<br />the newly created Crenichthys (La Rivers 1962). The genus Crenichthys is closely allied <br />with Empetrichthys, differing principally in the former having uniserially bifid rather <br />than biserially conical teeth, herbivorous feeding habits, and associated modifications <br />(Hubbs 1932). Prior to this work, C. baileyi was considered monotypic. <br />Bailey et al. (1970) listed White River killifish as the common name for C. baileyi. <br />However, Hubbs (1932) named C. nevadae in reference to its spring habitat (Cren <br />referring to spring). Subsequent editions of "Common and Scientific Names of Fishes" <br />should replace killifish with springfish in the common names of C. baileyi and C. nevadae. <br /> <br />ACCOUNTS OF SUBSPECIES.

(Fig. 7). <br />Diagnosis.- This subspecies differs from other C. baileyi subspecies in having a shorter <br />head and smaller least bony interorbital width (Figs. 2, 3). <br /> <br /> M <br />PRESTON F <br /> M <br />MORMON F <br /> M <br />HOT <br />CREEK p <br /> M <br />HlKO F <br /> M <br />CRYSTAL F <br /> M <br />ASH F <br /> M <br />MVWD p <br /> M <br />CARDY <br />LAMB F <br /> 255 <br /> <br />~ <br /> <br />rAIA <br /> <br />rAil <br /> <br />rll JII II <br /> <br />rvmn <br /> <br />r/A't/1 <br /> <br />r/}/1I <br /> <br />fJJ,.. <br /> <br />mhn <br /> <br />r/~/" <br /> <br />lIllI/h, UI n <br /> <br />1/11 II <br /> <br />.JlbL <br /> <br />r/tH <br /> <br />I,,,h fA <br /> <br />r/INu .. <br /> <br />275 <br /> <br />295 <br /> <br />315 <br /> <br />335 <br /> <br />355 <br /> <br />HEAD LENG'rn/STANDARD LENG'rn <br /> <br />Fig. 2.
