Miller (1955a:164) took a male Great Horned Owl in the Sierra del Carmen on April 22. Ridgway (1914:742) listed _B. v. pallescens_ from Sabinas. Sutton and Burleigh (1939a:30) obtained a female "near San Pedro" on January 29. Friedmann, Griscom, and Moore (1950:143) recorded _B. v. pallescens_ from Coahuila on February 24, May 26, and June 10. The record of _B. v. mayensis_ from Las Delicias (Amadon and Phillips, 1947:578) has been reidentified by Webster and Orr (1958:141) as _B. v. pallescens_. Dickerman saw a Great Horned Owl in the Sierra del Pino on May 12,1954.
*_Glaucidium gnoma californicum_ Sclater.--_Specimen examined:_ one, [Male] 31582, from 20 mi. S Ocampo, 6500 ft., April 5, 1954, weight, 55 gms.
Concerning forms of Pygmy Owls, Miller (1955a:164) remarked that the best distinguishing characters of _G. g. gnoma_ and _californicum_ are tail length and wing length. The characters of No. 31582 (wing, 94 mm.; tail, 69 mm.) are clearly those of _californicum_ and not those of _gnoma_. Miller (_loc. cit._) remarked that he "encountered at least five different individuals, chiefly in the pine-oak at 7000 feet" and one in oaks and piñons at 5000 feet in Boquillas Canyon of the Sierra del Carmen. The size of the testes (left, 9×5 mm.; right, 7×4 mm.) of No. 31582 indicates good probability of breeding by the Pygmy Owl in the State.
**_Micrathene whitneyi_ (Cooper).--Miller (1955a:164) heard the Elf Owl at close range in oaks at 5000 feet in Boquillas Canyon of the Sierra del Carmen on April 24.
**_Speotyto cunicularia hypugaea_ (Bonaparte).--_Specimens examined:_ total 3: [Female] 32043 from 3 mi. S, 9 mi. E Cuatro Ciénegas, 2250 ft., June 30, 1952; [Male] 32653 from 6 mi. W San Antonio de las Alazanas, July 5, 1955; and [Male] 31602 from 14 mi. W San Antonio de las Alazanas, 6500 ft., January 7, 1954.
Although there are no records in Coahuila of specimens of Burrowing Owls north of 3 mi. S and 9 mi. E Cuatro Ciénegas, this owl probably occurs in the northern section of the State. The records of Burrowing Owls from the southern part of Brewster County, Texas (Van Tyne and Sutton, 1937:38), suggest such occurrence. No. 31602 was shot in a prairie dog colony; No. 32043 was captured in a steel trap. Baker saw Burrowing Owls 7 mi. S and 4 mi. E Bella Unión, 7200 feet, on June 25, 1952.
