55. Petrochelidon swainsoni, Sclater, P. Z. S. 1858, p. 296, 



Oaxaca : 3 et $ similes. Two pairs of this very beautiful Swal- 

 low quite confirm the validity of this species as distinct from P. 



Junifrons and P. fulva.

56. Ptilogonys cinereus (Sw.). 



Totontepec (Jan.). The eggs of this bird, sent by M. Boucard 

 from Oaxaca (May 1858), are minutely freckled and striated with 

 brownish ash-colour on a white ground, the markings being denser 

 and forming a ring round the large end. They measure *875 by 

 •61 inch. They somewhat resemble some varieties of those of An- 

 thus pratensis. 



57. Myiadestes obscurus (Lafr.). 

 Totontepec (Jan.). 



M. Boucard has forwarded five eggs belonging to this bird, taken 

 at Yoletepec in May 1858. They are very Robin-like in appearance, 

 being white, minutely spotted and freckled with reddish brown, par- 

 ticularly at the larger end, where the spots cover nearly the entire 

 surface. They measure 0 - 95 by 0*75 inch.

 Ccereba cyanea, Sclater, P. Z. S. 1856, p. 286. 



Assimilis C. cyaneae, ex Cayenna, et rostro breviore, tenuiore, 

 pilei colore turcoso magis restricto, nucha cum lateribus capitis 

 concolore, et pedibus vivide carneis specifice vix distinguenda. 



Hab. In rep. Mexicana. 



There seem to be minute differences which always distinguish this 

 bird from its S. American representative, though it is questionable 

 whether they are sufficient for specific separation. The present 

 examples were obtained at Playa Vicente. M. Salle procured others 

 at Cordova. I have not yet seen examples of this bird from Guate- 

 mala.
