S Mazatlan, Guerrero, Mexico; collected on July 22, 1936, by Edward H. Taylor]. Taylor and Smith, 1945:581-82. Smith and Taylor, 1948:49, 50-51. _Syrrhophus pipilans pipilans_: Duellman, 1958:1-4, 8-9, 13-14, pl. 2, fig. 1. Gorham, 1966:166. _Diagnosis._--Diameter of tympanum 40.6-54.0 per cent that of eye; dorsum dark brown with large light spots or blotches. _Remarks._--Duellman's (1958) synopsis of this subspecies is adequate; the distribution has not been extended, but several records are now available which fill in gaps. [Illustration: FIG. 17: Distribution of _Syrrhophus pipilans_: _nebulosus_ (open circles) and _pipilans_ (solid circles).] Gadow's (1905) record of _S. verruculatus_ from "Buena Vista, S. Guerrero" is most likely applicable to this species. Gadow simply included the name in a list of the species he had collected during his trip in Mexico (1902-04); no further comment was made on this species although references to _Syrrhopus_ (sic) appear in several places in the paper and would appear to apply to the species he had. _Etymology._--Latin, _pipilo_, chirping, peeping, in reference to the call of the male. _Distribution._--Sea level to about 1800 meters along the Pacific versant of western Mexico from central Guerrero to the Isthmus of Tehuantepec (Fig. 17).
