II. CHANGES OF NOMENCLATURE. 



Genus Engyptila Sundevall (p. 180). This becomes 



Genus Leptotila Swains. 



LeptotUa Swains. Class. Bds. II, 1837, 349. Type, '•'•P. nifaxilla. 

 Nat. Lib. V. pi. 24" [/. ^., Peristera jamaicensis, Nat. Lib. 

 IX, 207, pi. 24 (named on plate '■'■ Peristera riifaxina'") ]. 



Leptotila Swains, has thirty-five years' priority over Engyptila 

 Sundevall. The former name has been generally discarded as 

 being preoccupied by Leptoptilos Vieillot, 183 1. on the presump- 

 tion that Swainson intended to write Leptoptila : but there being 

 no satisfactory evidence that this was the case. Leptotila is 

 accepted as a tenable name. 



No. 318. Engyptila albifrons [Bonap.). This becomes 



Leptotila fulviventris brachytera (Salvad.). 

 Leptoptila brachyptera Salvad., Cat. Bds. Brit. Mus. XXI, 1893, 



545- 

 Leptotila fulviventris brachyptera A. O. U. Comm. Nomen. MS. 



Professor Salvador! (1. c, p. 545, footnote) has found that the 

 type of Z. albifrons Bonap. in the Paris Museum "is undoubtedly 

 a specimen of L. jainaicensisy The earliest specific name for 

 No. 318 of the Check-List appears therefore to be brachyptera 

 Salvad. 1893 {ex Gray, 1856, nomen nudiwi). while brachyptera 

 appears referable as a subspecies to L. fulviventris Lawr. (Ann. 

 New York Acad. Sci. II, 1882, 287). 



No. 421. Chordeiles texensis Lawr. This becomes 



Chordeiles acutipennis texensis (Lawr.). 



Chordeiles acutipennis, var. texensis Baird, Brew. & Ridgw. 

 Hist. N. Am. Bds. II, 1874, 406. {Cf Hartert, Cat. 

 Bds. Brit. Mus. XVI, 1892, 616.) 



Genus Picicorvus Bonap. This becomes a subgenus of 

 Nucifraga. Cf. Ridgw. Auk, XI, April, 1894, 179.
