of parameters, with a primary ridge in one region and 

 secondary, tertiary, and quaternary ridges in the other, 

 were evaluated in an attempt to find parameters 

 selected by the SRLCA test function that would inter- 

 pret the 1984-1988 distributions in accordance with 

 a priori assumptions. 



The primary ridge ranged from L,„f = 43 mm. K = 

 0.50 to a boundary maximum at L,„f=50 mm. 

 K = 0.37. The highest nonboundary score was at L,,,,- 

 = 48.0 mm, K = 0.40. A secondary ridge ranged from 

 L,„f=35 mm, K = 0.50 to L,„f = 50. K = 0.21, with a 

 nonboundary maximum score at L,,,,- = 42.0, K = 0.30. 

 A tertiary ridge ranged from L,nf = 32 mm, K = 0.50 

 to Linf = 43 mm, K = 0.20, with a nonboundary max- 

 imum at Li„f = 32 mm, K = 0.49. A quaternary ridge 

 ranged from L,n, = 33 mm, K = 0.33 to Ljnf = 38 mm, 

 K = 0.20, with a nonboundary maximum score at L,nf 

 = 33 mm, K = 0.32 (Table (3," Fig. 13).
