McELROY AND DOUGLAS-MORPHOLOGICAL VARIATION IN GILA 639
Fig. 2. Location of anatomical landmarks for Gila robusta and G. cypha: (a) generalized G. cypha; (b) landmark
points; and (c) a 56-character truss network derived from the landmark points. In (b), closed circles identify
anatomical landmarks, and open circles represent helping points designed to provide information on areas
of the body for which few anatomical landmarks can be identified. The truss network in (c) includes three
additional characters (dashed lines) not utilized in Douglas (1993). Definitions of landmark points are given
in the Appendix.
