NOTES' ON GUATEMALAN BIRDS' — WETMOiRE 575 



out of a cornfield to alight in a tree where I killed two, one adult 

 and one immature. Many seen through the cornfields of this section 

 were in various stages of molt, some being without tails. Near Lake 

 Atitlan thej' were common but were not so widely distributed as 

 in the valley at Antigua and Duenas. In evening I noted them in 

 flocks of 50 or 60 along the lake shore, and saw them in flight to- 

 ward some roost. On December 3 I observed many from the train 

 between Guatemala City and Puerto Barrios, particularly along the 

 Rio Motagua. 



The country people called the females sanates and the males claar- 

 ineros. 



TANGAVIUS AENEUS AENEUS (Wagler) : Red-eyed Cowbird 



PsarocoUus aenens "Lichtenst." Wagler, Isis von Oken, vol. 22, pt. 7, July 

 1829, col. 758 (City of Mexico). 



On November 2, near Duenas, I found a flock of 40 or 50 feeding 

 packed closely together on the ground beside the road. They were 

 busily intent on their own affairs and paid little attention as I 

 stopped the car; and got out with the gun. I selected two at one 

 side, but as I pulled the trigger the flock was disturbed and I secured 

 10, a welcome series when I came to examine the birds, as they 

 showed various stages in molt. 



Van Rossem^* from a study of Wagler's type has found that 

 aeneus is the bird currently known as involucratus and that the type 

 locality is the City of Mexico. 



GYMNOSTINOPS MONTEZUMA (Lesson) 



Cacicus Montezuma Lesson, Centurie zoologique, livr. 2, Oct. 1830, p. 33, pi. 7 

 (Mexico). 



At Puerto Barrios on December 4 half a dozen flew overhead 

 with straight, direct flight. 



C. W. Richmond in the card catalog in the division of birds, U. S. 

 National Museum, has noted another citation for the original descrip- 

 tion, viz., Cassicm Montezti/ma Lesson, in Ferussac's Bulletin des 

 Sciences Naturelles et de Geologic, vol. 19, December 1829, p. 324, 

 where reference is made to plate "8" ( = plate 7) of the Centurie 

 Zoologique published in 1830, with the notation "Espece nouvelle et 

 tres-belle de Cacique du Mexique, a bee rouge et noir, a plumage 

 Marron." This reference I have not seen noted elsewhere.
