°1918 J Proposed Changes in the A. O. U. Check-List. 203 



Sula Candida Stephens = Pelecanus sula Linnseus). Recognized as 

 a genus. (Cf. Mathews, Birds Australia, IV, pt. 3, June 23, 1915, 

 p. 199). Includes one species now in the genus Sula: 

 Piscatrix sula (Linnaeus). 

 Sula piscator (Linnseus) becomes Piscatrix sula (Linnaeus), since the 

 latter proves to be identical with the bird currently known as Sula 

 piscator. (Cf. Mathews, Buds Australia, IV, pt. 3, June 23, 1915, 

 pp. 206-209.) 



fParasula Mathews. New genus. Mathews, Austral Avian Record, II, 

 Nos. 2-3, Oct. 23, 1913, p. 55 (type, Sula daclylatra bedouti Mathews). 

 Includes the following North American species now in the genus Sula: 

 Parasula cyanops cyanops (Sundevall). 

 Parasula nebouxii (Milne-Edwards). 



jMorus Vieillot, Analyse Nouv. Ornith. Element., 1816, p. 63 (type, 

 Pelecanus bassanus Linnaeus). Recognized as a genus. (Cf. Mathews, 

 List Birds Australia, 1913, p. 98; Birds Australia, IV, pt. 3, June 23, 

 1915, p. 217). The only North American species is now in the genus 

 Sula and will therefore stand as: 

 Morus bassanus (Linnaeus). 



Phalacrocorax carbo (Linnaeus) becomes Phalacrocorax carbo 

 americanus (Reichenbach) (Graculus americanus Reichenbach, 

 Novit. Synop. Avium, Natatores, Dec, 1850, p. [3], pi. CCCL [ = Novit. 

 LXXXVII = XXXV 8 ]; North America), by recognition of the 

 North American bird as a distinct subspecies. (Cf. Mathews, Birds 

 Australia, IV, pt. 2, Feb. 17, 1915, p. 171.) 



Fregata aquila (Linnaeus) becomes Fregata magnificens rothschildi 

 Mathews (Fregata minor rothschildi Mathews, Buds Australia, IV, 

 pt. 3, June 23, 1915, p. 280; Aruba Island, Caribbean Sea), since 

 Fregata aquila (Linnaeus) proves to be extralimital. (Cf. Oberholser, 

 The Auk, XXXIV, No. 4, Oct., 1917, pp. 468-469.) 



t Fregata minor palmerstoni (Gmelin). Pelecanus palmerstoni Gmelin, 

 Syst. Nat., I, ii, 1789, p. 573 (Palmerston Island, Pacific Ocean). 

 Revived by Mathews (Austral Avian Record, III, No. 6, Dec. 19, 

 1914, p. 119; Birds Australia, IV, pt. 3, June 23, 1915, p. 280), for the 

 bird of the central Pacific Ocean. Occurs also northeast to California. 

 (Cf. Oberholser, The Auk, XXXIV, No. 4, Oct. 1917, p. 469). 



fAnas rubripes tristis Brewster, The Auk, XXVI, No. 2, April, 1909, 

 p. 176 (new name for Anas obscura Gmelin). Reinstated as a sub- 

 species. (Cf. Oberholser, The Auk, XXXIV, No. 2, April, 1917, 

 pp. 192-194.) Range: northeastern United States to central Quebec 

 and coast of Labrador; in winter south to the Gulf of Mexico. 



fErismaturinae. Revived as a subfamily. (Cf. Mathews, Birds Aus- 

 tralia, IV, pt. 1, Oct. 6, 1914, p. 8.) Includes the North American 

 genera Erismatura Bonaparte and N oniony x Ridgway. 



fDendrocygninae. New subfamily. Shufeldt, Zool. Jahrb. (Abth. f. 

 Systematik), XXXVIII, 1914, pp. 1-70, pis. I-XVI. Includes the 

 genus Dendrocygna Swainson.
