County, New Mexico, he left the Arizona-New Mexico population as 

 P. t. triseriata. His criterion was the greater tibia length/body 

 length ratio in frogs from the latter states. Five specimens from 

 the Zunis have ratios of 38.8-43.5 (x 40.9 ±0.4), thus placing them as 

 P. t. triseriata x P. t. maculata intergrades (cf. Smith, 1956, table 2). 



Recently transformed specimens, 13 and 14 mm. snout-vent, were 

 collected July 13, 1949, in a meadow of the spruce-fir association at 

 about 9200 feet. They were thought to be singing at the time of 

 capture (Chenoweth, 1950, p. 532), but this seems improbable in view 

 of their humaturity. Three males, also judged to be singing, were 

 collected May 21, 1924, by Charles L. Camp at 7000 feet; they measure 

 29, 30, and 31 mm. snout-vent and are reproductively mature. All 

 Zuni specimens have three distinct dorsal stripes that are broken 

 posteriorly in the three adults.

Rana pipiens Schreber 



I have not attempted to assign Zuni leopard frogs to any particular 

 geographic race in view of the notorious variability and inadequate 

 definition of the various proposed subspecies (e.g., see Moore, 1944). 

 In the study area these frogs may be many shades of green, brown, or 

 gray; but they usually have 5-12 (x 9.1) large, regularly arranged 

 dorsal spots and smooth sldn. With respect to the latter feature, 

 they are quite different from the highly pustulose leopard frogs 

 occurring near Snowflake, Navajo County (UMMZ 121949), and 13 

 miles west of Chevalon, Coconino County (UMMZ 121951), Arizona, 

 although from the same dramage system (Colorado River). The 

 preserved specimens are small and may not represent the typical 

 adult size range (table 4). A single female is 55 mm. snout-vent. 



Lack of a large series and the few locality records reflect only the 

 amount of attention directed toward collecting this species. My 

 field notes indicate that R. pipiens is one of the most abundant 

 anurans in the Zunis; it was seen commonly around isolated pools 

 and streams in the riparian association of Roughlands and Montane 

 Life Belts. Coues (1875, p. 631) found it to be similarly abundant 

 along the Zuni River and Rio Gallo near Ft. Wingate. I did not 

 see R. pipiens in cattle tanks or roadside ditches, nor did I note any 

 breeding activity; however, larvae of all sizes were found throughout 

 the summer months, and a great concentration of recently transformed 

 individuals, 9-25 (x 21.6) mm, snout-vent (Nl=5),was noted August 

 21-23, 1959, at 7200 feet.
