158 DENDEOCOLAPTIDJE. 



This is the palest of all these forms on the upper surface, and, moreover, has the 

 forehead and anterior portion of the crown of the same colour as the back, instead of 

 being of a uniform dark cinnamon or rufous-brown tint over the whole crown ; the 

 sides of the head below the eyes are also clearer cinnamon than in any of the allied 

 forms. In other respects it most resembles the Guatemala bird from the Volcanoes of 

 Agua and Fuego. 



Mrs. Herbert -Smith's large collection made in the Sierra Madre del Sur in the 

 summer of 1888 contains two specimens of this species — the male taken at Omilteme 

 at an elevation of 8000 feet above the sea; the other, marked female, at Xautipa, a 

 village in the same range of mountains, both places being not far from Chilpancingo, a 

 town on the road from the port of Acapulco to the interior. 



The female differs slightly from the male in the almost total absence of the rufescent 

 colour on the nape, the upper surface being thus almost uniform as far as the rump. 

 We have not enough specimens to be able to judge if this difference is a normal one 

 between the sexes, but from analogy it would not be so.

On the upper surface this is the darkest of all these forms of Automolus, darker even 

 than A. ruUginosus, and has much darker wings. On the underside it is more like 

 the Guatemalan A. umhrinus, but the sides of the head and flanks are much darker 

 and the wings outwardly very differently coloured. 



Of this species we have only a single male specimen, which was sent us by our 

 collector, Enrique Arce, in one of his last collections. He obtained it near a place 

 called Bibalaz, on the slopes of the Volcan de Chiriqui.
