woodpecker drum of two notes only, delivered rapidly with force 

 and emphasis, with a pause before repetition, that brought to mind 

 immediately the similar performance of the related Phloeoceastes 

 It vcopogon of northern Argentina. And following this sound and 

 the loud hammering that accompanied it, I collected a fine pair of 

 P. g. regius. Others were observed and heard regularly throughout 

 my stay. Carriker secured three near Hueyapa on March 8 and 25, 

 1940, including two fully grown young birds in juvenal plumage. 

 These are strong-muscled, robust birds with tough, thick skins, so 

 that their preparation as specimens entails definite physical labor. 

 A needle will scarcely penetrate the thickened skin of the back of 

 the head. 



Following are measurements of the adult specimens: 2 males, 

 wing 190, 195.5, tail 103.3, 105.4, culmen from base 56.2, 51.0, tarsus 

 38.2, 38.2 mm.; 1 female, wing 185.5, tail 111.3, culmen from base 

 47.5, tarsus 33.7 mm. 



The race regius is separated from typical guatemalensis solely 

 by average larger size, there being definite overlap in dimension. 

 The birds from the Tres Zapotes area come within the limits set 

 for regius and are so identified, though it must be stated that the 

 form is based on differences that are not at all sharp cut or trench- 

 ant. 



CEOPHLOEUS LINEATUS SIMILIS (Lesson) 



Picas simUis Lesson, Oeuvres completes cle Buffon, vol. 20, Apr. 1S47, p. 204 (San 

 Carlos, El Salvador). 



The five specimens secured were obtained near Tres Zapotes March 

 15 and 16, 1939, and January 26 and March 3, 1940, and Hueyapa, 

 March 15, 1940. 



The species was fairly common through wooded areas, coming 

 into the more open second growth, and into dead trees in the fields 

 where clearings bordered the forest. It was known locally only by 

 the name carpintero applied to all woodpeckers. I heard them 

 uttering a chattering call that was not unlike that of a Cen funis, 

 while the drum was a loudly resounding, rapid roll, slowing slight- 

 ly toward the end. It resembled the sound made by Ceophloeus 

 pileatus of the North but was slightly slower. The flight is bound- 

 ing, and seemed somewhat heavier than that of the pileated wood- 

 pecker. On April 8 I found a pair working on a nest hole 50 feet 

 from the ground in a dead tree at the border of a tract of forest. Two 

 days later I noted one looking out from a nest hole cut 20 feet from the 

 ground in a dead tree trunk standing in an old field.
