The Amphibians and Reptiles of Sinaloa, Mexico - Smithsonian ...

42 UNIVERSITY OF KANSAS PUBLS., MUS. NAT. HIST,
evolution of the amphibians and reptiles in the Pacific lowlands of
western Mexico. The following summer, the first author collected
amphibians and reptiles in Sinaloa and made ecologic observations.
On the basis of the latter material and preserved specimens in the
collection of the University of Kansas, the first author initiated a
study of the amphibians and reptiles of Sinaloa. Early in 1964
we started correspondence that pointed up the similarities of our
studies, and as a result combined our efforts toward preparation
of this publication based primarily on specimens readily available
to us.
