208 PROCEEDINGS OF THE ACADEMY OF [1890. 



55. Myiarchus yucatanensis Lawr. Yucatan Crested Flycatcher. 



Quite common about the haciendas. Two specimens were shot 

 near Tekanto. 



56. Contopus albicoUis Lawr. "W^hite-throated AVood Pewee. 



Specimens were shot near Tekanto and also near Shkolak. 



57. Empidonax minimus Baird. Lea.st Flycatcher. 



Seen at Ticul, Tunkas and Tekanto. Rather common. 



58. Pyrocephalus rubineus mexicanus (Scl.). Vermiliun Flycatcher. 



This bird was common on the mud flats bordering the mangrove 

 swamps at Progreso and seems to be restricted to the coast region as 

 none were seen inland. The specimens collected are of a more rosy 

 red than those from Orizaba, Mexico. 



59. Cissolopha yuca ta (DuBois). Yucatan Blue Jay, 



The Jay is common throughout the interior but seems to be more 

 abundant in the dense forest surrounding the aguadas at Shkolak, 

 where large flocks were frequently seen. 



60. Xanthoura luxuosa cyanocapilla (Cab.). Yellow-bellied Green Jay. 

 Seen at Tekanto, Izamal and Ticul, always close to the towns. 



61. Callothrus robustus (Cab.). Red-eyed Cowbird. 



Abundant in the cow yards of the haciendas, continually flying 

 about the cattle, in company with Dives. 



62. Agelaius phoeniceus (Wagl.). Red-winged Blackbird. 



Several pairs seen on the edge of the Mangrove swamps at 

 Progreso, March 20. 



63. Icterus auratus Bp. 



One male shot and several others seen near Tekanto, always in 

 company with the following. 



64. Icterus gularis AVagl. 



This bird was abundant throughout the interior and, with the 

 exception of the one above mentioned, all the orioles shot belonged 

 to this species. It is strange that this species which we found so 

 common is not mentioned in Mr. Boucard's list of the birds collected 

 in Yucatan by Dr. Gaumer, and that the sj^ecies described by him 

 as abundant were not seen at all by us. 



Perhaps the breeding districts of the various species are different 

 and one species may predominate in Northern Yucatan at one time 

 and be succeeded by another. We saw no females of this species
