Rana pustulosa Boulenger
Rana pustulosa Boulenger, Ann. Mag. Nat Hist., ser. 5, 11:343, May, 1883
(type locality, Ventanas, Durango),
Remarks.—We have examined six frogs and four tadpoles. The
frogs have the following measurements: snout-vent length 49.9-
75.4 (56.1); tibia length 28.3-43.9 (31.3); head length 19.7-30.0
(22.2); head width 17.3-26.8 (19.5). The tibia length/snout-vent
length is 0.54-0.58 (0.557); head length/snout-vent length is 0.39-
0.41 (0.396); head width/snout-vent length is 0.33-0.35 (0.347);
head width/head length is 0.84-0.89 (0.875). The tadpoles, two of
which were metamorphosing when preserved on June 23, 1955,
agree closely with the descriptions and illustrations given by Taylor
(1942a144-45, pi. I, fig. 1, pi. Ill, fig. 4) and Zweifel (1955:251, fig.
22). The tadpoles were found in the rapids of a canyon stream.
The proximity of the type locality to Sinaloa, and the range of
the species to the south, suggest that Rana pustulosa probably occurs
in the mountains of southeastern Sinaloa. Two specimens (USNM
84404-05) were sent to the U. S. National Museum in November,
1921, by the Departmento de Exploracion Biologia Republica Mexicana.
One of these (USNM 84405) was sent to the Museum of
Comparative Zoology on February 21, 1944, and identified as Rana
sinaloae (MCZ 25756). Zweifel (1954a: 135-36) discussed the National
Museum specimen (84404, not 34404 as published by Zweifel)
and pointed out that it is either Rana pustulosa or sinaloae but definitely
not R. pipiens (the only other logical possibility for the area).
Examination of both specimens indicates that the frogs probably
are R. pustulosa. Although the specimens are listed as coming from
