SUB.T 0C T:
Because of the possible discovery of a remnant population
of Gila cypha, encouragement can be given to preserving this rare
and endangered species. This paper concentrates on. identifying
fish found by the Grand Junction Division of Wildlife sampling
team, August 22, 1974.
SCOPE:
Areas covered in this report will. include history, tpxonom;;,
distribution, and likelihood of survival of the fish.. Since the,
distinction between Gila cjpha and Gila elega.ns is not clear,
and hybridization between the species is common, particular atten-
tion will be given to the possibility that specimens collfrcted
were intergrade forms (see Def.). For the purpose of this study,
I assume the validity of the three species in genus Gila: G. ro-
busta, G. elep-ans, and G. c ha as seen in (Fig. 1) (1:32). The
intergrade forms appear in Figure 2.
HISTORY:
The most extensive work done concerning G. cv ha was probably
by Mr. Paul Holden and Dr. Clair B. Stalnaker.
