390 Fourteenth Supplement to the A. O. U. Check-List. {j^ 



Oceanodroma heldingi Emerson, Condor, VIII, 1906, 54. This 

 and the preceding appear to be indistinguishable from 0. leucorhoa. 



Oceanodroma monorhis chapmani Berlepsch, Auk, XXIII, 

 1906, 185. This proves to be a phase of plumage of 0. socorroensis. 



DilophaUeus (cf. Coues, Key, 5th ed., 1903, 962). Not ad- 

 mitted, the proposed subgenus being based on insufficient characters, 



Viguacarbo (cf. Coues, Key, 5th ed., 1903, 963). The characters 

 of this proposed subgenus are not deemed sufficient for recognition 

 in the List. 



127. Pelecanus califomicus vs. P. fuscus [= occidentalis] cali- 

 jornicus (cf. Ridgway, Proc. U. S. Nat. Mus., XIX, 1897, 

 593; Hartert, Nov. Zool., VI, 1899, 176; Twelfth Supple- 

 ment, Auk, 1903, 363). 



A change in status is considered unnecessary. 



Merganser vs. Serrator (cf. Stone, Auk, 1907, 194). No change 

 required. (See under 'Changes in Nomenclature,' antea, p. 360.) 



160. Somateria dresseri vs. S. mollissima dresseri (cf. Hartert, 

 Bull. Brit. Orn. Club, XV, 1904, 44). The change is deemed 

 unnecessary at present. 



Melanitta vs. Phaonetta (cf. Stone, Auk, 1907, 198). Proposed 

 change based on the "first species" rule. 



Exanthemops vs. full genus (cf. Twelfth Supplement, Auk, 1903, 

 368). Elevation to generic rank not considered desirable. 



171.2. Anser brachyrhynchus vs. Melanonyx hrachyrhynchus, and 



[171.1.] Anser fabalis vs. Melanonyx segetum (cf. Buturlin, 

 Wild Geese Russian Empire, 1901, 22; Salvadori, Ibis, 

 1905, 530). Melanonyx is not thought worthy of recognition, 

 being based on slight characters, and fabalis, as the specific 

 name of the Bean Goose, has priority over segefmn. 



Plegadis vs. Egafheus (cf. Lonnberg, Journ. f. Orn., 1906, 533),
