Dorsal and lateral views of (a) the oval form of Notoacmea depicta, (b) A^. lepisma, and (c) the compressed form of N. depicta. and their importance almost twice that of apexpos. The second function accounts for of the variance. Widfron and width are approximately 2 to 3 times more important than any other character. Length and apexpos make the smallest contributions to function 2. The combination of positive and negative coefficients indicates that the differences between the 3 groups are not due to size but represent changes in shape. A scatter diagram of the individual discriminant scores for function 1 and function 2 (Fig. 2) shows the intermediate position of the A^. lepisma specimens. The classification computations identify 4 compressed forms of A^. depicta and 7 oval forms as specimens of A^. lepisma. Conversely, 4 specimens identified as A^. lepisma were classified as oval forms of A^. depicta. Based on the characters measured of the specimens had been correctly classified. The second analysis discriminated between the forms of A^. depicta and then classified the A^. lepisma specimens relative to these 2 forms. The single discrim- Table 2.
