an inch or an inch and a half of the bottom, and without any lining of 

 soft material. One of the nests is much more bulky than the other, 

 having a transverse diameter of 7 inches, instead of only 5, as in the 

 other. 



" The [three] eggs are grayish white, thickly streaked, blotched and 

 spotted with dark lavender, and with a few overlying streaks and spots 

 of dark chocolate. In one egg tbe streaks and spots are more sharply 

 defined and darker than in the other two. Size, 19X44-" 



277. Pachyrhamphus cinnamomeus magdalenae Chapman. 

 Fifteen specimens: Fundacion and Tucurinca. 



The peculiarities of these specimens, which are superficially much 

 like females of P. rufus, were noted soon after their receipt, and their 

 resemblance to P. cinnamomeus remarked. Shortly thereafter Dr. 

 Chapman (Bulletin American Museum of Natural History, XXXIII, 

 1914, 629) described a bird from Algodonal, Magdalena River, under 

 the name Pachyrhamphus magdalcncc, which was obviously the same 

 thing, and this identity has since been confirmed by actual comparison. 

 The species belongs to the P. cinnamomeus group, in which the sexes 

 are alike; it is much paler than that form, however, especially below, 

 the abdomen being nearly white in some specimens. Males are of 

 course very different from the same sex of P. rufus, but females are 

 very similar at first glance. They may invariably be distinguished by 

 the pattern of the brown margin of the outer webs of the remiges, 

 which is not sharply defined from the dusky inner portion, as in P. 

 rufus. They are also a little larger than the same sex of that species.
