of 2 and 2 petioli were drawn and superimposed following a

above.

Table 2 reveals that the numbers of sagittal teeth (Fig. 2) vary 
both within E.k. and E.r., but with higher mean values in E.k., 
including the populations of E.v. and E.f. 
The volsellae and laciniae (Fig. 3, table 3) exhibit a high confor-
