(2553) Xiphorhynchus insignis {Hellm.). 



Dendromis insignis Hellm., Bull. B. O. C, XV, 1905, p. 56 (Samiria, n. e. 

 Peru). 



On comparison with X. elegans and X. occellata a specimen from Floren- 

 cia shows the distinguishing featm'es on which this species is based, but 

 two males and a female from Buena Vista are decidedly paler throughout.

Thxee specimelis from Villa vicencio agree with two others from Maipures 

 and San Fernando de Atabapo, in having the throat slightly whiter than 

 specimens from Cayenne, British Guiana, Santarem, and Bahia. Possibly 

 the difference may be due to the freshness of the skins, which, in other re- 

 spects, are typical. 



This form appears not to have been previously reported from the Bogota 

 region, in which, as recorded below, D. p. picirostris also occurs.

Inhabits the arid coastal Zone and southward up the Atrato and Mag- 

 dalena Valleys. Our seven specimens agree with a large topotypical series 

 from Bonda, near Santa Marta. In this form the bill averages stouter 

 than in picus but, aside from the fewer black margins on the feathers of 

 the throat, I observe no constant difference in color between the two forms.
