Tache latirostris of the Check-List thus becomes 
441. Cynanthus latirostris SwWAINSON. 
No. 441.1 becomes a subspecies of Platypsaris aglave. (Cy. 
Ripeway, Bull. U.S. Nat. Mus., No. 50, Pt. IV, 1907, 856), viz.: 
441.1. Platypsaris aglaie albiventris (LAWRENCE). 
449. Pitangus derbianus (Kaur). This is reduced to a sub- 
species, as 
449. Pitangus sulphuratus derbianus (Kaur). (Cf. Ripaway, 
Bull. U.S. Nat. Mus., No. 50, Pt. IV, 1907, 672.) 
453. Myiarchus mexicanus (Kaur). ‘This is changed to 
453a. Myiarchus magister nelsoni Ripaway. 
Myiarchus magister nelsoni Ripaway, Bull. U.S. Nat. Mus., 
No. 50, Pt. IV, 1907, 903. 
Myiarchus mexicanus of Kaup proves to be equivalent to M. 
cinerascens, Which name, having priority, is retained. (C7. OsGoon, 
Auk, XXIV, 1907, 219, 220.) 
No. 453a of the Check-List becomes 
453. Myiarchus magister (Ripaway). 
GENUS SAYORNIS Bonarartre. Authority changed to 
GENUS SAYORNIS G. R. Gray. 
Sayornis Gray, Cat. Genera Birds, 1855, 146. Type, Muser- 
capa saya BONAPARTE. (Cf. Stone, Auk, XXIV, 1907, 196.) 
GrENUs CONTOPUS Caxnanis. ‘This is preoccupied, and becomes 
GENUS MYIOCHANES Capanis & HEINE. 
Myiochanes Capants & Heine, Mus. Hein., II, 1859, 71. 
Type, Platyrhynchus cinereus Sprx. (Cf. Ripaway, Bull. 
U.S. Nat. Mus., No. 50, Pt. IV, 1907, 509.) 
Mytochanes cinereus (Sr1x) is held to be congeneric with the 
Wood Pewee and its allies, and Myiochanes is therefore available 
for this group in place of Contopus.
