These specimens of the Ladder-backed Woodpecker show signs of intergradation with _D. s. symplectus_. Both specimens are pale enough above for _D. s. symplectus_, but the wing and the tail of each (wing, 102, 103 mm.; tail, 60, 65 mm.) are too long for _symplectus_. This suggestion of intergradation is not unexpected because _symplectus_ occurs in northeastern Coahuila and _cactophilus_ in the Chisos Mountains of Texas. Miller (1955a:166) also obtained one female _D. s. cactophilus_ from the Sierra del Carmen that suggested intergradation with _symplectus_. Miller (_loc. cit._) wrote that _D. c. cactophilus_ was found chiefly in the oaks and was common in the lower oak belt at 5000 feet. The upper limit of the range of the Ladder-backed Woodpecker, according to Miller, is 6800 feet. He reported the species as breeding in the Sierra del Carmen. Miller (1955b:317) took a hybrid woodpecker representing a cross between _Dendrocopos villosus_ and _Dendrocopos scalaris_ in the Sierra del Carmen, where, although Ladder-backed Woodpeckers were common, he found no Hairy Woodpeckers. **_Dendrocopos scalaris symplectus_ (Oberholser).--_Specimens examined:_ total 2: [Male] 32058 from 2 mi. W Jimenez, June 20, 1952; and [Male] 31667 from Sierra Guadalupe, Domingo Canyon (=10 mi. S, 14 mi. W General Cepeda), 6700 ft., April 18, 1953. This Ladder-backed Woodpecker, according to the AOU Check-list Committee (1957:327) and Oberholser (1912:156), occurs in Texas (east of Pecos), northeastern Coahuila, Nuevo Leon, and Tamaulipas. The area of intergradation of _D. s. symplectus_ and _giraudi_ is in southeastern Coahuila. The dark smoky underparts and the equal size of the white and black bars of the upper parts of No. 31667 suggest intergradation with _D. s. giraudi_. Yet, the size of the wing indicates that this specimen is closer to _D. s. symplectus_. No. 32058 has characters of typical representatives of _D. s. symplectus_. Burleigh and Lowery (1942:193) reported _D. s. symplectus_ "in the desert country west of Saltillo." Ridgway (1914:257) listed the Ladder-backed Woodpecker from Sabinas. Cory (1919:494) listed _D. s. symplectus_ from Pabinas (=Sabinas?). **_Dendrocopos scalaris giraudi_ (Stone).--_Specimen examined:_ one, [Male] 34623, from 12 mi. N, 10 mi. E Parras, 3850 ft., July 12, 1953, weight, 35 gms. Ridgway (1914:259) reported that _D. s. giraudi_ (then called _Dryobates scalaris bairdi_) has been recorded from La Ventura, Carneros, and Jaral. Oberholser (1912:159) indicated that the subspecies _giraudi_ occurs north to Jaral in southern Coahuila, east to La Ventura in southeastern Coahuila, and south through central Mexico. The present specimen is darker ventrally than specimens of either _D. s. cactophilus_ or _D. s. symplectus_, and on its upper surface the black bars are wider than the white. The specimen is in worn plumage, but nevertheless suggests intergradation with _D. s. symplectus_.
