1867.] MR. O. SALVIN ON THE BIRDS OF VERAGUA. 1 13 



This species has not heeu noticed before as occurring so far south, 

 though specimens of the second Central American bird of this genus 

 (S. guatemalensis) have been sent from Panama. The two examples 

 contained in these collections are neither of them in good condition ; 

 they appear to differ slightly from our Guatemalan specimens, the 

 uropygium being somewhat darker and the bill shorter. 



4-77. Synallaxis albescens, Temm. PI. Col. 227. f. 2; Scl. 

 Cat. Am. B. p. 151. 



Santa Fe. 



A single example of a. Si/naUaxis agrees closely with Sclater's spe- 

 cimen from Trinidad, which he ascribes to »§. albescens, Temm. 

 Four species of Synallaxis have been recorded as occurring in Central 

 America, viz. S. erythrothorax, Scl., of South Mexico and Guate- 

 mala ; S. jniclica, Scl., Panama ; (S. albescens, Temm., Veragua ; and 

 S. nigrifumosa, Lawr. Ann. N. Y. Lye. viii. p. 180, Greytown, Ni- 

 caragua. I have not seen specimens of this last mentioned. It 

 seems to be very closely allied to .S*. j9»^7/c«, perhaps the male of that 

 species ; a specimen with the sex so marked from Panama differs 

 from the female in the greater intensity of the smoky-black tinge of 

 the under plumage and in the brighter shade of chestnut, distinc- 

 tions upon which Mr. Lawrence rests the claim of the species he 

 describes to specific rank. 



-f- 7S. Xenops mexicanus, ScL 



Santa Fe. 



Also noticed on the Panama Railway. 



-+- 79. AUTOMOLUS CERVINIGULARIS, Scl. 



Santa Fe. 



Mr. M^Leannan, according to Mr. Lawrence, also procured this 

 species on the Isthmus of Panama, where, however, another of this 

 form {A. 2)allidigularis, Lawn*.) occurs. 



-r 80. Philydor fuscipennis, Salvin, P. Z. S. 180(5, p. 72. 



Santiago de Veragua. 



This is the second species of this genus now known to occur in 

 Central America, the other being P. rvfobrunyieus, Lawr. (Ann. 

 L. N. Y. viii. p. 127), from Costa Rica. 



-f- 81. Margarornis brunnescens, Scl. 



Cordillera de Tok'. 



A single specimen sent by Arcc only differs from Sclater's type of 

 M. brunnescens in having the rump slightly darker rufous, the dif- 

 ference not being sufficient to warrant specific separation. It is pro- 

 bably this bird that jNIr. Lawrence refers to (Ann. N. Y. Lye. viii. 

 p. 130), where he suggests the possibility of a Costa Rica specimen 

 being different from bmnneseens, and proposes the name brunnei- 

 cmida should his surmise prove correct.
