AMPHIBIANS AND REPTILES OF SINALOA, MEXICO 103
Mazatlan we suspect they were collected at higher elevation in the
Sierra Madre Occidental and subsequently shipped to Mexico City
from Mazatlan. An examination of the original tags indicates that
the Mazatlan referred to is the one in Sinaloa.
Dunn (1922:222) recorded a single specimen of R. pustulosa from
Mazatlan that, upon later examination, was referred to Rana montezumae
by Oliver (1937:7-8). Since fl. montezumae otherwise is
known only from the southern part of the Mexican plateau, since
the specimen examined by Oliver was "badly rubbed," since Mazatlan
represents a locality and habitat separate and distinct from
those previously known for the species (Duellman, 1961:54-55),
R. montezumae is not here included in the fauna of the state.
Distribution in Sinaloa.—Known only from the vicinity of Santa
Lucia in the southern highlands. See Fig. 33.
Specimens examined.—Mazatlan [probably incorrect] {MCZ 25756; USNM
84404); 3 mi. N Santa Lucia ("MCZ 32591-94); 1.2 mi. NE Santa Lucia
('CSCLB 1760); 1.5 km. E Santa Lucia (*KU 69159; N = 4); 5.1 mi. SW
Santa Lucia (* CSCLB 652).
Rana sinaloae Zweifel
Rana sinaloae Zweifel, Bui], So. California Acad. Science,, 53:131, December
31, 1954 (type locality, fourteen miles, by road, southwest of El Bate!,
Sinaloa, 4200 feet).
Remarks.—A series of 24 specimens agrees with the original
description. The measurements are as follows: snout-vent length,
25.8-76.8 (46.8); head width 10.2-28.9 (17.2); head length 9.7-26.5
16.2); tibia length 13.5-46.8 (25.6); tympanum diameter 1.6-5.9
(3.2). The tibia length/snout-vent length is 0.48-0.62 (0.536); the
tympanum diameter/head width is 0.16-0.21 (0.189), which agrees
with data given by Zweifel (1954a: 133), but is lower than those
reported by Duelhnan (1958b: 10) and by McDiarmid (1963:9).
Rana sinaloae occurs in tropical deciduous forest, usually along
mountain streams.
Distribution in Sinaloa.—Known only from the vicinities of
Plomosas and Santa Lucia, from about 750 to 1950 meters elevation.
See Fig. 34.
Specimens examined.—Flomosas, 760 m. (° KU 73960-65); Santa Lucia
1100 m. ("KU 75445-50; CSCLB 646); 0.6 mi. NE Santa Lucia (CSCLB
653-54); 2.2 km. NE Santa Lucia, 1150 m. (*KU 78492-96: 1.5 km. E. Santa
Lucia (° KU 44632-37); 21 km. E Santa Lucia (* KU 44631 ; 7.2 mi. W Santa
Rita (LACM 6427).
Literature record.—10 mi. NE (by rd.) El Batel, 6400 ft. (Zweifel,
1954a: 132).
Additional record.—3.2 km. SW Santa Lucia, 4000 ft. (KU 95948-49).
