The herpetological collections made by the Hopkins Branner
Expedition to Brazil in 1911 were purchased by the California
Academy of Sciences, where they have since been stored. On the
return of the senior author from the Marshall Field Brazilian Expedi-
tion in 1926, Mr. J. R. Slevin, of the California Academy of Sciences,
wrote concerning the existence of this collection; and, after some
delays, application was made for the loan of this material, which
comes in large part from northeastern Brazil, a region of special
interest for its faunal relations with Paraguay and Matto Grosso.
We are much indebted to Mr. Slevin for his interest and trouble in
arranging for the study of this collection. The only specimens that
have been recorded from it are the Cnemidophorus ocellifer, reported
upon by Charles E. Burt in his review of the genus (1931), and the
amphisbaenas, reported in a separate paper (Schmidt, 1936). The
further twenty-four year delay in the preparation of the present
report results mainly from the failure of the plans for continued
studies in Brazilian herpetology and mammalogy formulated by the
senior author and Colin Campbell Sanborn on their return from
Brazil in 1926 and 1927, which have failed of execution through
causes beyond their control.
The personnel of the Hopkins -Branner Expedition consisted of
Dr. Harold Heath, of Stanford University; Dr. Fred Baker, of Point
Loma, California; and Dr. William M. Mann, now Director of the
