop is classified
as a loop.
40. ACCIDENTAL WHORL
EXCEPTION:
Two loops joined as one over a plain arch
is classified as a Plain Whorl.
41. WHORL TRACINGS
Trace from left delta, to a point opposite the right delta.
Trace from the farthest left delta to a point opposite the farthest right delta when there are three or more deltas present.
Drop down at ending ridges.Follow the lower fork of a bifurcation.
Stop at the point opposite the right delta and count ridges between that point and the delta.
If there are three or more ridges inside the right delta , the tracing is an - I - INNER.
42. WHORL TRACINGS
If there are three or more ridges outside the right delta, the tracing is an - O - OUTER.
If there are one or two ridges either inside or outside the right delta, or if the tracing stops on the right delta itself,the tracing is an - M - MEETING.
8.It is not necessary to count more than three ridges.
Do not count delta or tracing ridge.The tracing ridge is the ridge where the tracing stopped opposite the right delta.
