I follow Ridgway (Bull. U. S. N. M., 50, VI, p. 711) and Berlepsch (Bull. 

 B. O.C., XII, p. 8) in referring Colombia specimens to this form. A Da- 

 beiba female is rufous above and in part below, and a female from Villa- 

 vicencio is intense rufous both below and above. It doubtless represents 

 the extreme development of this color phase of which Berlepsch (l. c.) also 

 records Bogota specimens.

(697) Otus watsoni (Cass.). 



Ephialtes watsoni Cass., Proc. Acad. N. S. Phila., IV, 1848 (So. Am.); Journ- 

 Acad. N. S., Phila., II, 1852, p. 95, pi. xii, fig. 1. 



Scops usta Scl., Trans. Z. S., IV, 1862, p. 265, pi. 61 (Ega, Upper Amazon). 



Of two Owls collected by Miller at La Morelia, one agrees with the 

 plate of Sclater's " Scops usta" (I. c.) the other is less tawny in color and ap- 

 proaches Otiis watsoni (Cass.), the types of which have been loaned me by 

 Dr. Witmer Stone. 



This -specimen, therefore, indicates that this species has a gray and a 

 rufous color phase and tends to confirm the belief that usta, founded on the 

 latter phase, is a pure synonym of watsoni founded on the former. (C/. 

 Berlepsch, Bull. B. O. C, XII, 1901, p. 10; Hellmayr, Nov. Zool., XIV, 

 1907, p. 407).

(699a) Lophostrix cristatus Strickland! Scl. & Salv. 

 Lophostrix stricklandi Scl. & Salv., Ibis, 1859, p. 221 (Vera Paz, Guatemala). 



Two of three specimens from Barbacoas agree essentially with others 

 from eastern Panama and Nicaragua; the third has the face more rufous 

 and probably therefore approaches true cristatus.
